HipScript – Run CUDA in the browser with WebAssembly and WebGPU2025 · hipscript.lights0123.com · ▲309CUDA is NVIDIA's language for GPU programming, allowing you to mix write CPU and GPU code in C++ in one file. By chaining a few projects that compile CUDA to OpenCL, then Vulkan, then WebGPU, you can experiment with this GPGPU language on any hardware.
Integer Map Data Structure2024 · github.com · ▲91This project presents a new data structure for storing ordered integer maps. The proposed data structure is a compressive, cache-friendly, radix tree that has performance comparable to an unordered map (`std::unordered_map`) and is an order of magnitude faster than an ordered map (`std::map`).
A hash array-mapped trie implementation in C2023 · github.com · ▲171Long-simmering side project that is finally ready to see the light. HAMTs are a cool persistent data structure and implementing one has been a lot of fun. Beyond the code, there is likely some value in the extensive and largely complete implementation docs; basic benchmarks are linked in the README, too. Kind of aiming to be "the libavl for HAMTs". That is obviously a high and aspirational bar but a distinct possibility if it stirs up a little interest and/or contribution. Anyways, it's time for this to go out, collect feedback and maybe even some use outside of toy projects. Let me…
