Subject: [OMPI users] -prefix option to mpirun.
From: Ashley Pittman (apittman_at_[hidden])

Hello,

I work for medium sized UK based ISV and am packaging open-mpi so that
is can be made available as an option to our users, so far I've been
very impressed by how smoothly things have gone but I've got one problem
which doesn't seem to be covered by the FAQ.

We install openmpi to /opt/openmpi-1.2.5 and are using the modules
command to select which mpi to use, the modules command correctly sets
PATH to pick up mpicc and mpirun on the head node however the issue
comes with running a job, users need to specify -prefix on the mpirun
command line. Is there a way to specify this in the environment so I
could make it happen automatically as part of the modules environment?

I've searched the archives for this, the closest I can find is this
exchange in 2006, if I specify a full path to mpirun then it does the
right thing but is there a way to extend this functionality to the case
where mpirun is run from path?
