Excellent. I think I just made it work under Intel's C++ and MPI on an AMD
cluster.
I have a few comments/questions:
1. info is the first output argument in all functions. I think it should be
the second one, so that it can be easily ignored if wanted.
In particular, the check in examples
if not(MPI_Initialized)
info = MPI_Init();
end
makes no sense (unless I'm missing something) because it's the info output
from MPI_Initialized that is tested and that is always zero.
2. include "mpi.h" should precede include "oct.h" everywhere, because oct.h
takes some system headers in. Some MPI libs require this (Intel's MPI does).
3. what's your copyright policy? If I improve some of your functions, can I
retain the copyright?
thx and best regards
it seems this will be a viable (less convenient but more powerful)
alternative to parcellfun/pararrayfun for me.
