If you've been waiting for the new Samsung Galaxy S22 device, then the team at Appalachian Wireless has some good news for you. Appalachian Wireless is launching all Samsung S22 models on sale. We are you. We are Appalachian Wireless. The city of Pikeville and Brake Center State Park will begin conducting a feasibility study to discuss recreational opportunity next week. In response, Mountain Top spoke with city manager Philip Ellswick about the opportunity. The city was awarded a $50,000 ARC power grant to look at revitalization of the economy and we partnered with Brakes Center State Park to look at ways that we can partner together to improve tourism for both entities. The Brakes has awesome outdoor recreation, but they don't have a lot as far as restaurants, nightlife, shopping, things of that nature, and nothing really even close right there in the area. So, we believe that there's some synergism between the two entities that maybe we can provide those things and they can provide outdoor recreation, which is a big part of our comprehensive plan that the commission adopted last year. In hopes of engaging in entrepreneurial opportunities, both Brakes Center State Park and the city of Pikeville will be conducting public input sessions to discuss options for collaboration. We're looking at Pikeville being kind of the hub, that we would provide the restaurants and the hotels and the shopping and things of that nature. And then the Brakes would be a destination for outdoor recreation, just to be in nature. There's a lot of components that build on one another. Part of our comprehensive plan was a health and wellness tourism. So people may come here and this is part of that experience, but a lot of it's also in the Brakes, where they go for rejuvenation and to be in nature. There's also just the part that people that are here for a day or so, maybe they're here on a Saturday waiting for a concert that night. They might be interested in going to the Brakes to hike or fish and we would provide that transportation for them and then we would bring them back that evening. So there's a lot of different components that we're debating and talking about, but next week there are a couple of public input sessions that if the general public has ideas of what that relationship may look like and the things that we need to build on that relationship we would very, very much value your input. The public input session will be held March 8th from 2pm to 4pm and 5.30pm to 7.30pm at the Main Street entrance of the Appalachian Wireless Arena 126 Main Street in Pikeville.

What's going on guys, welcome to my nought to 10K beginner strategy. This video is for the person, the beginner who wants to start a dropshipping business. They understand how the business model works. They know the kind of components that are involved in starting a dropshipping business, but they're feeling a bit overwhelmed, a bit of analysis paralysis, they've watched countless YouTube videos and they're not quite sure how to put all of the different pieces together. So today I'm going to take you through the different actions you should take in order step by step. Before we get into the different components then, it's worth noting what those components are. So there's four components that go into any successful dropshipping business and then within each of these components of course there's a lot more components which we'll be covering in the video. So the main four components you can see on the screen here is your product. Every business of course needs a product to sell. Every business needs a store to sell that product on, some kind of platform whether it's a landing page on ClickFunnels or whether it's an e-commerce website on Shopify. They of course need a supplier for that product, whether it's a Chinese supplier, it's a local supplier in the country you're currently sat in or whether you're making the products yourself, you need a means to source it or making the product and then of course marketing. You need a way to put your product in front of your target audience. Without these four components your business will fail and all four of these components are key as well. You can't have one without the other. So for example if you have a brilliant product, a brilliant store and a brilliant supplier but then you have no means to marketing the product and getting it in front of people the business is ultimately going to fail. You could pay 10 grand for a website, you could have a supplier that can deliver same day and you could have an unlimited marketing budget but if you have a crap product that nobody is interested in and nobody wants to buy the business is going to fail. So basically either way you do it you need all four of these components and you need to do them really really well. So let's jump into arguably the most important component to any business. Well I think it is because it's where every business starts without a product you have nothing to sell and you have no way of making money. So this strategy has been built to get you results as quickly as possible. As a beginner getting into something new especially something like a business which has time and financial commitments and risks especially the job shipping business too where there's a lot of conflicting information on YouTube it can be difficult to know whether this is all just kind of smoke and mirrors or whether it actually works or not. So in the beginning at least from what I found with the people that I work with it's super super important to get them that win and get them that results and get them that first few sales as quickly as possible because then they become more motivated any kind of hesitations they had about the business model instantly diminish and they become a lot more invested or willing to invest into their business. So of course I'll take you through the kind of key things the most important things of each of these components you need to consider perhaps I could do a more detailed video on each of these components and kind of like a mini course or mini series but ultimately I do this YouTube channel for you guys so make sure you let me know what it is you want to see and I can produce some content on the idea. So when it comes to products then go for a trending product to see results fast. Don't try and find a product that nobody else has sold don't try and reinvent the wheel don't try and design a product from scratch is going to cost a lot of money go for something that you know for a fact is already selling and make sure it's a drop shipping product to make sure it's a product that you can source from AliExpress or is available on AliExpress because a drop shipping product that works versus just a typical e-commerce products that works two completely different things so for example to illustrate that is that when a lot of people will begin as especially the mistake they'll make is they'll go on to AliExpress and they'll see a product that has 10,000 orders and they think oh that's a winning product that's not the case AliExpress is not a drop shipping supplier yes they supply products and they can supply it directly to your customer so you can use them as a drop shipping supplier but the main bulk of their revenue and sales and those order numbers you see do not come from dropship as they are end users they are consumers so just because somebody is willing to buy it directly from AliExpress does not mean that they're willing to pay an extra 10, 15, 20 pounds on top of the AliExpress price to buy it from you and that kind of skips us or jumps ahead to point number three make sure there's a minimum of $20 margin so whatever you buy your products for including everything including shipping costs including any customers fees import fees whatever the cost is of that product delivered to your customer's doorstep you need to be able to sell the product for a minimum of $20 more if you can do that and find a product that does that for you then you have the potential to run a business that makes you a profit pretty much from day one obviously there's loads and loads of other things to consider but $20 room if not more is a good benchmark to be looking for so go for a training product to see results fast that way you know the product is in demand that way you know the product is already working and once you've found a product using platforms like exploding topics strappers by tour store hunter minor or many a then you can find everything else behind that business too so when you see somebody advertising a job shipping product and it's working you can see the ad creative they use and you can see the landing page that they're using you can't always see what supply they're using but out of the four components the suppliers probably the easiest one to be fair and we'll cover more of that in a second so using these tools you'll be able to find those posts on tiktok those posts on Facebook on Instagram on Pinterest on all of these different social media platforms and you can vet them you can see the engagements behind them you can see the comments you can see the order history you can see all that good stuff so you know that you have a winning product on your hand and then you see what that business is currently doing to make it winning products that you can then use as inspiration the only in full transparency of course the only downside to using this as your strategy when it comes to finding a product is number one is competition when something appears on one of these platforms there's going to be a lot of other people trying to sell it so just make sure that you do things better than the person that you can currently see is selling it yes I can't think of an industry in this world that isn't very competitive and people don't just not come into competitive markets because it's impossible to win that's not the case you just have to do things better have a better store have a better creative that sort of thing so just make sure that you take care of the rest of these three other components and you'll be good to go the second disadvantage that you do need to be aware of because I made this mistake when I first started is that trending products are trending products because they go through a cycle of being out of trend they go up in trend and up in power popularity they hit a peak and then they come back down and out of you want to find a product that is at the very beginning or if not slowly starting to go up so you can kind of ride the roller coaster up when you get kind of halfway down that is when you need to then be looking for the next product to replace the current income and a product that currently has demand for the for the seasonal time of year that you're coming into so for example if we take I always use the pet niche because it's my favorite niche of all the two kind of polar opposite seasons I suppose in the UK here even though summers can be like winter sometimes obviously have winter it's dry obviously have summer sorry it's dry and it's warm so you have products like paddling pools for dogs or cool mats for dogs or walking bottles that allow you to keep your dog cool during the summer or you have like water games in the garden that sort of thing so as you're coming into summer in the UK you would start selling nose you would ride the wave ride the wave and then when the clocks go back and the weather starts to change sort of like September ish time you would then turn your attention to winter type products like reflective rain jackets or she lays to keep dogs warm or protectors for the car or protectors for the sofa to keep mud off it so that's the only thing you need to be aware of is just make sure that when you do pick one of these trending products that you start selling it at the right time and just make sure that you're always looking kind of two or three months ahead for when that product comes out of season so you have something else to replace it with so that's your starting point that is the first step that you need to find yourself a product that you're going to be selling this is purely just to like I mentioned earlier in the video to boost your motivation verifying your own mind that the business model does work and develop your skills we're not really interested in having a long term business or brand at this point you just need to get familiar with everything and the pitfalls and hurdles and the stresses and difficult things that you'll have to overcome and skills you have to develop if you are planning on doing this for the long run and by having products that come in and out of trend you'll learn pretty much everything you need to learn when it comes to product selection when it comes to design in stores and when it comes to marketing as well so once you've kind of been through a couple of cycles it will put you in a nice position where you have the skills and confidence to build something in the long run and if you've done things well up to this point as well you should have some cash in the bank which then allows you to invest in that long term brand and do things to a high level right from the very beginning from let's move on to component number two then so store there's a store is like it's so underestimated from a lot of people so 90% of the people that I work with on a one to one basis they already have a store they've already tried drop shipping and more often than not the store is just not up to scratch and it needs significant amounts of work to get it up to scratch and it's usually the simple things where I see them falling down so number one try and stay away from general stores general stores for a fact do not convert as well as a branded niche store and when I say branded niche store I mean a store that sells products just for dogs versus a store that sells products for dogs cats fish sports people camping stuff home where that sort of thing people want to buy from an expert in their subject in their field because they assume that they get a better higher quality product so here's a great example if you're watching this from the UK if you want to take your family out for if you want to get your family a really nice Indian meal are you going to go to an Indian restaurant that only serves Indian food or are you going to go to one of these takeaways that serves Indian food Italian food English food and Chinese food all in one you're probably going to go to the Indian restaurant because that's what they specialize in same thing applies to e-commerce people like to go to a brand because it gives off the impression that they care more and they're they're experts in their field and therefore they're much more likely to supply a quality product so that's why you should stay away from general stores unless of course you are going and trying to capture the entire market and those kind of like bargain basement type stores but when you're working on type margins and drop shipping is type margins then I don't think that's a good route to go next we have social proof social proof is everything if you follow the channel I pretty much mention this in every video because it's so so important think about it you're scrolling through your newsfeed your spine looking up and what your friends are doing and then this ad pops up for this product the interruption day but it looks pretty cool and you want to find out more information about it you go into their facebook page they've got zero likes zero followers the last post was so-and-so company updated their profile picture the page was created two months ago you go into their website there's no reviews or if there are reviews of they look fake because they're broken English they're gibberish they don't really make sense you're not going to trust that business you're certainly not going to risk giving across your credit or debit card details so social proof is everything every single page on your website should have reviews reviews of your business reviews of the products and they should make sense and they should look realistic as well if you do not if your customers do not trust you they will not buy from you and that is a fact next we have put the logo everywhere including on the product so check out a company called nano cast they sell this portable it's like a barrel shaped projector that you can charge up and take with you wherever you want you can shine Netflix on your ceiling you can shine on your wall you can shine on your bedsheets and on their website they have the logo clearly on the actual product itself in your product imagery scroll down into the reviews there's no logo on any products but by having that logo shown on the product it makes them look so much more professional and so much more established and remember when we're dropshipping we're using dropshipping as a business model for a proof of concept a way to reduce risk before we invest into private labeling a product so amazon fba you can't dropship on there for a couple of hundred quid to see if your product works before investing in hundreds if not thousands of pieces of stock which costs you thousands of pounds whereas with dropshipping we can we can dropship a product for a few weeks see if it works and spend just a few hundred pounds maybe a grand or so and if it does work then look to private label and invest into the product before so it's a way of kind of testing it works to reduce the risk before we go ahead and do that in terms of the design keep it simple don't try and reinvent the wheel don't go for a black background in red text unless it's a halloween store or something like that just keep design simple check out some competitors people selling the same products check out some stores on dropper spy or on store hunter and check out the kind of strategy they're using what color their backgrounds are what fonts they're using that sort of thing keep the design simple and keep it the information in your store easy to consume people can picture really does say a thousand words you can have a picture a gift of a product doing something and it explains what the product does whereas if you had to write the equivalent in text it might take you a couple of paragraphs so where possible try and use icons imagery and gifts over text this is a really important one i'm going to put this in bold actually and underline it because this is something that just people just do not consider at all like when you it's something that consumers do subconsciously as well probably something you do subconsciously too so think about the last time you bought something online there's certain things about that type of product or that item that you want to know before you're willing to commit to it otherwise you wouldn't buy it so for example if you're selling if we use nano cast as an example um half of the comments maybe even more than half the comments on facebook where people asking things about the products because they probably can't find the answer in the video or find the answer on the website and people who aren't sure about something don't spend money so you need to make sure that you kind of put yourself into consumers mind think about the sorts of questions they would want answering or sort of information about products they'd want to know and make sure you answer every single one because again confused consumers don't buy anything so if you're selling a battery-powered product how long does it take to charge how big is the battery how long does the battery last and then you have the things that aren't actually about the products and then more about the business so how much is shipping is it free if it isn't then how do i get free shipping is there a discount code i can use when will the product arrive what is the returns information what's the shipping information you need to make all of these things crystal clear on your website and easily accessible don't try and hide anything because somebody who goes looking for a piece of information is actually a good thing because they wouldn't be looking for that piece of information unless they were serious about potentially making a purchase and if they can't find that information they're going to leave because there's that confusion and uncertainty about shopping with you last but certainly not least is feature people everywhere use a tool called placeit.net there's mock models on there with different t-shirts in different scenes and settings get people on your website use influencers use yourself use friends and family people want to buy from businesses where they know there's a real person behind it scam stores do not have people behind it because when you start showing faces and real people and having contact information and that sort of thing all of a sudden the business becomes a lot more trackable and if you are a legitimate business then of course you're trackable because you're not scamming people and therefore you don't care if you're trackable and you don't care if people know who you are so try and feature people as much as possible across your website move on to supplier then so stay away from aliexpress if possible they're not a specific drop shipping supplier you can use them i have seen i used to use them to be fair i've seen people use them in the past but your life will be a lot easier your business will be so which less stressable your business will be a lot less stressful if you use a proper agent like cj drop shipping or bs drop shipping or send drop however it may be look around put a simple google search in you'll be inundated with the different amount of drop shipping suppliers and agents out there yes it might take you a week or two to talk to all of them and get the quotations will get the numbers and shipping times and all of that down just record it all and again if you're in this for the right reasons and you're serious about making this then spending a week or two to speak to 20 or 30 different agents and suppliers is not a big deal point number three ideally look for an agent however there's a bit more work a lot of trust comes into this obviously so this can wait until you're established but if you know of one or if you can even better get a recommendation then it's always a good route to go down last but not least longer than two weeks delivery is a no-go anything under that is definitely manageable at least for the drop shipping stages again going back to that proof concept idea anything less than two weeks is more than manageable and more than works as well for you to validate that the business idea works before them moving and progressing on to private labeling so on and so forth so just make sure whoever you're speaking to they can guarantee a delivery of 90% of parcels plus under that two week mark let's move on to marketing then the beast that is marketing it's a bit of a jungle very overwhelming for people just starting out when you create a business manager and you've got all the different tabs and data sets and pixels and security center and ad manager and people pages Instagram it can be domain verification and all these weird complex terms it can be a bit of a stressful place or overwhelming place to be so here's some kind of like generic guidelines to kind of keep you on track and make sure you're focusing your time and attention in the right places ultimately though the key to kind of take away from anything is that in the beginning you are going to be a newbie you are going to be overwhelmed if this is something you want to do you're just going to have to keep investing more and more time into learning your craft into learning what you're doing in order to get over it a number one to start go cheap when starting out to test the waters so think of like if you were starting a new hobby if you were taking up golf would you go out there and buy brand new Callaway drivers and woods brand new Tarlist irons brand new wedges there's got a camera and putter and a brand new Tarlist bag and spend three or four grand you probably wouldn't write you probably go for a cheap starter set for three or four hundred quid see if you actually enjoy the game see if you can get better at the game and then when you do slowly kind of expand in your bag and buying more expensive clubs Facebook is exactly the same thing don't go and spend more than 50 quid or 100 quid on an ad creative don't go and spend more than 10 pounds a day per ad set start out super cheap see what happens dip your toes in see if you can get the odd purchase look at the numbers try and get your head around what CTR and CPC and all that sort of thing means try and get your head around how you influence those numbers and what those numbers actually reflect and mean i'll give you kind of like the most important things today but ultimately like you could write a book you could write a film you could write a course solely just on social media marketing once you do get some good results then so you've had a couple of purchases and the data looks pretty good these are some very rough ballpark numbers by the way so two percent CTR that is a link CTR less than one dollar click so CPC and you've had the odd purchase of course then reinvest in your business so instead of going 0 to 100 go 0 to 10 see if things start working out see if there's potential and when there is that potential invest more double down on what's working as for platforms i like facebook for consistency there are still the odd issues with ads getting rejected for no reason banned ad accounts that sort of thing but i keep telling people like if you haven't done anything seriously wrong more often than not it's going to be a facebook mistake and you'll get everything back within 24 hours so sometimes you do have to be a bit patient with them but when it comes to a consistent results and relying on kind of what's going to come the next day then i really like facebook for that when it comes to the strongest type of buyers so this can almost like link back to the product that you select for me females 40 plus the strongest buyers like i've tried selling products to males before i used to sell quite a lot of cycling gear actually and that worked to be fair but the strength of the consumer when it comes to females over the age of 40 they're just the strongest buyers it's just a fact so when you're doing your product research maybe to keep that in the back of your mind just think would a female over the age of 40 want to buy this product next test five to ten variations of creatives when i've started a new ad account especially i find this incredibly important the difference between using like small money changes can make a big impact it can be an emoji in a different place it can be a certain wording the first two lines so there's a famous saying in marketing where 80 cents of your dollar is spent on the first two lines so your primary text and the top of that facebook ad try and get as many keywords and buzzwords in there so for example if you're selling a toy for large dogs like german shepherds because they're strong biters they are the keywords i just mentioned there you want in those first two lines so it could be a testimonial from somebody who says my german shepherd is a strong chewer every toy i've ever tried in the past is no good after two weeks except for this one or something along those lines right just get the keywords get the buzzwords the words that are going to resonate with your audience get them in the first two lines of the primary text and get them in the first few seconds of your video had creative as well get five or ten variations of different creatives going or assign an equal budget i should say assign an equal budget to each of the creatives so each budget each creative has its fair chance of success it's an equal test you can see what works and then again double down on the best performing creative the last tip i'm going to leave you with is include people speaking it is 100 a fact if you have one video that just has a voice over and one video that has somebody on screen talking the person on screen where you can see their emotions you can see their mouth moving you can see them moving on camera talking about the product 100% it holds people's attention a lot more than just having a voice over you can combine it too so there's a change of frame every kind of two or three seconds to again kind of reset somebody's attention span but if you're going to go for one or the other make sure you try and get somebody on camera talking and speaking about the product and better yet get subtitles of what they are saying and get the subtitles to appear one word at the time in timing with what the person is saying because every time that subtitle comes on the screen it resets somebody's attention and focus it gets them to look at what's changing and it keeps them invested and without even thinking about it just watching more of your creative and of course the more of your creative they watch the more features and benefits of the product they will see and therefore the more likely you are to be interested click your link go and buy the product and so with that being said guys that is my four step process my naught to 10k beginner strategy i covered a lot in this video it's kind of like a mini course hopefully you guys enjoyed it if you would like some help some hand holding walking through this you might have heard me mention a couple of times in the video that i worked one to one with people check out the links in the video description below there's a link you can use to book in a call with me so we can have a chat and i can get to know you see where you're at with your business see where you want to be in two or three months time and see if i can be the person to help you get there that sounds good to you make sure you check out the links don't forget to like and subscribe and i'll see you in the next one cheers


Sex differences have been observed in adverse drug reactions, ADRs.  Lithium was found to cause more thyroid dysfunction in women, while amosulpride-induced prolactin increase was more pronounced in women than in men. Serious ADRs such as clozapine-induced neutropenia, and simvastatin-slash-adervastatin-related abnormal liver function tests were more common in men. These findings suggest that sex should be considered when prescribing certain medications, as some may pose greater risks to women than men.

Hi everyone, I'm Mammy Ratsim Bazafi and today I will talk about the design of a high-performance multi-fledding framework. So the multi-fledding framework is implemented in NIM, but everything I'm talking about is something that you can also do in C, Rust, AIDA, any kind of language. My hope is that after that talk, you will be able to implement your own multi-fledding framework in a weekend. So let's see how we can do that. So a bit of things about myself. I've been using NIM for three years now and I'm a blockchain developer during the day and high-performance computing developer and also data scientist during the night. You have my Twitter and my GitHub accounts. So how did I start doing a multi-fledding framework from scratch? Three years ago, I discovered NIM. I wanted to do some high-performance computing in NIM and I had two-fledding models I could use. One is OpenMP because NIM compiles to C and you can add OpenMP annotation to NIM. So that makes it very easy to do parallel for loops. The second-fledding model is a simple thread pool with just a spawn and a sync statement. And so I used OpenMP for starter on my multi-fledding run on my high-performance computing and tensile library. But a year ago, I was dissatisfied with lots of the internal, including the threading. So I started to re-implement everything from scratch. And the goal today is, as I said, end up with multi-fledding runtime that you can implement in a weekend. And to go there, we need to first understand the design space, second, understand what are hardware and software multi-fledding. So definitions, these cases, parallel API and the sources of overhead, how to benchmark them and the design constraints that those bring. So first thing, understanding the design space. One thing that you hear often is that concurrency is not parallelism. So here you have a coffee machine, or here two coffee machines. Concurrency is the ability of the hardware, no, sorry, of the OS or the scheduler to switch between, to interleave two threads of execution on one single resources. In case of parallel runtime, you have two threads of execution and two resources. Another thing that you will see a lot is probably 1-1-fledding, N-1-fledding, M-N-fledding. So this is about on the left, the number of application threads, and on the right of hardware threads. And so this is something that is often seen at the OS level. So when you talk about very old OS, they had sometimes N-1-fledding or 1-1-fledding. But this is something that also happens at the language or the runtime level. It's just definitions and we won't see it again. So the problem is for multi-fledding runtime, how to schedule N tasks on N hardware threads. And another thing on the design space is latency versus throughput. So latency is for a single task, if you have like N tasks, and you have a single task, maybe you want the single task to be fair, like first in, first out. So this is what happened when you have multiple clients, a single server, and you are supposed to serve all of our clients, let's say a web page, and you don't want to, clients, to spend an hour waiting until everyone else is done or for video decoding. If you have multiple frames and you need each frame to be processed one after the other, you need some fairness. So this is optimizing for latency. The other thing is optimizing for throughput. For example, in scientific simulations, you don't care about the single computation. You want everything, the whole work package to be done as fast as possible. So even if the first task waits for one week, as long as everything is done as fast as possible, that's fine. Another design axis is cooperative versus preemptive. Preemptive threading, you probably heard about coroutines, fibers, green threads, first class continuations in a scheme, for example. The characteristic is that those are lightweight, and you cannot use hardware threads for those. Second, preemptive threading, also P threads used in open MP, TBB, or silk, if you dive into preemptive threading runtimes. Those are scheduled by the OS, they have easier context switches, and you need synchronization primitives because those are real threads, let's say. So synchronization primitives can be locks, atomics, and also things that are less known like transactional memory or message passing. And you have IO tasks and CPU tasks. So IO tasks, like you're waiting for network connections or files, and you create tasks. So those are usually latency optimized and implemented via async await, while CPU tasks they are throughput optimized, and the terms that are used usually are spawn and sync. So there is a parallel, let's say, between both API. It shows that the internals are completely different, and the requirements are different, the skills for maintenance are different, the OS API are completely different as well. So for the talk, I will focus on CPU tasks optimized for throughput on preemptive scheduling, so on multiple hardware threads. So now, we have a bit of definitions, and let's see the different forms of multi-threading that exists. At a hardware level, we have four kinds, there are many more, but the four main kinds are ILP, instruction level parallelism. So hardware, let's say, a CPU ARM or X86 has multiple execution ports. For example, to do an addition, you have two or three ports available, they are called 0, 5, 6, something like this. And you can schedule multiple additions in parallel, that's done by the processor, as long as one execution port is free. SIMD, single instruction multiple data. So if you heard about SSE, AVAX, or ARM Neon, for example, those are also called vector instructions, you have an addition, and it works on four floating points at the same time. SIMD, single instruction multiple thread. So those are GPUs, basically, and on GPU, you have 32 threads for NVIDIA GPU, those are called a warp, and they have to do the exact same instructions. And for example, if you do an ETH branch on the GPU, it will execute both branches. And the last one, simultaneous multi-threading, also called in Intel Speak hyper-threading, it's a way to use all the execution ports by having logical threads sharing the same execution resources, same memory bandwidth, because it's usually quite hard to use all execution ports at the same time. And it's not always two sibling cores that are used in hyper-threading. If you use Xeon Phi, it's four sibling cores that you have. Now, let's talk about the form of parallelism that you might want to implement or support in your runtime. First one, data parallelism. Easy, it's just a parallel for loop. If you use the OpenMP, or if you used on C++, Intel TBB, Parallel 4, or on Rust, Rayon, that's exactly that. It's a same instruction multiple data. Use cases, scientific computing, you have vectors, matrices. You do a for loop on all data. Challenges, how to support nested parallelism. For example, OpenMP doesn't really support nested parallelism. And there are other load balancing challenges. So it might seem surprising, but splitting a loop for multithreading is actually complex. Because if you split before entering the loop, maybe you might try to split a loop in 10, even though the loop is super small and you don't need to split it. If you split, well, I won't enter into detail, but you have three splitting strategies that you can research if you want to implement data parallelism. The main one, task parallelism. So this is spawn and sync. It's basically a function call that may or may not be executed on another hardware phrase. And the may or may not is managed by the scheduling runtime. An example, Intel TBB or OpenMP tasks since OpenMP version 3.0. Use cases, anywhere you want a parallel function. For example, parallel 3 algorithm, like depth first or breadth first search, divide and conquer algorithm. And there are multiple challenges. The API, now most of the runtimes are using features in Weave and in NIM. I'm using FlowVar to distinguish from IO tasks that are using features and CPU tasks that are using FlowVar. It's just a name. Over-challenge, synchronization, scheduling overhead, and memory management because you need to save tasks. Okay, five minutes left. Let's go fast. We have another kind of thing, data flow parallelism. Four names, pipeline, graph, stream, data driven parallelism. The main thing is you can express dependencies between tasks like dependency in, dependency out, and in out closes. Parallel API. You have Async, launch a thread that may be parallelized, await, await for a result. So this is for IO tasks and we can use a spawn sync for multi-threaded tasks. Data parallelism, I talked about four loops. Data flow parallelism, there is no established API, but you can use either declarative one where you create a flow graph explicitly before entering a parallel section or you can pass a handle like a promise to set a task ready or not. Species of overhead and implementation details. You have scheduling overhead because switching between tasks is costly and switching between a kernel when you need to create threads or destroy them is costly as well. Easy solution, use a thread pool. Memory overhead. You might, if you use the Fibonacci tasks, Fibonacci 40 for example, we create two at the power of 40 tasks, meaning trillions of tasks, and you need to deal with memory management when there is nothing to do. So you will need some clever memory management with memory pools to deal with that. And also on memory pools, sometimes you have one thread that produces all the tasks and an overhead that consumes everything and you cannot use caching in that case. So you need to handle that as well. I'm skipping on the CAC2 stack and segmented stacks, but it's a complex research and a go and rust tried and failed and abandoned CAC2 stacks. And the new GCC from three months ago also is a stack less to avoid CAC2 stack issues. Load balancing, the meat of the talk, let's say. The issue with simple thread pool is that usually you have one global task queue, you dispatch a task to a ready thread, but you have a contention issue because this task queue is, if you have 10 threads that are asking, give me a task, give me a task, give me a task, the task queue will be very busy and the best way to scale a parallel program is to share nothing. This is Andal's law and it tells you that if you have 95% of your program that is parallel, the maximum speed up that you can get is only 20. So you need to avoid serial parts as much as possible. And serial sources of serializations are the single task queue. If you have a memory pool that is also global and you need to distribute everything on multiple threads. So one way to do that is to have work stealing. You have multiple worker, one IP, everyone has his own task queue. It push and pop from one end of the queue and when you run out of tasks, it gets from another worker a task. This way the synchronization happens only if the queue is empty. This is a summary of the things related to work stealing and there is mathematical proof of optimality, asymptoptical optimality, which is why almost everyone except Julia is using work stealing. Julia is using something called parallel depth first scheduling. It's also proven optimal, but it has a different performance profile and hover profile. It's still in development because it was released in September and you can look into it. One thing that you should look into are memory models. I've given the talk from Herb Sutter inside. If you want to use relaxed atomics, acquire release, it's very important to watch it because it's written nowhere. I'm skipping on load balancing. You have multiple strategies to share tasks, still one, still half, adaptive, but I don't have the time to go inside. So the end, work stealing in a run time, in a weekend, you need a task data structure with a function pointer and a blob for task input or a closure. You need a start, stop, step for data parallelism if you want to express a for loop. Have next field for intrusive queues and dequeues, a future pointer to send the result back to the caller. A work stealing dequeue with a head tail field and push first, pop first and still last operations. For the API, you need to create your thread pool, exit to shut it down and spawn sync to create tasks and retrieve the result. Some references, those are also on the FOSDEM website, and that's it. I think for one question or two, and the next speaker should come up as soon as possible. Yes. Sorry? Yes. Currently, my run time is actually at least as fast or faster than any of the run times. I have an MP, TBB, Rayon, HPX, Julia, so really, if you have a challenge on benchmark speed, I'm ready to take it.


Hello and welcome back. I'm EvilRabbit. We are staring at the start gate of an ESDA track here on a set of Corsa and a car It is not familiar to you guys. That's because we're starting a new series here on the channel driver spotlight Well, I'm going to take pro cars from some of the major competitions with permission from the owners such as ESDA, VDC, DCGP, EDC and all of that including driftmasters and going to be doing basically a review on These individual pro cars for that these guys have built and are running So make sure you guys follow me and all social media all which are found in the description box below So the first car up is that of I tandem adi I competed with adi back when I was an SSR on force motorsport 7 He has this very awesome S15 this isn't his actual full livery. He's got a pretty pretty dull looking livery free SDA here in a set of Corsa So it's a pretty awesome S15. It sounds amazing. Looks amazing. It's got underbodies. Definitely appreciate that and It's been some big old fireballs From the back end of that car so a big thank you to adi may forgive me access to this car to Take it for a rip for the first episode here on you know driver spotlight What better place do it than an official ESDA track here at Daytona? So We're gonna go for a rip. I've heard from him that this car has no lift shift So we're gonna test that out today.  There's a pre mantis on the dash All right, that's pretty sweet big old fireballs from the back of this S15 so It's definitely a very powerful car a thousand some horsepower four gears We're gonna go from the back of the back stretch real quick And we're gonna go full send on it and go on a straight line and see you know Kind of a speed we can get and we're also gonna test out the snow lift shift so I am using clutch right now, but From what adi was telling me we don't have to to upshift So, you know, we're gonna go test this theory out so We're gonna go full send here and then we're gonna run it on the track and see what we can do Definitely like the fans moving in the back second third fourth no clutch still losing tires boy, oh, yeah this car accelerates It's definitely losing traction. Of course, a thousand some horsepower in this turbo three, you know s15. It's I think it's on three 25s. I could be mistaken on the tire size. I'll have to check that but So we're gonna heat up our tires a little bit that no lift shift is crazy, but it kind of stays in boost obviously and Lose this traction. So we made run a couple runs in You know standard shifting and not no lift shift and then try no lift shift entry whoo this car definitely very Powerful so we'll see if we can handle this car was gonna hopefully we don't you know disrespect adi's car a little bit too much I'm gonna go in third kick it in Oh, I haven't driven this track in a minute We're definitely off that clip kind of clutch kicking a little bit the quick snap kind of got me off The start and I think I need to increase my feedback because I'm very low feedback right now And it feels very light so we're gonna adjust my feedback settings here on my wheel Yeah, we're 56 So let's go up to 80 We're at 56 for feedback. So we can go up to 80 So first impressions on adi's car. I love the styling of it. I love the fans in the back You know for the rear mounted radiators car definitely sounds good. I appreciate the underbodies because well I like them so off the rip the setup was actually quite good I didn't have to do much anything all I do is I think lower the tire pressure a little bit And adjust braking bias for my personal preference, but otherwise that That was a pretty solid fast run and uh quite impressed with how that reacted These are definitely a lot twitchier than say my street cars because competition cars are very twitchy and very snapped angle so some you have to get used to but uh I think for a first rip on this car. It was not a bad run whatsoever. Yep, that's much better on the feedback Up at 85 Let's make sure I do not have any DRI on DRI is off force feedback is at 80 sensitivity is 900 degrees Actually, we'll put it's a authentic Run number two We're still not gonna try no lift shifts. I'm still still something new to me that I might have to figure out how to use Oh, no, sorry eddie Sorry eddie. We kind of uh Pissed the car into the wall. I should have stayed a little bit more in power So like I said, these cars are definitely very different Then the street cars and everything competition cars are very quick to angle and things of that nature And you gotta have a very dialed tune. Otherwise the car will catch you so I like how his car matches my wheel You know the purple and coloring and stuff like that pickle fireballs. Let's uh, let's go Oh Gonna try to stretch this out quick handbrake grab stretch it out Not the perfect line kind of sloppy wouldn't be a perfect, you know qualifying run, but you know Definitely a new car to me but If this thing gets down not gonna lie eddie's definitely done a lot of good work with this car I know he's working with some other people with deliveries and things of that nature. It's definitely a solid car So let's take it to a track that I know very well If you guys can guess what that track is and you know where we're going. Let's go get to it So, you know, we could not leave without testing this car at my favorite fd track. That is urwindale You guys know, I love this track. We did Drop the gear ratio down and hopes that we can Utilize fourth and possibly this no lift ship feature Oh my I think we may be able to actually utilize fourth now and the no lift shift So make sure you guys follow me on social media. I'll just found the description box below and also a big Thank you guys and maddie for hitting me up With this car for the beginning of this series. So if you guys want to see more of this Let me know down in the comments down below if you have a pro car that you compete in In some of these major computations. Let me know hit me up on discord We can possibly get a driver's showcase on your car. So let's go after urwindale I tell you maddie's s15 quick snap the angle Probably could have lowered the gears a little bit more Definitely should not have grabbed you break there, but Down in the third actually that no lift shifting is quite nice and uh Not a bad run So it looks like we can utilize third on the bank too. So we're gonna try and rip Third gear on the bank I've already taken away 10 percent of our tires So let's go for another run here I'm actually having a lot of fun doing this driving other people's comp cars Throw it in a little bit lower on the banks. I don't want to be see if we can sauce it up there Massage it up a little bit Should not be pulling you break in that transition, but We got this a left foot break to bring it down Car handles tremendously well Almost taking that wall Try and run this inner wall Once again, a big thank you to adi for allowing me the use of his pro comp car for esda so I hope you guys enjoyed this episode if you guys want to see more Let me know in the comments. We are going to do one final run in adi's car We're down to 78 tires 10 percent of tires per run. These falcon 615s are definitely getting chewy. So let's uh Let's go full send Try and get higher on the bank though Kind of a snap angle No handbrake there. That's what we needed A little handbrake there. Oh, yeah, this is this is a much better run I think this is a perfect run to end this episode off on So as always I thank you guys for coming back and watching almost taking out that wall. I'm evil rabbit I'll see you guys on the track


Day the Dead. Classic, classic zombie movie. But this isn't that, this is Bloodline. Ooh, that's a hot mug, guys. Really hope I don't have anything in my teeth now. Hey guys, doing another movie suggestion here from the list that I asked you guys about. I should have been a little bit more specific, but obviously you guys wouldn't know. A lot of the suggestions so far I can't watch because they're not available on Canadian Netflix, Crave, Amazon Video. Hopefully maybe I can find alternative motives. If you're wondering why I haven't done some, it's because I can't find them. And one of the suggestions with Giorgio Romero's Day of the Dead, fantastic zombie movie, has one of the greatest rips in zombie movie history. Most disgusting scene, but just so good. This movie is just disgustingly bad. This is a remake, but the only thing it really keeps in common with it is a female main character. It's at a military base and they are using a zombie as a test subject. Everything else is different.  And that's not just the story. The story is garbage, but the acting is horrible. The lighting is terrible. The sound is bizarrely terrible. There's conversations between two different characters and one will sound normal, will sound correct like it's properly mixed. It's been worked. And then the other one sounds like it was filmed in a completely different environment, completely different setting. Not the same place at all. It's either horrible ADR or horrible mixing, but the audio is just jarringly bad in this movie. The gore effects are laughable. There's maybe one really good effect of like this de-glap-otated zombie face, but the rest of it is just blood squibs going... The first kill you see is a guy pulled down the stairs down into a subway and all of a sudden this massive mist of blood just blasts up through the stairways. You don't see the guy being eaten.  Cause you know, that's how blood exits human bodies when we bite each other.  This is what would happen if the coronavirus turned into a zombie virus and the only people who lived are those from Florida and the other dum-dums. Just so much stupidity is in this movie that it's baffling. And the concept, the whole idea of what they're trying to do is they're trying to make a vaccine, a cure for the bites.  And it's just so funny considering how many scientists, how many officials, how much money is being put into trying to make a vaccine for COVID-19 right now. And one woman can make a vaccine. In like days too, it takes a place over a few days. The movie's just got no rhythm. It's very boring. And when it's not boring, it's laughably bad. You could watch this as like a drinking movie. This would have actually been a really good drunk review because this is a bad movie. This is a terrible, terrible movie, but it's funny to laugh at because of how bad it is. There's a lot of really shitty zombie movies out there. Is this one of the worst ones? No, there are some that are even worse than this. But this is pretty high up there. It's premium garbage. This movie didn't even get the one best part right of Day of the Dead, the original, is when the asshole military commander gets ripped in half. There's nothing that's on that same level.  Do not watch it, zero out of seven. Anyways guys, that's all for me. I hope you enjoyed this review. If you did leave a like, and if you're interested in more, subscribe. Otherwise, see you guys next time. Thanks for watching the video. My name is Knitz, and you might remember me from the animated cult classic TV show, Undergrads. It's been a while, but I'm happy to say the click is finally getting back together in an all new movie, thanks to a successful Kickstarter campaign. But we are still asking for your support. To see any and all updates about the upcoming Undergrads movie, be sure to check out and like the Bring Back Undergrads Facebook page. And with any luck, we'll see you guys soon.


Hey friends today We're gonna give you a look at what a drive-thru haunted attraction is like here in Orlando We are all upset that Halloween Horror Nights has been cancelled So there's many more haunted attractions in the local area and we're here at Boggy Creek And we're gonna be checking out the scream and stream Drive-thru haunted attraction now this doesn't officially open until September 25th But we were invited out to get a sneak peek of what it's like or what it's gonna be like because there's a lot of questions And we need to find out so Let's go do this The reason that they're doing drive-thru attractions is because it's very easy to actually Socially distance when you're in your own car, but it brings a lot of questions like how is it possible? Are they gonna be able to scare you in your own car once if you slam on the gas or slam on the brakes? There's a lot of things hopefully we'll get some answers to those today and just generally see what it's gonna be like because I Think it's a cool concept Because it is super dark out. It's gonna be hard to see but we've got flashlights And I'm with Jackie That kind of rhymed it in it We are gonna start actually getting the grand tour of everything that they have to offer This location alone is gonna have three different attractions Obviously it being an airboat attraction They're gonna have a haunted airboat attraction Then they're gonna have the drive-thru haunted attraction and then also a kid-friendly trick-or-treat with the proper safety precautions So I really think that this is gonna be a very fun and amazing event. I'm very excited While you're waiting to do your haunted attraction that you choose they have a nice area set up where you're gonna be able to just hang out They're gonna have a bar here and then some frightful entertainment and it's just gonna be a common area where you can actually just relax The cool thing is when it comes to like drive-thru Actual attractions. I've always remembered like during Christmas time I would go to like Mayock Park and I would partake in a drive-thru attraction to look at all the lights that they had like the Christmas decorations And that's how they're kind of doing this here itself Except for as you're driving through there's gonna be different scenes that are gonna, you know, hopefully scare you This area is a perfect place to actually have an entertainment as you can see It's kind of spooky already. Look at this. It reminds you of like a little cabin on a swamp But this is gonna be the entertainment stage Wow It's starting to get a little bit dark out Luckily Lyle who is the entertainment director is giving us the tour around because I wouldn't be able to see anything All of the attractions are actually gonna be based off of a story the actual drive Through attraction is gonna be based off of a drive-in like a movie drive-in Storyline and I think that's an awesome concept because I don't know circle drive-ins and stuff like that Mix that in with an actual haunted attraction. That's good stuff They also are gonna have dining options and the dining options are gonna be some of your favorite Haunted attraction food when I say haunted attraction. I mean Halloween horror night food. They're gonna have pizza fries They're gonna have twisted taters. I think that's really cool, and it's actually gonna be right here Nice little spot. We were gonna start our actual drive-thru attraction Well the mock attraction because we're just gonna get a sneak peek at it but for you to understand this is how you're actually gonna enter into the drive-thru attraction and You're gonna come through here, and it's gonna be four cars at a time and underneath that white covered area there They're gonna go over all the different rules and safety things and one of the most important things is is There's a three mile per hour speed limit Which is gonna give you plenty of time to be able to enjoy and actually see all the cool things that they have Now that we're actually in the car. You can hear kind of some creepy music Which is actually themed to the drive itself So it's actually linked up to a radio station and you're gonna be able to actually get a little bit scary inside the car As well outside the car You can roll down your windows if you like as long as you're wearing your mask And now we're gonna start getting into some of the scenes, but we're not gonna show it all Not gonna show any of it that actually spoils it for you And it's actually really creepy out here already. Look at the road ahead A car that's out of the car on the side of the road where you'll be offered a psychedelic beverage As you're actually driving along you can see they have the up lighting on these trees And it's just so awesome looking isn't it? And one of the biggest things that we have to wonder is How do you know when to stop because it is basically on a red light and green light So red for stop and that's when a scene is actually gonna take place And this is how they're gonna control the flow of traffic So people aren't running into each other when you see red you stop you take part in the scene And then when it lights green you proceed to the next scene We're gonna show you what it looks like for a scene to take place. We have some great performers 14 hours, and it's gonna be so good And to show you what the daytime trick-or-treating drive-through is like this is how they're actually gonna safely Supply candy to you in the vehicle without actually coming into the six feet mark and watch this How smart is this so part of our Our aspect is we're going to have acrylic balls off-site that are preloaded with candy and a sanitized environment Everybody's gonna be wearing Gloves and masks whenever they do this and I've got some starbursts for proof of concept essentially This it's socially distant it's safe like this is this is great a starburst The whole actual drive-through attraction is about 1.3 miles and it takes about 25 minutes in total and you pay actually by the car So how many people are in the car? That's what you pay for We're standing outside in one of the areas and they're doing some promotional footage and some different photos And we're lucky that we get to like see a little bit of it Just taking a look at the actual track Well the actual road that you're gonna be driving for the drive-through Experience and it is kind of creepy out here.  It's gonna be maintained at three miles per hour, and it's gonna be observed And like we explained before with the whole red light green light system All of the scenes are gonna take place at the red light when the cars are stopped so you're gonna be well aware that something's about to happen when the light turns red and It's more or less more theatrical in all the different areas So it's very well planned and it's gonna be very visionary and there's gonna be great scenes. I'm really excited for this Now we are back out front I was only able to show you what I could without spoiling anything But the main thing I wanted to know is how they were gonna control the traffic and control people in their own cars And we got that answer today They're gonna use the ratting green light system along with some people that are gonna be manually directing traffic Three miles per hour, and they're only gonna let four cars in at certain points So it's actually gonna be very easy to make that happen and all of the scare scenes are gonna happen at the red light So the car is gonna be stopped when anyone approaches the vehicle now for the haunted airboat attraction that's gonna be more on a Like nature side they're gonna tell scary stories. They're not gonna have any scare actors You're gonna see alligators obviously and it's just gonna be a creepy experience But you can come out here take a nighttime haunted airboat ride Or you can do a daytime kitty trick or treating and also the new drive through haunted attraction I think that's fantastic Anyhoo's that's gonna do it for me today. I hope you guys enjoyed this video I enjoyed making it. I'm very excited to be here and check it out and also check out all of the local haunted attractions here in Orlando Just because I'm gonna be so sad of missing Halloween Horror Nights gotta fill that void somehow gotta fill it So we'll see you next time. Bye


Well obviously I believe it's a lot of strength we can bring to the table. I think bathroom has been around for many many years so call it a collective memory of hundreds, thousands of cases we had to go through for good or worse. Truly educating a large team of very able colleagues, very well trained colleagues, experience which was truly hardened by crisis management and of course good times as well based on a very profound skill set of extremely well trained and well motivated people. That of course is not unique in Europe but that is certainly a strength we can bring to the table. We have very strong departments on specialized items just picking an example like modeling, know-how, quantitative modeling and issues like that. I think it's the breadth of experience and skill sets which puts us into a special responsibility to provide resources and know-how into a grander European orchestra in a way.


Welcome back to fail Colorado the u.s. Open of snowboarding presented by Burton the field is stacked so many young riders coming up Now watch this this is gonna be the biggest air you've seen all day Going at least 25 feet out of the pipe on his first hit and following it up with back to back double quarks If he stays on his feet right now this score will be in the 90s, and there's the double McTwist 1260 we didn't even see that in the semi-finals Frontside 7 20 tail grab and Sean white just beat this half-bite into submission 25 hitting me score is huge 95.6 for Sean white the pace has officially been set here in Vale at the men's Finals Sean white is here to win. Let's see. He's about to blast his first hit. That's for sure Man with the staggering oh Backside there to open up Frontside double cork 1080 followed by the cabs well double Frontside 540 There's the backside double cork 12 and the front side nine Sean white that camp 14 in the middle of that the centerpiece Unbelievable that kid has not gone anywhere that's huge from sure what some 22.7 coming in hot Look at that pre Ali landing high on that transition wall Starting things off with a massive backside air grabbing method into the frontside 1080 to the moon And then the cab double 10 Frontside 900 Backside 1260 from Raibu Katayama, and then the front double 1260 Raibu Katayama just put every competitor at the US Open Officially on notice that was the best run. I have seen him do all season long setting yes standard Wow Point for I think we're gonna see Scotty's a game right here I think we're gonna see a put it all out on the line right here run one US Open. Let's see this Wow switch back double cork 1080 into the backside double cork 1260. Oh, he's going for it Big frontside 1080 with the nose grab Into the cab double cork 1080 going to the moon Finishing it off of the frontside double cork 1260 and yep He did it. Wow. He did it 82 even Dropping switch switch McTwist off the tombstone Into the Hawken flip. Although that was good info. We gave us after his first run It's a little bit more of a butter right then it is a inverted switch frontside seven Coming in switch y'all chair going for that cab double cork 1080 Into the frontside double cork 12 This is Scotty James last chance To try to go back to back at the US Open switch backside 900 after that frontside invert now coming in switch This is the equalizer Scotty used to be dominant with that switch back 12 But now you tow has learned that into the switch frontside 1080 double cork Scotty James It doesn't get closer than this So what 93 just the way he rides the transition and lands at the top every time is Mind-blowing he goes massive. I'm really interested to see if he's gonna step it up or cleans up So starting things off with the McTwist and that is crazy the way he's landing at the edge of that transition Yeah, the alley you back rodeo will we see the frontside 14 right here? We will Unbelievable into the cab 12 Into the switch backside double cork 12 What is happening right now? 97 are you 18 years old coming out of Yokohama, Japan?


What they gonna do with me now?  These bitches be fuckin', these bitches be wild Hey yo Tatsy, we know you a thot Alright so hey guys, we got a new episode of Talk of the Town Today we have a special guest, Sugar Hill God, nigga, what's going on? I know who this is, bro So for people that don't know, or it's unfamiliar with Sugar Hill Tell us like what that's like, where that's at How would you explain that?  So like how did, so everybody know you kind of like met growing up? Like y'all been to each other? Like who? Like you and Edyne and D Yeah that's my baby And um, is there more artists coming from Sugar Hill or?    Like four, five months ago Six, five months ago So four, five, six months ago So with the move look song though How did the idea of that song come about?  What would that mean?   Are you going to give us a project soon?
