yesterday i realized that SuperPI is the slowest PI calculating program i know.. SuperPI calculates 8 million digits in 3.5 mins, and this other program in 25 seconds!!

and this other program can also calculate bigger amounths.. just finished calculating 1 000 000 000 digits with it, taking about 3 hours.. so i wonder if theres any faster programs

oh yeah.. this program is PiFast 4.1

Code:
Program : PiFast version 4.1
Computation of 1000000000 digits of Pi
Method used : Chudnovsky
Size of FFT : 8192 K
Physical memory used : ~ 395360 K
Disk memory used : ~ 4291.53 Meg
edit:
oh yeah.. this app is Single-Threaded.. i wonder if theres Multi-Threaded apps?
