Show HN: A web-based replacement for Nvidia's CUDA occupancy spreadsheet

A web-based replacement for Nvidia's CUDA occupancy spreadsheet is a company in show hn launch.

Profile

NVIDIA still ships their occupancy calculator as an Excel file from the SM 7.x era. I wanted something I could link a colleague to, that supports newer architectures (Hopper, Ada, Blackwell) and shows the sweep across block sizes inline.It's pure client-side JS — no backend, no tracking, no signup. The math lives in formulas.js so you can sanity-check it against the CUDA Programming Guide. Architectures and their per-SM limits are in presets.js.Things I'd love feedback on:* Are the per-arch limits correct for [arch you're least sure about]?* The "compare two configs side-by-side" view - is the diff readable?* Anything you wish the Excel version did that this doesn't?Link: https://toolbelt.wi

A web-based replacement for Nvidia's CUDA occupancy spreadsheet is positioned in show hn launch, a segment that rewards a clear, focused offering.

It is recorded at the Show HN launch stage.
