    Hey guys... How about a double processor version of pegasos? Would it need just a different cpu module (with two cpu attached to it) or the PCB design of the whole motherboard should be changed? Should MorphOS be radically changed to suuport the new hardware?
    Imagine having 2 of the new G4's @ 1.4GHz each, inside your peggy and doing stuff like video encoding, image processing and 3d rendering in applications that support multiprocessing and AltiVitec! ;-)

    There is pretty much no sane way to introduce Multi-CPU-support
    into any "Amiga"-OS, without breaking more than you fix, or coming
    up with an half-asses solution.

    The Q/Box is still faaaaaaaar away from the point where it would make
    sense to code apps for it.

    Dual-CPU only makes sense when you have apps designed for it, as the
    majority won't run more than one heavy task at a time.

    Dual-CPU only makes sense when you use the top-of-the-range CPU,
    since buying/building a system with 1 fast CPU is cheaper than doing
    it with 2 medicore one. In our case this would be the IBM970 (aka G5)
    which easiely outperforms 2 G4s.....

    Hey, not all of us have a Pegasos just for running MorphOS you know. SMP works very well in GNU/Linux even though I suspect MacOS beats it since Apple pretty much only sell SMP-boxes in their G4 PowerMacs.

    Linux on a Peg ? HERETIC!!!!! ;-)

    But, who would buy a Peg2-2xG4 for use with Linux ?

    Price would probraly be allmost as high as Apple's smallest G5
    (due to low production-numbers), performance would be worse.

    It also couldn't compete in the "cool-runnings".

    There simple is no market that would make such an endavour
    profiable.

    I ranted about this subject on ann (a long time ago):
    http://www.ann.lu/detail.cgi?category=forum&file=1045927640.msg

    Not that I know what I am talking about though ...

    MorphOS is Amiga done right! :-)
    MorphOS NG will be AROS done right! :-)

    Such a computer would be a real beast, like the legendary Voodoo5-6000.

    Give me a working GCC3 for MorphOS/PPC so I can use Boost (http://www.boost.org/) and STLport (http://www.stlport.org/) and I will use MorphOS a lot more than I do now.

    It is absolutely not true that buying/building a system with 1 fast
    CPU is cheaper than doing it with 2 mediocre ones.
    I give you an example: Xeon 2.8GHz is 349 EUR at Alternate and the
    3.2GHz version is 869,-. Likewise the 1GHz 7447 is 178.08 USD at Arrow
    while the 1267MHz version comes down to 357.75.
    PPC needs no special motherboard redesign or different CPU types, in
    fact the Pegasos is a "Dual PPC Board" already and this has been one
    of the original design goals of bplan.
    There could even be a kind of universal CPU card where there is space
    and soldering points for 2 G4 and according to the demand you could
    place either one or two PPC on the card in actual production.

    If the Pegasos starts to gain interest as a server there will also be a demand for dual CPU's. Hopefully the server market will see the benefits of using a cheap non-x86 system soon. :-)
