[Beowulf] gpgpu

[Vincent Diepeveen]

Hi Mikhail,

I'd say they're ok for black box 32 bits calculations that can do  
with a GB or 2 RAM,
other than that they're just luxurious electric heating.

p.s. if you ask me, honestely, 250 watt or so for latest gpu is  
really too much.
IMHO cpu's as well as gpu's should budget themselves more to a few  
tens of watts at most.
Say 50 watt for the high end models.
