How to set the path to the latest Open MPI version?












0















I'm using Ubuntu 14.04 and the installed Open MPI is 1.6.5; I've installed the Latest Open MPI(4.0.0) following these instructions here and set the installed location by-



./configure --prefix=/$HOME/Downloads/openmpi


Then, to set the path I've added these lines to my .bash_aliases file-



om() {
export PATH=$PATH:$HOME/Downloads/openmpi/bin
export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:$HOME/Downloads/openmpi/lib
}


I've run the om command and then ran mpirun --version but it still outputs-



mpirun (Open MPI) 1.6.5

Report bugs to http://www.open-mpi.org/community/help/


How can I keep and use both the Open MPI versions?
Thank you.
