There was a problem hiding this comment.
Two overall points:
- we would have to make capturable public and thus we should do our due diligence in adding tests, documentation and any checks to ascertain legitimacy. If you want code pointers, see my NAdam PR #106615
- it would be good to not have our implementation be extremely split up into a huge if else block. I've written up some suggestions that should just make the OG implementation capturable. I did just use GitHub comment as my IDE so the disclaimer is that you should definitely verify with tests/linting 😛

tfsingh I got to it first--wanted to land this stack and close the gap ASAP. This PR also fixes a discrepancy between `_init_group` and `__set_state__` because we have the constants live on params' device always. There are some next steps though: - ASGD can be made faster by making etas, mus, steps be on CPU when NOT capturable. (I had mistakenly thought foreachifying was faster and so we landed #107857, but it is slower). No one has complained yet though. ¯\_(ツ)_/¯ cc voznesenskym penguinwu EikanWang jgong5 Guobing-Chen XiaobingSuper zhuhaozhe blzheng wenzhe-nrv jiayisunx peterbell10 ipiszy yf225 chenyang78 kadeng muchulee8 aakhundov ColinPeppler amjames desertfire chauhang [ghstack-poisoned]
