simdrng

simdrng is a C++20 header-only library of scalar and SIMD-accelerated random number generators, with nanobind-powered Python bindings that drop straight into numpy and scipy.

Generator families

• Xoshiro256++ (scalar, SIMD dispatch, -march=native)

• SplitMix64

• ChaCha (8 / 12 / 20 rounds) — scalar, SIMD dispatch, native

• Philox (2x32, 4x32, 2x64, 4x64) — scalar, SIMD dispatch, native
