Not that I know of. Only one task per card. BUT I can say that some units are better utilizes than others, as with the card running at the exact same GHZ and voltage, the temps can vary really high on some unitsA pro pos 3500 cuda cores: Is it possible to run two F@H jobs simultaneously on the same card? Depending on the WU type, a single job utilizes the GPU more or less below full tilt. The bigger the card, the lower the average utilization it seems.
Actually this 2620v3 seems to be doing quite fine as F@H triple GPU feeder. From what I remember, GPU core utilization and PPD were quite similar with the i7 before.my four GPUs shall crunch some extra rounds in Folding@Home. The GTX 1080/ 1080Ti's may underperform though because their 4.0 GHz feeder CPU had to be replaced by a 2.6 GHz one.
This thread has nothing to do with curecoin, only FAH. Please start your own thread.Hello all. Wonderful discussion you all have going here. I once folded a long time ago for a while, but got away from it (and SETI, and wcg...). I'm finally getting back to where I have some time to devote to it again. Currently, I've got some old phones and a few clunkers rotting into obsolescence while cranking out SETI packets and a phenom X6 doing WCG work. As the result of a recent project, I have received a handful of Intel I5-2300 boards with RAM, a bag full of Nvidia NVS 510 video cards (underclocked GT 630 2GB DDR3 128 bit), and a few spare drives and a case. I have taken that case and installed one of the motherboards, 16GB ram, and two of the nvs 510 video cards. I fully realize that the video cards are old and slow, but this isn't really meant to be a prime crunching rig.
I would like to use this as a "proof of concept" box for making a farm of curecoin miners. The boards are low end, with one pcie2x16 slot and one x4 slot and no overclocking, but they're free. The power is free to me for the next 6 months or so (solar array at work, currently out of production due to age and production related issues but still power certain outlets while it waits to be replaced. I have permission to use it at my own risk) and the internet is public wifi from next store. So, cost and environmental impact are not a concern.
So, here's the question: how best do I set this up? I plan to use linux (mint is my weapon of choice). I have no experience with coin mining or the wallets associated with it. What are the gotchas? Does anyone know any setup guides? Given how low end those cards are, can I get away with running a cpu process or two as well?
Any insight would be greatly appreciated.
Folding@Home's credits are nonlinear: Amount of work is given credit too (like in almost all other distributed computing projects), but there is additional credit for how fast the work is done. Simplified, a fast card can be better than two slow ones.I have received a handful of Intel I5-2300 boards with RAM, a bag full of Nvidia NVS 510 video cards (underclocked GT 630 2GB DDR3 128 bit),
First, what linux tool can you use to see GPU temps, and utilization% ?On the question how much GPU performance in Folding@Home depends on single-threaded CPU performance:
GTX 1080 Ti, driver version 384:
- Linux, i7-7700K, 4.4 GHz:
GPU utilization 94...95 %, 1.1...1.15 M PPD
- Linux, E5-2696v4, no load besides F@H, 3.4 GHz:
GPU utilization 92...94 %, 1.1 M PPD
- Linux, E5-2696v4, WCG besides F@H (3C/6T set aside for F@H and OS), 2.8 GHz:
GPU utilization 88...93 %, 1.05 M PPDConclusion: CPU performance does matter for GPU performance in F@H, but not as much as I initially thought. The influence of the operating system is much higher than the influence of CPU performance.
- Windows 7, E5-2696v4, 2.8...3.x GHz:
GPU utilization ~75 % (rarely ~80 %), 0.85...0.90 M PPD
I've heard Linux folds faster than Win7, guess they weren't kidding. I'm an old geezer who'd like to maximize my folding but can an old dog learn the new tricks of Linux? My folding rigs are headless & Win7 TightVNC makes that easy to do. Is there a good book or resource I can use to break the Linux ice??? TIA(...extra packages which I installed on Mint was Openssh-server. That way I can use an ssh client on my main PC to log into a command line on a DC worker PC, for example to run tools like nvidia-smi remotely.)

Well that was close, but I had to tweak it to work for me. Check out my procedure, based ont that thread in my "help with linux" thread.I too am an old geezer............... If I can manage to do it pretty sure you can too. Look HERE for install guide, follow to the letter and you should be good to go.
What Tony said. But besides psensor, I also use something like
nvidia-smi dmon -d 120in a console window. This shows power usage, temperature, core utilization, memory utilization, and clocks, every 120 seconds. See "nvidia-smi -h" and "nvidia-smi dmon -h" for more options.
(BTW, one of the first extra packages which I installed on Mint was Openssh-server. That way I can use an ssh client on my main PC to log into a command line on a DC worker PC, for example to run tools like nvidia-smi remotely.)
