Hypernova, looks like others are following your lead and using computers to heat their homes. 2 months ago all you needed was to crunch 100 days of CPU per day and your were in the top 50. Now you need 10-15% more.

It was minus 30 here in my section of Canada,
----------------------------------------but since I was in Israel WHO CARES. now i'm back and it's a balmy -7 (19F) Tshirt weather. Well got all my machines goin at it, but it doesn't help too much to warm the basement. Still though, sounds like a great excuse to find another computer, giving away one of 4 to a friend who just needs an email machine (with the understanding they let it run WCG of course).   |

Hypernova, looks like others are following your lead and using computers to heat their homes. 2 months ago all you needed was to crunch 100 days of CPU per day and your were in the top 50. Now you need 10-15% more. It is a never ending competition. Keeping your position in this fast changing world is already a big feat. The problem with heating in Winter is what to do in Summer. When temps are under zero it is possible to cramp up to 18 boxes in a very small room if the window is large enough. But in Summer the maximum is 8 boxes. Then I have a big problem. All those machines idle. That's a mightmare. Sure power consumption goes dramatically down, and compensates for the crazy consumption in winter. It averages the overall yearly cost.

All such problems would be immediately cured via a move to GPU's:
Your eighteen part time 8/12 thread systems at 250W each do around the same as one GTX580, also 250W. So one or two good systems with a couple of good GPUs is plenty for any home contributor. I also think there might be a problem with that 90degC CPU. I would first check to see if one of the heatsink clips has come lose and make sure turbo was off. If those things are OK I would make sure the fan is running properly, look at getting another exhaust fan, and perhaps take it out, clean the surface and reseat it. |

So one or two good systems with a couple of good GPUs is plenty for any home contributor. I see very well were you want to go. Your reasoning is ok if the aim is just points or credits. But if the aim is contribution to WCG projects (points are a only a side effect) then unfortunately there is no GPU crunching possible. But as you know I have added a few boards to contribute to GPUGrid. The reason I did that was not points, but what convinced me is a certain number of simulations that were eye openers at least for me, a completely new understanding about how the molecular machinery does work inside our cells. And it is that fact that convinced me to contribute. I find GPUGrid and WCG very complementary, thus my decision.  As I said again best of both worlds  |
