mpirun notes


We often use mpi to run multi-node parallel computing programs. Currently, we use openmpi-2.0.2 to set up our system.


We ususally install openmpi into the directory like /usr/local/openmpi-x.x.x, where x.x.x is the version id.


  1. Do remember to add install-dir/lib to LD_LIBRARY_PATH, install-dir/bin to PATH.
  2. Do remember to add certain paths to .bashrc and source it.
  3. Adding certain paths to .bash_profile if you want.
