My .bash_profile and .bashrc on the server are exactly the same as that on my PC. However, I can run mpiexec without any problems just using my PC as a single node, i.e. without trying to login to other servers and using multiple nodes. I only get the errors on the server.
In .bash_profile, I see PATH=$PATH:$HOME/bin If I change this, won't it affect other programs as well? Thank you.
