Description
This PR adds the selective averaging implementation originally written by Vasim @yuk12, with minor cleanup and refactoring.
To use the selective averaging implementation based on torch.distributed written by @younik, set
--spawn-backend dist(choices: ["dist", "mpi"]).Two MPI4PY-based selective averaging implementations are available. To select between them, use
--mpi-sa-mode(choices: ["general", "fast"]).Please let me know if there are any additional refactoring opportunities or improvements to consider.
