Zanimljiv program. Nije los ni kao stress test. U paketu dolaze i 32-bit i 64-bit verazije sa podrskom za SSE3 i SSE4.1. Multithreading se podrazumeva.

The first scalable multi-threaded Pi-benchmark for multi-core systems...

Against the Big Guns...
Faster than SuperPi on single-core...
Faster than PiFast 4.3 on dual-core...
Faster than QuickPi 4.5 on quad-core...
