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

PATHis searched in order: if you want the new version to be found first, you will need to prepend rather than append the location i.e.export PATH=$HOME/Downloads/openmpi/bin:$PATH

Yes, that worked. You should put it as an answer.
