Interesting Folding Observation

    If you go to the folding at home stat page, there is an option to view stats by OS.

    Doing a little math:

    Windows: 337,558 WU / 81,779 processors=
    4.13 WU/processor

    UNIX: 32,129 WU / 4413 processors =
    7.28 WU/processor

    Mac OS X: 23,198 WU / 2551 processors =
    9.09 WU/processor

    Does this tell us something?

    Pretty much agrees with what I've seen with folding. I've got a Linux dual P3-Xeon 700 w/1MB L2 and it always beats my dual G4-800. Slower clock speeds, slower RAM, less chip cache, and it still wins. I bet one of those dual G4-1.2 cards could equalize things.

    i'm not seeing how those numbers give any indication of folding speed.

    what it tells me is that the mac users tend to stick w/ folding longer (more WU-production bang per processor buck).

    The only thing I would say is that Mac users are more likely to fold 24/7 than others are.

    The PC users are more likely to play games.

    It used to be that there were more active Mac OS X users, as a percentage, than any other o.s.

    This is true because no one wants to install Os X which RUNS folding, on a >400MHZ computer

    Our per/WU would be alot lower if they has OS 9 compatibality. ;)

    Oops, I read that as "hours per unit". :rolleyes: So basically I read what I expected it to say. Stupid stupid.

    no worries. it was the middle of the night, i was sleepy and scratching my head. "what am i missing?!?!" lol

    Macs definitely don't whip PCs in folding. My Compaq K6-III @400MHz is at least two or three times as fast at folding as my 500MHz G4.

    No one said that at all. :rolleyes:
    Pcs are faster than macs in folding because they can't write the tiner core properly.

    all should be good when we get gromac core tho... they just keep pushing it back :mad:

    Yes that is why we have so many mac members helping out our team.

    No improvements to the Tinker core would suddenly yield 1-to-1 results against a processor double the clock speed. I think people are going to be disappointed that the Gromacs core will not be as fast as expected, even if it will be much faster than Tinker.

    When the Gromacs core is bug-free, they will let it out to the general public, until that time, they need accurate answers.

    Or is it just because G4's and G3's are vastly outpowered by Athlons and P4's?
  13. macrumors 604


    There should only be a 10-30% G4 ~ P4 difference because the Gromac core is Altevec supported, check there web site they have stats.

    Basically there is a poor written code for the whole mac clients w/ Tinker. Plus with good code the gromac gives a better speed boost to the G4.
