Thanks so much for the suggestions! code updated. And for further replication, I will submit a follow-up PR today. And for the rest, I would be very happy if you could help.

Do you really need "BACKEND_RESET_MAX_MEMORY_ALLOCATED"? This function will all reset_peak_memory_stats anyway as can be seen from here: https://pytorch.org/docs/stable/generated/torch.cuda.reset_max_memory_allocated.html

We can look at this in another PR.

yes, I run the tests on xpu and except backend_reset_max_memory_allocated, all tests work. But I can fix it in another PR as @hlky mentioned earlier.

@faaanybackend_reset_max_memory_allocated should be a no-op for non-cuda, if it's giving an error we'll need to fix that. I was referring to using reset_max_memory_allocated when that function has changed to also call reset_peak_memory_stats, we'll review that change in behavior later.

[faaany]

sure, let me update.

Hi @sayakpaul@hlky@DN6 , could you do final-round review? Since I will have follow-up PRs, it would be great that it could be merged this week. Thanks a lot!

Hi folks, any feedback?
