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
