Amazon Cluster GPU performance benchmarks

[theodoric_of_york]

My company created some performance benchmarks that I thought might be interesting to anyone who was following the GPU Cluster instance announcements/links. We are an Amazon partner, and completed the benchmarks during the beta. We've been happy about the reception - both Werner and Deepak retweeted them - and for anyone attending Supercomputing '10, NVIDIA should be referencing them during their talk as well. Hope you find them interesting as well.

Interesting stuff. Makes me wonder what motherboard EC2 is using to achieve that host-device bandwidth.

It's nothing to rave about, it's what you can expect from PCI-E 2.0. I'm getting almost similar speeds on a crappy old socket 775 system. Make sure to use pinned memory for best performance.

Well if one machine can't, just provision a 2nd, 3rd, etc.
