[Beowulf] Stress / torture test cluster hardware

While I would not call it torture (biting lip to not make
sarcastic remark), the BPS (Beowulf Performance Suite)
was developed to:

1) make sure things were working at various levels
2) generate baseline performance data to help measure
   see what happens when things change (i.e. compilers,
   kernels, MPI's)

You can read about it here (and download the tar ball):

One of the main components is the NASA parallel suite
that is based on real computational patters and is self
checking -- which is important when things get near the edge.
I have been improving my main driver script that allows
various compilers, MPI's, problem sizes, and numbers of nodes
to be tested.

Another real world tests is to try running Gromacs
which is known to stress the systems quite a bit.
>From the gromacs wb page:

"Gromacs is running the x86 CPUs hotter than any other program
we know of, including dedicated testing programs like cpu-burnin."

There is more here:

Happy stressing.
