# Motivation This PR intends to add UTs for accelerator device-agnostic APIs. # Additional Context This PR is relanded. It is reverted because `torch.Event` doesn't support mps backend. We have fixed it in #142468. The previous commit is 952514f Pull Request resolved: #133572 Approved by: https://github.com/EikanWang, https://github.com/albanD ghstack dependencies: #143171

Motivation
Support
torch.accelerator.synchronize()on mps. The root cause is that MPS doesn't support lazy initialization. So we must check if the current accelerator supports device lazy initialization rather than early return.Additional Context
Add a mps UT to test code change.
