    Bringing FAH back...

    FAH is to much work for me to run on my cluster of systems but I do have two GPU heavy systems that can run 24/7. So far I have switched one over and if I don't have any issues I will switch the other one over. These two systems are hitting over 36K blocks a day in RC5-72. I also have an HD4870 ready to put into a system to add to the mix. Who else is with me for a FAH revival?

    glad to see you back guru.

    fah sure gives a lot more points than the old days.

    except for a couple breaks been running fah since 2002.

    I'm running three GTX285 in each system. Both are running 1KW powersupplies but one seems to be a little weak. RC5 running on the GPU's pulls about 705W and is stable. FAH on all three GPU's pulls 730W and shuts down after a while but is stable on two GPU pulling 560W. I have a newer 1KW power supply that I will be swapping in later this week. After looking at how slow the ATI clients run on FAH I think I will put it on RC5 since it is about twice as fast as a GTX285.

    Got two gtx-460's on it and very shortly will be 24/7 as the temps here in vegas are finally going down.
    Yeah, you certainly get a lot more points compared to the old days.

    i'm going to be running folding@home until the day i die as far as i'm concerned. hopefully we will make some kind of a difference.


    Fold moar!

    I'm adding two more GTX285 and GTX580 part time. Got the new power supply in and it is working great, 900W of 12v power. Total of 8 GTX285 and one GTX580.

    After playing some with the new SMP client it looks like it is a lot easier to run on many systems with more then one core. And so I am releasing it on my CPU minions.

    I'm a little disappointed in the PPD of the GPU V2 on my GTX285 cards. My I7 2600 @ 4.8Ghz is getting ~17.9K PPD while two GTX 285 get ~17.6K PPD. My work I7 3Ghz running 8 cores (6 core 12 thread) is also hitting 17K PPD. Cost and power I would put the I7 2600 above any GPU. My GTX 580 is only hitting around 16K PPD.

    " I7 2600 @ 4.8Ghz is getting ~17.9K PPD "

    that is on my wishlist. i think i read those are capable of over 40,000 ppd

    It seems to be slower then my I7 930 @ 3.5Ghz. Both are running GRO-A3 cores but the 930 runs ~4-5 min per step while the 2600K runs ~6-7 min per step. My only guess is the triple channel memory is helping more with the large units then the CPU core speed. DDR 3 1333 triple vs DDR3 1600 double.

    Bringing f@h back? Did I ever leave? Been chugging along with a GTX 260 for a long time now but recently upgraded to a GTX 460 with shaders @1660MHz. Trying to run as close to 24/7 as possible which gets around 11k PPD.

    guru, make sure you're running -bigadv on SMP machines which are capable. I think it requires 8 core minimum and a whole bunch of RAM, but don't quote me. It's worth a lot more points than standard SMP units but the deadlines are quite restrictive, IIRC.

    Thanks Alpha. I do have my 8 and 16 core systems running -bigadv. Once I get the rest of my minions up and running we should be able to hit 1M PPD.

    wow guru, you passing us like we're standing still.


    oh and, folding@home sure makes these video cards run toasty!

    FYI, there are upcoming changes to -bigadv:

    http://folding.typepad.com/news/2011...y-16-2012.html

    In short, you're gonna need 16 cores minimum.

    The problem is thread count alone does not dictate system performance. My 8 core systems were completing the large units in under a day. A 3.4Ghz 8 core can rip through a WU faster then a 2ghz 12 core.
