You're right about application of a PPU in a Beowulf. I just happen to
run galaxy dynamics on my Beowulf. Most of that is Newtonian
gravitational calcs so a "raw" PPU could be a nice thing to have.

Strictly speaking this leads us away from the Beowulf model of COTS but
I threw it in as an example of the potential gains from gaming in some
science applications.
