Take a look at the link. Certainly this will put a small dent in the number of used Playstation 3s available on ebay. Anyone do the calculations on putting together well over 2,000 props? There must be some cousins to a supercomputing idea that are good for special applications taking advantage of over 16,000 cogs. There was a shortage of Propeller chips. Gets you thinking...

    I guess the US Air Force uses a lot of propellers, just not the ones from Parallax.

    The Cell chip used in the PS3 has a 3.2 GHz Power PC and eight 128-bit co-processors operating in parallel! IBM has a supercomputer based on Cell and AMD Opteron chips which delivers 1.456 petaFLOPS:

    500 Teraflops is not bad, which is what they quoted in the article.
    The Props come to 3,200,000 MIPs.

    They never say anything about software programming.

    Repeat after me while clicking your ruby slippers together three times.. "it's a microcontroller, it's a microcontroller, it's a microcontroller"

    That IBM machine uses Linux; it won't run on a single Propeller, let alone 1000s of them. Also, the IBM system has very efficient communications between processors, which the Propeller lacks, and high-speed memory interfaces. As Brad points out, the Propeller is just a micro-controller, and there are much better devices available if you want to connect lots of them together.

    Long Live RISC chips !

    And I thought My G4 cluster of 4 1.33Ghz DP macs was fast in 04'
    dady wants that cluster ! Now !

    "it's a microcontroller,..."


    That's the beauty of it, and the advantage!

    Now say, "There's no place like Prop, there's no place like Prop, there's..."
