Multi-Threaded Programming Without the Pain

Posted by kdawson on from the chicken-run dept.

holden karau writes "Gigahertz are out and cores are in. Programmers must begin to develop applications that take full advantage of the increasing number of cores present in modern computers. However, multi-threaded development has been notoriously hard to do. Researcher Stefanus Du Toit discusses and demonstrates RapidMind, a software system he co-authored, that takes the pain out of multi-threaded programming in C++. For his demo he created a program on the PlayStation 3 representing thousands of chickens, each independently tracked by a single processing core. The talk itself is interesting but the demo is golden."

      Since the egg thread is always converted to a chicken thread while the chicken thread spawns new subthreads, the egg came first. QED.

      They're multi-threaded... They can come at the same time.

    that means in 7.5 years we'll have 128 cores.
    What a pity 640 isn't a round power of 2. That ought to be enough for anybody.

    Well, given that the chicken demo did scale, aren't you curious as to what they are doing differently? Not using Java? :-)
