Subject: [Beowulf] gpu benchmark

I'm looking for a benchmark that can keep a gpu busy (ideally both compute and memory) for 2 or 3 hours.  but here's the kick, at the end of the benchmark it needs to check it's answers

i'm trying to hunt down some potentially bad hardware.  linpack works great for the bulk of it, but the nodes i have, have more gpu power then ram available, so a linpack run using the full ram of a single box doesn't run long enough.  and successive runs one after another doesn't seem to trigger it

i can trigger the error using large mpi jobs across many nodes, but that doesn't let me isolate which gpu was at fault.  and since these are GTX level cards, no ecc and no error diagnostics on the console...

i'm going through my bag of tricks, but haven't come up with anything just yet.
