[Beowulf] cuda benchmark

[Michael Di Domenico]

There has been a lot of talk here lately about cuda, i'm just curious what
people here use to benchmark (if at all) GPU's.  I have access to twelve
nodes of a larger cluster that have high end nvidia cards and infiniband.
 It's used for visual processing of CFD.
Does anyone have a simple micro benchmark that can be spread across the
nodes and crunch some numbers using cuda?  I haven't been able find anything
like that or i'm just looking in the wrong place.
