[Beowulf] GP-GPU experience

> GPU's completely annihilate cpu's everywhere.

this is complete nonsense.  GPUs do very nicely on a quite narrow 
set of problems.  for a somewhat larger set of problems, they do OK,
but pretty "meh", really, considering.  for many problems, GPUs 
are irrelevant, whether that's because the problem uses too much 
memory, or already scales well on non-GPU, or doesn't have a GPU-friendly
structure.

well, for your application, which is quite narrow.
