New Multi-Threaded Pi Program - Faster than SuperPi and PiFast

[alicemb]

hi,

The first efficient and scalable Multi-threaded Pi Benchmark:

60x faster than SuperPi on Core i7.
5x faster than PiFast 4.3 on Core i7.
32M Pi in 9.982 seconds on 4.2 GHz Core i7.
10m Pi in 2.996 seconds on 4.2 GHz Core i7.
1 billion digits in 8 minutes on 4.2 GHz Core i7.

hmm...



here a little sample of pi x64 sse3 chudnovsky, but i dont push/optimize it more (means: will not use it in MaxxPI² / www.maxxpi.net),
because it will only perform on intels that much and this is a *nogo* for comparative Benchmarks, but for getting WR it's ok.

nice work, Alex!
