Subspace proof of space implementation for GPU (low-level proving utilities)

This crate exposes some low-level primitives to accelerate proof of space implementation on Nvidia (CUDA, Volta+) and AMD (ROCm) GPUs.

The implementation expects 64KB of shared memory and about 1.1GB of VRAM on GPU.

Build requirements

CUDA

For Nvidia support CUDA toolkit needs to be installed, which can be done on Ubuntu 24.04 like this:

sudo apt-get install nvidia-cuda-toolkit

In case you have newer GCC installed, you may need to install g++-12 and set it as a C++ compiler of choice during compilation, something like this:

CXX=g++-12 cargo build

For other operating systems/platforms check official documentation: https://docs.nvidia.com/cuda/

ROCm

For AMD/ROCm support follow their official documentation: https://rocm.docs.amd.com/en/latest/
