Description

This PR extends the operation-based API (see #707) with LayerNorm, RMSNorm, and FP8 cast operations.

Compare with the existing module-based API:

# Module-based API
module1 = te.LayerNormLinear(...)

# Operation-based API
module2 = te.ops.Sequential(
    te.ops.LayerNorm(...),
    te.ops.Linear(...),
)

Type of change

  • Documentation change (change only to the documentation, either a fix or a new content)
  • Bug fix (non-breaking change which fixes an issue)
  • New feature (non-breaking change which adds functionality)
  • Breaking change (fix or feature that would cause existing functionality to not work as expected)
  • Infra/Build change
  • Code refractor

Changes

Please list the changes introduced in this PR:

  • LayerNorm operation
  • FP8 cast operation
  • RMSNorm operation

Checklist:

  • I have read and followed the contributing guidelines
  • The functionality is complete
  • I have commented my code, particularly in hard-to-understand areas
  • I have made corresponding changes to the documentation
  • My changes generate no new warnings
  • I have added tests that prove my fix is effective or that my feature works
  • New and existing unit tests pass locally with my changes

I believe you said that it is mostly an utility op for tests, right? We should probably mention that in this documentaiton.

Also maybe we should consider generalizing it a bit with a name that is not specific to FP8? (Like just Quantize)?

It could be a helpful op for users as well. For example, if a user wants to have discrete layers for design reasons but still wants to fuse some operations with FP8 casts:

act = te.ops.Sequential(te.ops.GeLU(), te.ops.Quantize())
linear = te.ops.Sequential(te.ops.Linear())
y = act(x)
z = linear(y)
