    1. pi is infinite we cant find all of pi it is iiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiinnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnfffffffffffffffffffffffffffffffffffffffffffffffffffffffffiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiinnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnniiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiitttttttttttttttttttttttttttttttttttttttttttttttteeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeee

    1. Found a few more digits of pi:

      The reason to calculate Pi in with the methods described in the OP is useful for checking if the second attached link really is doing what it is suppose to. Which is calculate a given place in Pi without having to calculate the preceding numbers.

      All of this is useful for the first link that I’ve posted which aims to “compress” files by addressing parts of it’s data into sections of Pi. Which is really cool as the method used to derive your first address list can be further compressed again before storing or sending to a remote server for reconstruction.

      I plan to use these methods in the third link that I posted where I’m also combining Crypto currencies and MPI for ARM CPUs. Which also will work on RPi’s and micro controllers.

      So Pi may be round but it is not without it’s points.

  1. Hmm. Well, I’d heard long ago that you could could create a circle around the visible universe with an error of less than the width of a proton with only X digits of pi, but when I googled, it, I found X = 32, 39, 41, 43, 47, and 50. Well, a bit less than 10 trillion anyway. :}

    1. i remember deducing it as the limit of some equation of the radio of a polygon with the number of faces going to +inf.
      it was just a matter of putting like 10000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000 faces and you get a lot of accuracy in the result

  2. I remember reading an awesome article on the Chudnovsky brothers (think the newyorker linked on wikipedia), it sounded as if their whole house was given over to a supercomputer, it also outlined their various hardships. It would be nice to see an update.

  3. I actually have access to a top 500 computer for supersonic flow analysis, I might be tempted to give this a go. I’m not sure if I should say exactly what computer but I will say it’s got over 1500 xeon 5660 processors and near 20 TB of ram

  4. I have followed Alexander Yee’s work for awhile, and there are some very good reasons that GPUs are not ideal for calculating pi. I think the main reason is memory bandwidth–when you’re multiplying very long numbers, you’re constantly having to go to RAM, and this is far from speedy with current GPUs. Clustering has similar issues, but the main issue with clusters I think is effective multithreading. Alex discusses that too at his website.
