+ - Microsoft Supercharges Bing Search With Field Programmable Arrays->

Submitted by mpicpp
mpicpp writes: Using FPGAs, Microsoft engineers are building a kind of super-search machine network they call Catapult. It’s comprised of 1,632 servers, each one with an Intel Xeon processor and a daughter card that contains the Altera FPGA chip, linked to the Catapault network. The system takes search queries coming from Bing and offloads a lot of the work to the FPGAs, which are custom-programmed for the heavy computational work needed to figure out which webpages results should be displayed in which order.

The FPGAs are 40 times faster than a CPU at processing Bing’s custom algorithms, Berger says. That doesn’t mean Bing will be 40 times faster–some of the work is still done by those Xeon CPUs–but Microsoft believes the overall system will be twice as fast as Bing’s existing system. Ultimately, this means Microsoft can operate a much greener data center. “Right off the bat we can chop the number of servers that we use in half,” Burger says.
