Subject: Re: [OMPI users] UC Installation of openmpi-1.4.4
From: Rushton Martin (JMRUSHTON_at_[hidden])

SuSE supports an application mpi-selector which installs when you load
the (broken) SuSE version of OpenMPI. According to your choice of mpi
implementation it will correctly set PATH, MANPATH and LD_LIBRARY_PATH
for you.

The initial installation drops the usual pair (.sh, .csh) of scripts
into /etc/login.d. When one of them runs it locates the appropriate
default (set at system or user level) and includes an appropriate script
from /var/mpi-selector/data. If you manually create an instance of
openmpi you will have to create the relevant scripts. We currently
have:

openmpi-1.3.csh openmpi-1.3.sh openmpi-1.4.1.csh openmpi-1.4.1.sh

The selector program will gives the coice of "openmpi-1.3" or
"openmpi-1.4.1" and sets the default for the NEXT login.

It's a little simplistic, but it seems to work fine.

Is the path to your opempi libraries in your LD_LIBRARY_PATH?
