`sloth256-189`

Encoder/decoder for the Subspace Network Blockchain based on the SLOTH permutation

This is an adaptation of SLOTH (slow-timed hash function) into a time-asymmetric permutation using a standard CBC block cipher.

This library consists of 3 major implementations: - CPU - CUDA (requires cuda feature to be enabled) - OpenCL (requires opencl feature to be enabled)

CPU

CPU Implementation contains 3 flavors: * optimized assembly-assisted implementation for x86-64 processors with ADX ISA extension (Linux, macOS and Windows) * any 64-bt platform with support for __int128 C type (modern GCC/Clang, but not MSVC) * fallback for other platforms

For more details, README.md under src/cpu can be referred.

CUDA

CUDA implementation is heavily using low-level PTX code to achieve the maximum performance.

Details of the CUDA implementation can be found in README.md under src/cuda.

OpenCL

OpenCL is a universal implementation that supports AMD (ROCm), Nvidia (CUDA) and Intel GPUs, including support for multiple GPU vendors on the same machine at the same time.

Details of the OpenCL implementation can be found in mod.rs under src/opencl.
