Ananth Veluvali(@AnanthVeluvali):I connected devin to some @modal H100s and then left it alone to run its own experiment loop against the GPUs. it found a way to reduce peak memory by up to 46% and latency by up to 52% on a popular OS training-kernel repo. since the triton kernel was already near peak HBM bandwidth, it focused on other things, removing a 2GB allocation that was happening on every chunk of the backward pass. then it ran the benchmarks to confirm the speedup 🤯
