There’s now a bit more information available about Roadrunner, the new supercomputer for the Los Alamos National Laboratories. We remember, AMD and IBM were fighting for months to get the contract, with a surprising result in the end: Opterons and Cell Broadband Engine (based on IBM’s Power CPU) will be used to build a hybrid supercomputer.
IBM released a bit more information (that was already five days ago, it somehow sneaked under my radar). First of all, IBM won the bid. Second, Roadrunner is supposed to have a peak-performance of 1.6 Peta-FLOPS:
The machine is to be built entirely from commercially available hardware and based on the Linux® operating system. IBM® System x™ 3755 servers based on AMD Opteron technology will be deployed in conjunction with IBM BladeCenter® H systems with Cell B.E. technology. Each system used is designed specifically for high performance implementations.
Designed also with space and power consumption issues in mind, the system will employ advanced cooling and power management technologies and will occupy only 12,000 square feet of floor space, or approximately the size of three basketball courts.
That was basically everything, no word on how the Opterons should be connected, so we’re all still waiting for more on this topic. I still bet a fiver that they’ll use HyperTransport; AMD and IBM are both members of the HyperTransport Consortium.
