biski64

biski64 is an extremely fast PRNG I wrote for non-cryptographic tasks. GitHub (MIT): https://github.com/danielcota/biski64 Highlights: * ~0.40 ns/call. 100%+ faster than xoroshiro128++. * Easily passes BigCrush and PractRand (64TB). * Invertible and proven injective via Z3 Prover. * Scaled down versions show even better mixing efficiency than well respected PRNGs like JSF. * Minimum 2^64 period and parallel streams - through the use of a 64-bit Weyl sequence. * no_std compatible in Rust (implements RngCore) and requires only stdint.h in C. Seeking feedback on design, use cases, and further testing.

biski64 is a fast C PRNG I wrote for non-cryptographic tasks. GitHub (MIT): https://github.com/danielcota/biski64 Highlights: * ~0.42 ns/value (GCC 11.4, -O3 -march=native), 92% faster than xoroshiro128++. * Easily passes PractRand (32TB), exceptional BigCrush results (running BigCrush 100 times against established PRNGs). * Guaranteed 2^64 period - through the use of a 64-bit Weyl sequence. * Parallel streams, robust reduced state size tests. * Core requires only stdint.h. Details on the 100x BigCrush tests (including reference PRNG results), parallel streams and reduced state size tests can be found in the Github README). Seeking feedback on design, use cases, or further testing.
