Tags: gpu, cuda, performance-tool, web-tool

Score: 4.0/10 (Innovation: 3, Technical: 4, Documentation: 7, Utility: 5)

A web-based tool that replicates NVIDIA's CUDA occupancy spreadsheet, allowing GPU developers to estimate theoretical occupancy based on block size, registers per thread, and shared memory per block. It's interesting because it provides an accessible, browser-based alternative to a specialized spreadsheet, with clear explanations of occupancy limitations and practical considerations for modern GPUs.

Target audience: backend devs, data engineers, ai-ml engineers
