The `main` training function needed to be broken down into smaller functions for readability/testability. WORLD_SIZE, LOCAL_RANK, and RANK have also been extracted and made global constants since they are set by the administrating multiprocessing launcher (torchrun, in our case). HPU configuration options and checks are also added. Signed-off-by: James Kunstle <[email protected]>
