ClawHammer vs y-cruncher

Both stand on pc stress testing tools. Which one you can start free with, which one lets you read the code, and what each costs once you pay.

y-cruncher combines large calculations with benchmarking and stress testing, and supports Windows and Linux. Consider the Linux build tradeoffs, the project’s hiatus on major redesigns, and licensing terms for commercial use.

ClawHammer: what it does well

y-cruncher: what it does well

Calculates constants to trillions of digits
Separate computation and verification algorithms for most constants
Supports SSE, AVX, and AVX512
Manages swap space for large computations
