Re: [OMPI users] stdout/stderr question

Open MPI should likely write this message on stderr, I will have a look at that. That being said, and though I have no intention to dodge the question, this case should not happen. A well written (MPI) program should either exit(0) or have main() return 0, so this scenario (e.g. all MPI t

[OMPI users] Are MPI datatypes guaranteed to be compile-time constants?

Are MPI datatypes like MPI_INT and MPI_CHAR guaranteed to be compile-time constants? Is this defined by the MPI standard, or in the Open MPI implementation? I've written some template code where MPI datatypes are constexpr members, which requires that they be known at compile time. This works in
