That's the part I fear the most as well. If not for that I could throw a fair number of cores at the issue.

Sounds like a plan.
I had my eye on all the boxes that were recently replaced at work...only core2 duo's and only stock but there were 150 of them..... alas I now have a tear in that eye as they were returned to HQ
I'm pretty sure my syntax is shot to hell, but you get the idea. ;)Quote:

SC Week Loaner Club? I like the idea.Quote:

Perhaps you should. Wait... yep. You definitely should!
It breaks my heart: my contract ends at 31st October and I am not sure about machines I am leaving at the Uni :(
Hopefully they will crunch happily in the corner until the next person goes through and wipes them :D
My SC week plans include getting any machines I can together.
new plans: get a motherboard and some AMD gpu to go with my i3-2100/ram/case/psu, plus convert ALL gpus in my sig rigs to WCG HCC GPU!
The electric bill is the bane of my existence!Quote:

6 GPUs in one computer would be freaking awesome... but 4 would be acceptable. :p:
thanks. I would probably go for a standard ATX board... 2-3 gpus with at least double or triple space if possible.
updated plans: switch over my 5x GTX 660 Ti cards, 2x GTX 470 cards, and 1x GTX 650 to WCG HCC. Also I will have another GTX 650 Ti by then as well. And I will move the AMD 7850 to one of the i5 quad cores so I can run 3 tasks at a time.
Depending on the money situation:
Buy a used quad core system
Or
Buy at least one HD7770 or HD6870, move the HD6670 to the Dell i5 and put the Seasonic 650W PSU I was saving for a new build into the Dell.
Or
Find someone who has computers on XS and donate some $$ for their rigs electricity
I assume that MM will send an email this week to all members and to make it easier for them to participate I suggest preparing NEW STICKY for new-comers. Stickies that we have may be a little "intimidating" with 200-300 pages. Also, no secret that GPU crunching is best thing since sliced bread so maybe quick guide with screen-shots to help the transition.
I guess that 50M is more than possible with all GPU power that XS members have.
:D
Don't forget that GPUs are not the best thing for EVERY kind of problem and they do have some weaknesses regarding heat and duty cycle that we are so used to dealing with on CPUs that we forget about them. Tesla cards, which are dedicated GPU compute cards (not high end graphics cards like one idiot tried to claim), are built to run at full load for extended periods without cooking themselves while consumer graphics cards aren't expected to be run nearly as hard let alone 24/7. Taking a few simple steps to keep temperatures low sounds so obvious that nobody is mentioning just how hot GPUs can get without a little thought. The fact that there is only one science app at WCG running on GPU is a good indication that not ever project is suitable for GPU implementation, either. Some will benefit greatly, others not so much. There could even be some that just can't be run on a GPU at all due to a lack of functions in the hardware.
There is whole bunch of people out there running running bitcoin, f@h or boinc project on gpu for years and I think they can handle one week of WCG :)
Those are people who are already familiar with GPU crunching. I'm trying to get the point across that this isn't points for free. There is always a price to pay somewhere. If you're aware and understand the risks and requirements then it's all good, but this isn't for everyone.
... and things like these should be clearly stated in a guide for new-comers :up:
