SuperMicro demos 4 and 7 GPU boards
 

SUPERMICRO WAS AT IDF showing off the usual server and workstation toys. Because it had a bunch of new products at Computex, and there haven't subsequently been any really new Intel chips, the boards on display were evolutionary, not revolutionary.

The first one is the X8DTH-6F we told you about at Computex. It is a real product, and you can buy it now. That plus 7 Junipers and a few low power Nehalems would make a dandy high efficiency HPC compute node. Go buy 17 now, you won't regret it until the credit card bill comes in.
