I have always wanted to learn about GPU programming. Now might be the time.

  I couldn't resist, so here's the GPU hasher: https://gist.github.com/grishka/c1be1c035f39564debfd4b195bdfcac4 https://gist.github.com/grishka/c1be1c035f39564debfd4b195bdf... It gets around 232.5 MH/s on the M1 Max. There's also an optimization that exploits the fact that SHA256 is incremental, so the state for the common prefix could be pre-computed and then copied and only updated with the variable part. This yields around 30% performance boost.

    I'm able to get 250MH/s with this. M1 Pro

      I made some improvements and it's now 340MH/s
