openMPI 1.0.1 is installed on the ParallelKnoppix CD
(http://pareto.uab.es/mcreel/ParallelKnoppix) in /usr/local, and seems
to work fine. There's a montecarlo pi calculator in the Examples/C
directory that is set up to compile and run using openMPI. More
interesting examples that anyone would like to contribute are welcome.
