Hello,
I’m fiddling with the profiling layer, and I want to convert a
communicator-specific rank to global rank. Is there a good way of
doing this?
I was thinking maybe MPIL_Comm_gps() would get me halfway there, but
I’m not seeing a way to go from the gps data to a rank in
MPI_COMM_WORLD (I’m assuming there’s only one MPI_COMM_WORLD).
Thoughts?
