The Register claims that IBM proposes a new concept for Los Alamos’ new upcoming supercomputer, code-named “Roadrunner”. Both companies are bidding on the project for months, so this solution would be, well, at least very interesting. El Reg writes:
The lab will announce that IBM will build Roadrunner using a hybrid design that makes use of Opteron and Cell systems, according to a report from online rag CNET. The publication cites “sources familiar with the machine” as claiming that the National Nuclear Security Administration (NNSA), which oversees LANL, will reveal IBM’s win “in the coming days.”
So The Reg is quoting CNET, but not giving any pointers, couldn’t find the source yet, so… I file this under “rumours” :)
There was no word yet about how the Cell– and Opteron-CPUs should be integrated; I bet a fiver that they’re going to use HyperTransport and install a Cell-CPU as a Co-processor to the Opterons – probably similar to the technology DRC Computer is using for their Virtex-FPGA integration-solution.
If not, what else would be possible? PCI-Express, for sure, but probably too expensive on a large scale. Ideas, do you know more than Big Reg? Tell me! Or use the fancy comment-function.
