Burn the Witch! Burn the Witch!

Any HPC installation, if you want to show it off to alumni, august
committees from grant awarding bodies etc.  and not get sand kicked in your
face from the big boys in the Top 500 NEEDS an expensive infrastructure of
various MPI libraries. Big, big switches with lots of flashing lights.
Highly paid, pampered systems admins who must be treated like expensive
racehorses, and not exercised too much every day. They need cool beers on
tap and luxurious offices to relax in while they prepare to do that vital
half hours work per day which keeps your Supercomputer flashing away and
making noises.
