研究方向

The issue requests adding a oneCCL backend by extending the torch native distributed model in `ignite/distributed/comp models/native.py`. Investigate the current implementation and the references to Intel's torch ccl and PyTorch with oneCCL backend. The maintainers have not yet provided implementation guidance, so a contributor should start by understanding the architecture of the existing comp models and how to integrate a new backend similar to the NCCL or Gloo backends. Check the linked references for details on oneCCL integration with PyTorch.
