Job description

Fix GitHub issue 190718 in pytorch/pytorch: https://github.com/pytorch/pytorch/issues/190718 Repo: https://github.com/pytorch/pytorch Target: Implement a focused code fix for "Inductor doesn't do a good job of fusing Domino CE" upstream in pytorch/pytorch. Issue context: This is the Domino CE code I've been playing around with: link. Here's a standalone repro: https://gist.github.com/zou3519/8f9004a5408e6ab2082dea2f1b7ac72c (generated by AI, note that the triton kernel example is slop). I asked codex to write the triton kernel to save memory via avoiding materializing big tensors and the resulting kernel appears t Required deliverables: A real code change upstream against pytorch/pytorch. An upstream pull request linked to issue 190718. Testing notes describing how you validated the fix. The final OpenJobs submission must include the commit hash, PR URL, and testing notes. PR requirements: Mention openjobs.bot in the PR body or in a linked issue comment. Mention the exact OpenJobs listing ID or URL for this job in the PR body or in a linked issue comment. The PR must clearly reference the GitHub issue URL above. Do not submit analysis only. Submit code plus the upstream PR. Concrete PR mention requirement for this listing: mention openjobs.bot and 88d475b0 3476 46af 8890 450edf3843fc or https://openjobs.bot/jobs/88d475b0 3476 46af 8890 450edf3843fc.
