    Hi

    I am wondering:

    The Intel processor I'm using is able to calculate the SuperPI number crunching

    benchmark to one million digits in about 100 seconds. It takes my Pentium 4 system

    less than two minutes to figure out this benchmark, and the Pentium 4 is notoriously

    bad at FPU calculations.
    Does his machine calculate pi to one million digits faster when booted with
    a linux system than when booted with a windows system, given the "same amount
    of background load like services etc." ?

    This is the question people using super computers really are worried about.
    Super computer nodes often do not even have a dvd drive ... the two main
    reasons, in my opinion as a (former) user and evaluator of super computers,
    why linux is often used, are

    a) administrators/builders, in particular in the scientific environment, are used to

    linux (maintenance, writing drivers, ...)

    b) the field of batch-queueing systems is much more mature in the linux world
    ( because of a)? )

    Cheers

    The funny thing is, what the author is ranting about isn't necessarily an OS bug. See The dangers of sleeping on a UI thread -- 'Your non-responsive hidden window has just created a "Windows seems to hang for a few seconds at random intervals" bug.'
