y-cruncher

y-cruncher - A Multi-Threaded Pi-Program

*Computes Pi and other constants. *Capable of computing trillions of digits of Pi (among other constants). *Faster than PiFast 4.3 and QuickPi 4.5 when two or more cores are present. *Two algorithms are available for each major constant. One for computation and one for verification. (great for stress-testing) *Extremely efficient even for large computations (> 1 billion digits). *Swap Space management for large computations that require more memory than there is available. *Multi-Threaded - Multi-threading can be used to fully utilize modern multi-core processors without significantly increasing memory usage. *For large computations, it scales almost linearly with the # of cores. *Multi-Hard Drive - Multiple hard drives can be used for faster disk swapping. (scales linearly - as fast as hardware Raid 0, with no limit to the # of drives) *Semi-Fault Tolerant - Able to detect and correct for minor errors that may be caused by hardware instability or software bugs.

Aside from computing p and other constants, y-cruncher is great for stress testing 64-bit systems with lots of ram.
