Comment (by knarf):
Some mpi implementations will choke on asking for more processes than known from the hostlist which they get from the batch system. You are right about 2 processes on a 1-processor system, but it is easy to come up with more problematic scenarios.
What I think it more important it to fix why we need to have these specific processor numbers in the first place. Most of the time it is probably the ASCII output. Assuming we get finally someone working on hdf5 testsuites this could be history.
