Reverse Multithreading CPUs

microbee writes "The register is reporting that AMD is researching a new CPU technology called 'reverse multithreading', which essentially does the opposite of hyperthreading in that it presents multiple cores to the OS as a single-core processor." From the article: "The technology is aimed at the next architecture after K8, according to a purported company mole cited by French-language site x86 Secret. It's well known that two CPUs - whether two separate processors or two cores on the same die - don't generate, clock for clock, double the performance of a single CPU. However, by making the CPU once again appear as a single logical processor, AMD is claimed to believe it may be able to double the single-chip performance with a two-core chip or provide quadruple the performance with a quad-core processor."

    Too late. I've already patented it.

    To heck with powering millions of individual computers. Just make a million-core chip and wire them all up like this and you'll have one computer with the power of millions less all that nasty overhead of having to run an OS on all of the other computers. Power to the people!
