Hi all, I solved the problem by doing:
``` INSTALL_DIR=/usr/local/openmpi-5.0.3 export PATH=$INSTALL_DIR/bin:$PATH export LD_LIBRARY_PATH=$INSTALL_DIR/lib:$LD_LIBRARY_PATH export OPAL_PREFIX=$INSTALL_DIR ``` That OPAL_PREFIX line was the tricky one. After doing that, these mpirun commands are now working correctly: ``` mpirun --version mpirun uptime ``` Thanks for pointing me in the right direction! @John Hearns, I'm not setting up a Modules environment, but this sounds like a great solution to the problem. I might need to look into that! Thanks.
