Alternatives to y-cruncher
y-cruncher is aimed at very large calculations: it computes Pi and other mathematical constants to trillions of digits, with separate computation and verification algorithms for most constants. It also works as a multithreaded benchmark and stress test, using SIMD instruction sets such as SSE, AVX, and AVX512. For large jobs, it can manage swap space across drives and correct minor errors linked to instability or software bugs. Non-commercial and academic use is free;…
