Guys,
----------------------------------------From what I can see - there's no GPU work available at this stage. If I have this wrong let me know. My farm here at home I have 4x PCs, and a total 8x GPUs (4x GTX580, 2x GTX560Ti & others). Some serious GPU number crunching. I would really like to be a part of this project. My GPUs have been a part of other distributed computing, and have significantly smashed rankings on the project I was previously on. I think it's inefficient if I just dedicate CPU grunt and leave my GPUs idle. If there is work for GPUs - I'll be back. I guess the purpose of this is to highlight 'the powers that be' that's there's GPU resources available in the wings if you can use it. -- Craig [Edit 1 times, last edit by Former Member at Dec 18, 2011 3:45:04 AM] |

Hello zzcmeyer,
We hope to run a Beta test for a GPU version of Help Conquer Cancer early next year. Nothing guaranteed, but work is going on. Lawrence |

Sweet. I'll check in early next year to see how it's going. All I ask is the announcement is easily found :)

Hopefully zzcmeyer, there'll be a new section in the forum's, exclusively for GPU crunching...

zzcmeyer, for now you could use your NVidia GPU's on one of several useful projects:

You can very well connect your machines to two projects, one like WCG using the CPU and another one using the GPU like GPUGrid.
----------------------------------------I did this last year and it was working perfectly well. The only problem is the added power consumption and heat was incompatible with my setup (15 machines into small basement room). My priority being WCG I stopped crunching with GPU's for the moment. I know that when GPU crunching will start on WCG I will need to rethink my small farm. Until then CPU crunching is king.   |

Perhaps I can contribute an idea to that point. But it works only in case you live in a cold part of the world:My PCs do both WCG and GPUGrid, but only in the winter. So I don't need any (other) heating of my flat!   Ask not what the world can do for you - ask what you can do for the world. |

Dieter, I already heat my basement with my machines. The problem is that in that small basement room I have also other stuff and I cannot have a too high average temp in that place. If I could empty that place and have only machines then yes I could do much better.
----------------------------------------In summer time I have to switch off many units unfortunately. |

Over at Malaria a guy is switching his machines over to liquid cooling and says he has SIGNIFICANTLY dropped his temps! "At the moment the gpu's are burning at 78 and 69C and the liquid after kooling is 57C versus 72 to 97C for the air cooled ones." A 20C drop is ALOT!!! He is already liquid cooling his cpu's and is now adding his gpu's. Malaria does NOT have a gpu app so he is using them elsewhere. Also alot of people find they get MORE output of their gpu's if they dedicate one cpu to each gpu, NOT crunching with the cpu at all! I have not yet done that, but it might reduce the heat and electricity usage a bit.   |

"At the moment the gpu's are burning at 78 and 69C and the liquid after kooling is 57C versus 72 to 97C for the air cooled ones." Yes, liquid cooling is it! But one should not get the impression that it is necessary for GPU crunching. At my i7 2600 @ 3.4 GHz CPU temperature is up to 80C with WCG, a new NVIDIA GTX 580 with GPUGrid works at 70C, all with air cooling. Other GPU projects might stress the GPU a lot more. IMHO 100C is near a limit to grill the GPU. So you have to monitor the temperature of the GPU and throttle it in case it gets too hot (for instance by 'TThrottle'). In addition you have to blow out the dust after several months. But indeed, I'm dreaming to have liquid cooling. Better than water would be a combination of both, liquid and air: liquid air!  And best . . . liquid helium?  Ask not what the world can do for you - ask what you can do for the world. [Edit 1 times, last edit by Dieter Matuschek at Dec 18, 2011 4:57:17 PM] |
