[Wien] MPI Strategy

[Laurence Marks]

I've seen this sort of trend elsewhere, sysadmins expecting users to only
run one mpi job rather than parallel ones, and this can lead to problems for
Wien2k. Some possibilities:

1. Run everything as 1 mpi. This is less efficient, quicker for you.
2. Use rsh, or ask a sysadmin for an equivalent.
3. Set mpi_remote and/use_remote to 0. The different mpi will then be
launched from one node but should execute according to your machines
breakdown.
4. If desperate, and comfortable with shell programming, edit parallel
options so it in fact runs a csh or sh on remote nodes. This is needed for
some openmpi because it does not export some environmental variables.
