I'm having problems running programs compiled against the OpenMPI 5.0.1 package provided by homebrew on MacOS (arm) 12.6.1.
When running a Fortran test program that simply calls MPI_init followed by MPI_Finalize, I get the following output: $ mpirun -n 2 ./mpi_init_test -------------------------------------------------------------------------- It looks like MPI_INIT failed for some reason; your parallel process is likely to abort. There are many reasons that a parallel process can fail during MPI_INIT; some of which are due to configuration or environment problems. This failure appears to be an internal failure; here's some additional information (which may only be relevant to an Open MPI developer): PML add procs failed --> Returned "Not found" (-13) instead of "Success" (0) -------------------------------------------------------------------------- -------------------------------------------------------------------------- It looks like MPI_INIT failed for some reason; your parallel process is likely to abort.

The first process to do so was: Process name: [prterun-haiducek-lt-15584@1,1] Exit code: 14 -------------------------------------------------------------------------- I'm not sure whether this is the result of a bug in OpenMPI, in the homebrew package, or a misconfiguration of my system. Any suggestions for troubleshooting this?
