I have installed OpenFOAM and Openmpi under /opt/HPC-Apps/. I can load openmpi from module file and run "mpirun --version" successfully.

But when sourcing /opt/HPC-Apps/openfoam/OpenFOAM-v1806/etc/bashrc, got the below error "Cannot open configuration file /opt/openmpi/share/openmpi/mpicc-wrapper-data.txt". But I can run motorbike tutorial successfully.

So my question is that:
Why the bashrc load openmpi from "/opt/openmpi" instead of "/opt/HPC-Apps/openmpi"? How can I fix this if I really want to install openmpi under /opt/HPC-Apps?

Thanks a lot!


PS:
1. the console log is as follows:
[op@hpcapp4 hpc]$ module load /opt/HPC-Apps/openmpi/1.10.7
[op@hpcapp4 hpc]$ mpirun --version
mpirun (Open MPI) 1.10.7

Cannot open configuration file /opt/openmpi/share/openmpi/mpicc-wrapper-data.txt

2. mpi configuration inside /opt/HPC-Apps/openfoam/OpenFOAM-v1806/etc/bashrc:
export WM_MPLIB=SYSTEMOPENMPI

The problem is resolved by adding OPAL_PREFIX to environment variables. See https://users.open-mpi.narkive.com/d...apper-data-txt.
