Previously ScaledPartial is causing compiler_toolkit to fail, as it has a dependency on simple_fsdp folder.
Could you add the simple_fsdp folder to https://github.com/pytorch/torchtitan/blob/main/.github/workflows/integration_test_8gpu_compiler_toolkit.yaml#L9
so that whenever simplefsdp folder gets changed, the CI triggers compiler_toolkit CI test? Thanks! cc @sanketpurandare

the error seems on not related
merging because this blocks SimpleFSDP correctness and compiler_toolkit CI
