y-cruncher: Multi-Threaded Pi-Benchmark for Multi-Core Systems... (official thread)

Latest Version: v0.6.5.9442

Now with support for XOP and AVX2. Backward-compatibility is maintained for older processors.

The benchmark is also available for 64-bit Linux.

What is y-cruncher?

y-cruncher is (yet another) program that computes Pi to millions of digits.

But unlike SuperPi and PiFast:

- y-cruncher is multi-threaded and is capable of using multiple cores.
- y-cruncher is able to use modern instruction sets such as SSE and AVX.

And unlike HyperPi, y-cruncher uses multiple threads to make a single computation faster. (as opposed to running the same computation multiple times)

Because y-cruncher is multi-threaded and uses up-to-date processor features, it can reach speeds and sizes that are unobtainable with older apps:

- A stock
AMD FX-8350can do32M digitsin9.737seconds using y-cruncher. SuperPi requires upwards of 20 minutes.- A
Core i7 4770K @ 4.0 GHzcan do1,000,000,000 digitsin206 seconds.- The same Core i7 equipped with 32GB ram and 8 hard drives can do
100 billion digitsin23 hours.- A dual
Xeon E5-2690W @ 3.5 GHzwith 256GB ram and 22 hard drives can do1 trillion digitsin83 hours.

Likewise, y-cruncher is capable of setting world records for the most digits ever computed:
