IEEE Says Multicore is Bad News For Supercomputers

Posted by timothy on from the unexpected-downsides dept.

Richard Kelleher writes "It seems the current design of multi-core processors is not good for the design of supercomputers. According to IEEE: 'Engineers at Sandia National Laboratories, in New Mexico, have simulated future high-performance computers containing the 8-core, 16-core, and 32-core microprocessors that chip makers say are the future of the industry. The results are distressing. Because of limited memory bandwidth and memory-management schemes that are poorly suited to supercomputers, the performance of these machines would level off or even decline with more cores.'"

    Once we get to 32 or 64 core cpus that cost less than $100 (say, five years), I'd HATE to have a beowulf cluster of those!

    Hey dipshit. When you mock someone's grammar, you'd sure as fuck better not mis-spell 'apostrophe'

    Idiot.

    I'll paste it a few times so you can look at your grotesque failure more:

    aprostrophe
    aprostrophe
    aprostrophe
    aprostrophe

    See how stupid that looks?
