Subject: [OMPI users] uninstall
From: Jacob Balthazor (jcb344_at_[hidden])

        I downloaded compiled, and installed open mpi off the web site but
was having problems. I then installed open mpi and ins libs via yum.
Adter that I was able to compile and run mpi programs locally but ran
into problems when I tried to run them across two computers (see
output below). I was told that this was probably because I have two
different copies of openmpi. I uninstalled openmpi via yum and am now
trying to figure out the best way to uninstall the compiled version of
openmpi to reinstall with a clean slate. Any suggestions?

This looks like you have two different versions of Open MPI installed
on your two machines (it's hard to tell with the name
"localhost.localdomain", though -- can you name your two computers
differently so that you can tell them apart in the output?).

You need to have the same version of Open MPI installed on both
