IEEE Says Multicore is Bad News For Supercomputers

Posted by timothy on Friday December 5, 2008 @12:04AM 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.'"

This is slashdot, our professions are computer related not literature based. You're on the wrong website.
If your code was as crappy as your spoken language, would it compile? Precision and correctness counts.
