I have successfully installed openmpi locally in a compute cluster (CentOS system) without sudo privileges. So the location of installed openmpi is non-standard. Lets say the location of the installed file is $/home/username/openmpi. The bin, lib, share, include folders are in openmpi folder. For system to recognize mpirun, I have added the location of bin folder (/home/username/openmpi/bin) in $PATH, and lib folder to $LD_LIBRARY_PATH. However, the share folder is not recognized by mpirun binary and therefore it fails. So, to which environment variable should I add the share folder? Thank you in advance for your insights and help.
I get the following error when I run mpirun.
`$mpirun
Sorry! You were supposed to get help about: opal_init:startup:internal-failure But I couldn't open the help file: /usr/local/share/openmpi/help-opal-runtime.txt: No such file or directory. Sorry!
The file help-opal-runtime.txt is located in /home/username/openmpi/share/openmpi/
Among the posts I have seen, they only recommend adding locations in $PATH and $LD_LIBRARY_PATH, so I need some help figuring out how to correctly add paths in the environment variables so that the share folder is searchable.
I have also attempted adding /home/username/openmpi and /home/username/openmpi/share/openmpi to $PATH but it does not solve the issue.
I have similar issues with mpicc, mpic++, etc.
