Just as a side-note, I've got a couple Tesla's that aren't doing
terribly much at the moment and they're in a Linux 'server'-type box
from Penguin computing. I could certainly install PG on it and run some
tests- if someone's written the code and provides the tests.

I agree that it'd be interesting to do, but I share Lord Stark's
feelings about the challenges and lack of potential gain- it's a very
small set of queries that would benefit from this. You need to be
working with enough data to make the cost of tranferring it all over to
the GPU worthwhile, just for starters..

Thanks,

Stephen
