However, am still getting following error message whenever am starting the parallel molecular dynamics simulation using GROMACS. So every time am starting the MD job, I need to source the .bashrc file again. Have you set OPAL_PREFIX to /home/sunitap/soft/openmpi? How to set OPAL_PREFIX? During the installation of openmpi, I ran configure with --prefix=/home/sunitap/soft/openmpi Did you mean this? No.  The "OPAL_PREFIX" steps occurs after you configure, build, and install OMPI.  At the time that you run MPI programs, set the "OPAL_PREFIX" environment variable to /home/sunitap/soft/openmpi.  The syntax depends on your shell.  E.g., for csh: setenv OPAL_PREFIX /home/sunitap/soft/openmpi The sequence might be something like this: ./configure --prefix=/home/sunitap/soft/openmpi make make install cd /home/sunitap/soft/openmpi/examples mpicc connectivity_c.c setenv OPAL_PREFIX /home/sunitap/soft/openmpi mpirun -n 2 ./connectivity_c though I didn't check all those commands out.
