Deprecate shmem_sync_all? #451

Open akhillanger opened 3 years ago

akhillanger commented 3 years ago

Since shmem_sync_all routine is equivalent to calling shmem_team_sync on the world team, is there a reason to keep shmem_sync_all API?

nspark commented 3 years ago

Generally, I've favored keeping shmem_sync_all and shmem_barrier_all because I think that first-time users shouldn't have to understand all the layers of the API to write their first OpenSHMEM program. As users become more familiar with OpenSHMEM, they can peel back the layers of the onion and give themselves more control. If we never had them to begin with, I wouldn't necessarily add them simply for convenience, but I still think they're worth keeping.

For comparison, it was a long time after I first started writing MPI programs that I ever needed a communicator other than MPI_COMM_WORLD.

@akhillanger Can we close this issue, or would you still like to pursue deprecation?
