Comment (by hinder):
Will mpirun choke on a request for more? That must be system-dependent. If I run on my laptop, I can ask mpirun for as many processes as I like. I think Erik calls this "oversubscribing". I don't think that running a test case on 2 processes rather than 1 is going to "bring a machine down". The performance will of course be lower, but these are not benchmarks.
