Project mention: Tracing torch.cuda.empty_cache() on an RTX 4090 - Where Do the 53 MB Go? | dev.to | 2026-05-28
pytorch/pytorch#173382 - a user calls torch.cuda.empty_cache() after deleting tensors, but GPU memory stays allocated. The caching allocator's empty_cache() only releases blocks it has marked as free, but the user sees a persistent gap between "allocated" and "reserved" memory. We traced what happens when torch cuda empty cache runs on an RTX 4090 and measured exactly how much GPU memory it reclaims.
