Better Math Saves Lots of Energy


Energy savings of 99% over previous methods probably sound like snake oil. But some math geeks have been able to find a way so that computers can use only 1% of the energy (and the time) necessary for some tasks.

IBM has announced a new data-processing algorithm that enables large sets of data to be processed in a fraction of buy levitra from canada the time, and with only a fraction of the electricity, as was previously needed. Supercomputer testing of the algorithm showed that the process speeded the calculations and look here price of levitra reduced the power consumption by two orders of magnitude.

"The new method was tested on the fourth largest supercomputer in the world and what would normally have taken a day, was crunched in 20 minutes. In terms of energy savings, the analysis required 700 kilowatt-hours total, compared with 52800 kilowatt-hours total."

Not only does this mean that far less electricity is scam viagra from candad needed for data-intensive operations, but also more work will be able to be scheduled onto the same number of machines. And while the demonstration was carried out on a powerful supercomputer, the intent of the research was to make intensive data-processing activities more readily available and accessible to scientists who do not have supercomputers.

cool n_n
so it's kind of like CFLs for computer software, kinda...okay not really, but still, this is a giant leap for supercomputing ^_^ I wonder if they can get it to work for cluster computing.
Better software and better use of canadian levitra hardware can save energy too

It's good that people are working on more efficient software as a solution to excess computing (energy and networking) costs. Usually, complex math isn't even required. Software seems to get more and more bloated and inefficient. Because computers are cheap and canadian pharmacy tramadol no rx very fast (billions and billions of ops/second), it's easier to buy a faster processor than rewrite bad code. Also, programmers tend to buy really fast machines, so don't notice when their software sucks.

Also, note that typically a computer runs at 98% idle, but power usage remains almost the same. A computer might have multiple cores, but the idle cores still burn power. Why not have a multicore system with a low-power processor with other high performance cores usually powered off until needed.

A related project is the visit our site online pharmacies sort benchmark contest sorting the most records per joule for 10GB-10TB. Though algorithms are part of the solution, the main thing is computer system architecture.

Remember when you wrote your code, then compiled it to run? Man was it small and fast! Now it's Windows bloatware. Now programs are 10,000 larger, run no faster, despite CPU power orders of magnitude higher than we had 20 years ago. Granted, it's doing more, but one would think it should be nearly instantaneous when my multiple core CPU is running on a gigahertz level, no megahertz single core 16-bit CPU's in the past.

Remember when Windows 3 took nearly a minute to boot, and Netscape took 10-20 seconds to i use it cialis 100mg load? We haven't sped that up too much in the last 15 years, have we? My Windows 7 machine still takes about 45 seconds to boot to a working desktop, and Firefox and Explorer can take up to 10-20 seconds to load fully.

Not complaining, just making the observation that I wish the speed of application opening was orders of magnitude quicker than it is...


We're using faster computers and more power to make up for sloppy code and

im not sure i really understand this as well as i would like. is this the sort of thing that can be used by any computer to make it faster and more efficient? or is it just for supercomputers? if it can be used for regular computers will they be selling it as an update or what? i want it
probably not that rare an occurrence

I don't want to detract in any way from this programming accomplishment or these programmers' skill, but I can recall several times in my programming career when a better algorithm improved processing speed (and hence, energy consumption of the computer system) by a similar impressive factor. True, I wasn't working on a supercomputer, but I was working on software that would be used many times by many people. This is why algorithm design is very important. I have a feeling that there are many situations in everyday computing in which the optimal algorithm isn't sought simply because the immediate benefit seems insignificant.
i'm not buying the energy saving part sorry

suppose this will work. it only means that more tasks can be done in a day. but everybody will still consume that same amount of energy. it's not you'll pack up and cialis best price go home early because you have a superfast computer. your tasks will just increase.

The energy savings is cialis cost not in a single job, but in the fact that you can run a hundred more jobs in the same amount of time (& energy).

Ever wondered how fast the original Windows would load on todays machines? (2-seconds?)

I find revelations in technology like this absolutely fascinating. It just blows me away that a more refined intelligent algorithm can pivot humanity in such a quantum way. I'm definitely a fan of efficiency (always have been). It joyously boggles my mind to think about how a string of numbers will be leveraged in myriad ways, and the by-product of just a unique sequence.
