[Wien] Open MPI

[Laurence Marks]

Not an easy question to answer. The trivial answer is one which works, but
that won't help you!

I have seen problems with anything before 1.4.3, so don't use an early one.
I would recommend looking at the latest release of the "one back" stable
version which I think is 1.6.5 as this is probably a patched & somewhat
stable version, and the latest ( http://www.open-mpi.org 1.8 ?).

One thing that may be important is to use a version compiled with the same
compiler as you use for Wien2k. The command ompi_info -c is useful, also
look at ompi_info -h.

N.B., so long as you are familiar with using conventional ./configure
scripts compiling is simple. Really tweaking it for best performance is a
sys_admin job and well beyond me.
