Hello, I'm experiencing issues running simple `mpirun` commands, after installing OpenMPI v5.0.3.
When I run any command with `mpirun`, for example: ``` mpirun --help mpirun --version mpirun uptime mpirun hello_c.c ``` I end up with the following error (in every case): ``` -------------------------------------------------------------------------- Sorry! You were supposed to get help about: prterun-exec-failed from the file: /usr/share/openmpi/help-mpirun.txt: No such file or directory But I couldn't find that topic in the file. Sorry! -------------------------------------------------------------------------- ``` I've installed OpenMPI using these steps: https://docs.open-mpi.org/en/v5.0.x/installing-open-mpi/quickstart.html When I install an older version of OpenMPI (such as v4.0.5), I end up with the following error instead, when running `mpirun`: ``` -------------------------------------------------------------------------- It looks like opal_init failed for some reason; your parallel process is likely to abort. There are many reasons that a parallel process can fail during opal_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): opal_shmem_base_select failed --> Returned value -1 instead of OPAL_SUCCESS -------------------------------------------------------------------------- ``` You can find all the log files over here: https://drive.google.com/drive/folders/163N5Xx5UJZ7fKU172VZSGF2nPY6z0tJF?usp=sharing Love to get some help on this. Thanks. Best, Terence
