[Wien] MPI

[Laurence Marks]

One that works.

Some versions of openmpi have problems although that is probably the
best option for the future. There are some tricky issues with openmpi
related to how your flavor of ssh works, there is no standard and some
do not propogate kill commands which means that they can leave
orphans.

An alternative is mvapich. In a benchmark that I did a few months ago
the Intel mpi was much better for AVX instructions, but that may have
changed.

Openmpi is easy to compile; mvapich can be a little trickier.

N.B., if you have fast connections, e.g. infiniband, they are more
than fast enough and I have never seen this as rate limiting with
Wien2k. With ethernet it matters.
