    Damn, 5 work units already. You're fast.

    I'm Rikusaki by the way. I've been folding for a very long time, but you'll catch up . ;)

    Not me, the GPU is doing all the work. I might tinker with the SMP client this evening and see if I can get it doing something useful too.

    Waaaaay back in the mists of time (when a 400MHz Pentium II was cutting-edge!) I was part of a team doing something similar to crack RC5 encryption. No GPU cleints back then - it was all done on single-core CPUs, apart from a few guys who co-opted SMP servers at their work for illicit overnight runs. :)

    I installed and configured the SMP client this evening and it's currently running through its first data set. With all four CPU cores @ 100% utilisation the system is still perfectly usable and CPU temp has only risen 7C above idle level. I'll run the GPU client alongside it overnight and look at the logs in the morning to see how they play together... may have to back off the "CPU Usage" slightly on the SMP client to avoid throttling the GPU one.

    Already thinking about resurrecting my old Athlon X2 purely as a folding rig. We might get a few weeks work out of my 8800GT GPU before it finally croaks (and I can contact BFG about a warranty replacement!) :D

    Haha, nice! I'm actually using a factory overclocked version of the 8800 GTS-512. Nvidia cards seem to do better at folding because of CUDA. That 8800 would be a great addition to the team. :)

    I might fire up an SMP client as well. I have a Q6600 overclocked @ 3.4Ghz.

    Those puppies were built for clocking - mine is an OC2 variant from BFG.

    I think the latest ATI client uses DirectCompute but that little 8800 was a cracking video transcoder using CUDA routines in MediaCoder.

    It's a blast-from-the-past.... CLI config etc but a cinch to install thanks to the clear guide available on the F@H site. Be aware though that it uses "big" WUs as the default and mine is currently churning through 500k steps!
    1h20m in and it's at 14% completion.....

    Yeah.. I have another old 8800 GTS 320.. Might stick that in one of my older builds and use it just purely for folding.

    What the.... You jumped from 8 to 132 WUs overnight?! How did you do that? That's insane!

    I am going to try to get on with my PS3 tonight. I am copying this info and hope to give it a go.

    It's bogus - notice how the points didn't increase much?

    Each run with the SMP client aborted with an EUE and took the core with it, which also messed up the GPU client. So I installed the uniprocessor CPU client hoping that would be more reliable. Guess what....? Every run (on a single CPU core) also threw up EUEs but some sort of data was returned each time. I think that's what has inflated the WU count.

    p.s. found the ideal folding rig last night. Check this bad boy out! :D

    Oh, lol.

    Also, the link you gave me doesn't work.

    "The product you have selected is not currently available for online purchase in the segment you have selected."

    Ah, must be UK-specific or sommit. It's a Cray CX1-iWS with:

    Windows 7 Workstation: 2.26 GHz Low Power Intel Xeon L5520 Processors
    Windows HPC Server 2008 Cluster: 2.93 GHz Intel Xeon L5520 Processors

    Yup, that's right.... 24 cores of Xeon goodness! Yours for only $55k! :eek:

    Wow.... I bet that rig would put us in the top ten in no time!

    Lol, oh man.. You're already at 400 work units? :p
  14. PaulMcCartney

    PaulMcCartney Well-Known Member

    Now you're over 800! Damn.

    Nope, now 1100+.... :D

    In addition to the GPU client I had three standard systray clients running overnight, two on the GROMACS core (one using >10MB work assignments and one not) and another on the ProtoMol core (using -advmethods). One of the GROMACS projects involved very unstable models and most were EUE'd within a few seconds of the simulation starting. Not very productive points-wise but hopefully will assist the boffins with their work.

    Nice! Keep it up. You're doing great. :) Our team moved up 10 positions in the last 7 days. Let's break into the top 1,000!

    The 8800GT is a no-goer I'm afraid. It isn't able to run any projects for more than a few minutes before the client shuts down with "NANs detected" errors. Furmark and OCCT's DirectX stabilty test don't show any artifacts or failures and F@H doesn't stress it anything like those two, and it's even behaving from a cold boot, which is a bit annoying as I need it to be consistently failing to RMA it. Plus it would have added another few thousand points to the team. :(

    Is it the same work unit failing over and over? If so, delete the queue.dat, work folder, unitinfo.txt and that should make it download a different WU.
  19. Slug

    Nope, I think there's simply a minor problem that only becomes major when folding. Maybe failing VRAM, maybe shaders on the way out, maybe it just hates me.... I'll maybe leave it on the bench rig running Furmark overnight and see if I can kill it. :mad:

    Lol. Good luck.

    Hmm, Lady Luck is a fickle mistress.... :rolleyes:

    The cursed card survived 7.5hrs of Furmark unscathed, and is currently 52% through a GROGPU2 wu. If it's developed the 'bad solder' problem that plagued the 8xxx-series then perhaps keeping it working hard will stop the joints cracking?

    Some bad news: the a3 core crashed ("program has stopped working" msg from Win7) just after I woke up this morning and I lost a 2500pt wu - checkpoint didn't work for some reason. :(

    update: woohoo, I think it's finally died! :D

    Aw, that sucks.

    On the bright side, out team is moving up quite nicely. :) We should push hard to break into the top 1,000!

    Nononono, it's good.... means I can get it RMA'd. If I'm lucky I may get a 260GTX in exchange, depending on what stock BFG have left.

    I saw we'd climbed another few places today. Go team!
  24. PaulMcCartney

    PaulMcCartney Well-Known Member

    Oooh, lol. :p That's cool! A GTX260 would be awesome. That card is great at folding.

    It's 65% faster than a 9600 GT (Don't know why it says "Pro" instead of "GT")

    It's a crapshoot what actually arrives back, and won't be helped by BFG's announcement that they're ceasing graphics card production completely. I might be 'unlucky' and get a borked 8800GT back if they find one in a dusty cupboard, of course. A friend played GPU ping-pong with them for three months until he got a working replacement for his 9800GTX.
