[maker-devel] Maker MPI with MPICH

[Carson Holt]

You have a mixed MPI setup.  You said you are trying to run under MPICH, but your error message says you are mixing with OpenMPi for example —> ompi_mpi_init: orte_init failed

That is an OpenMPI error message.

MPI flavors are incompatible with each other.  To run one you have to completely unload the other (i.e. remove it from your PATH, LD_PRELOAD, LD_LIBRARY_PATH, etc.).  Once the othe MPI flavor is unloaded you have to recompile the program you want to run using the new MPI flavor, otherwise all code bindings will still point to the other MPI flavor’s libraries because of how dynamic linking works.  This means you have to have a separate independent install of each program you want to switch to a new MPI flavor, and you must unload the old installations from your PATH before launching.

Thanks,
Carson
