Various Corrdiff optimizations for drastic increase of training efficiency

Description

  • Updated CorrDiff training code to support multiple patch iterations
    to amortize regression cost and usage of torch.compile
  • Refactored modulus/models/diffusion/layers.py to optimize data type casting workflow,
    avoiding unnecessary casting under autocast mode
  • Refactored Conv2d to enable fusion of conv2d with bias addition
  • Refactored GroupNorm, UNetBlock, SongUNet, SongUNetPosEmbd to support usage of
    Apex GroupNorm, fusion of activation with GroupNorm, and AMP workflow.
  • Updated SongUNetPosEmbd to avoid unnecessary HtoD Memcpy of pos_embd
  • Updated from_checkpoint to accommodate usage of Apex GroupNorm
  • Refactored CorrDiff NVTX annotation workflow to be configurable

What's the status of this? I would love to make use of these in ReGen.

@simonbyrne it's currently blocked by #790 and under review, but that will be merged in the coming days.
AFAIK the current implementation of ReGen does not support these optimizations and there will be some work required to do so.

Hey @jialusui1102, @CharlelieLrt and talked about the backward compatibility issues this PR and this PR #790 raised. For now we can get this in but I will fix the backward compatibility stuff ASAP after. @CharlelieLrt and I discussed a solution that seems to solve all the issues. Ill need you @jialusui1102 to take a look at the PR when the time comes though to make sure this works with the corrdiff model.

Hey @loliverhennigh Thanks for letting me know and merging my PR in and thanks @CharlelieLrt for coordinating. Let me know when the PR is ready and I will test the corrdiff checkpoint to make sure everything works!
