  3. GPUPrefixSums

    A nearly complete collection of prefix sum algorithms implemented in CUDA, D3D12, Unity and WGPU. Theoretically portable to all wave/warp/subgroup sizes.

    Lol do you think "PTX programming" is some kind of secret source of perf? It's just inline asm. Sometimes it's necessary but most of the time "CUDA is all you need":

  4. webglc

    WebGL Compute

    Mm, I used that very writeup as a reference to implement this algorithm in WebGL 3 years ago: https://github.com/ashtonsix/webglc/blob/main/src/kernel/sca...
