GPU or CPU

[Bigred]

They're great, huh? It doesn't seem worth running a CPU on projects where ATI GPUs are supported.

I'm particularly interested to see what the new HD 5990 will be capable of.

I run my ATIs on old single or dual core machines. If I try to run a CPU project on them at the same time I actually get less credit. So on those machines it's GPU projects only. My Nvidias are all running on quads and CPU projects don't seem to affect the output.

The HD5990 should be awesome but unless you run it on an I7 you may spend a lot of time waiting for work. Milkyway still limits you to only 6 WUs per CPU core.

Not sure why that is. I have a HD 4870 running in a Core 2 Duo processor machine. I run work full time on both cores of the CPU and it has virtually no effect on the production of the GPU.

Well, if the 5970 is anything to go by you'll also need to worry about the size of your case. That thing is 32cm long (12.5") and weighs over 1kg!

I'm getting on Milkyway with the HD4870 - 95,000 credits a day
And I to have been running other Dc projects on the 2 cores

I run F@H on a ATI 4850 and no real problems runing Bonk and other projects except MilkyWay which wants to take over and hog everything. Prefer projects with some real, possible benefit to mankind as I'm no longer a stats whore. After IB left, it kinda made me think about retiring from full time DC cos budgets getting tighter and other priorities have arrived as well as electric power (as well as gas) has skyrocketed in price over here and I had to sell my incomplete solar and wind powered bungalow because of planning problems. Didn't really have to sell it, just got tired of fighting.

I am sure we all would say that you Like IB have Paid your DC Due's
So if you feel you have to move on it is OK we just ask that you just stay in touch every now and then

I'm doing some voluntary work when I can but I'll never be off the net or not answering email whatever is going on or wherever I am. Just getting some usefulness out of my brain in helping in the planning of and construction for a specialist college for the disabled which I got "co-opted" into after helping them get their IT and Cisco Academy kicked off as well as pointing them in the direction of "the right people to know" to get some hefty grants and sponsorship. Enough to build a complete IT block with full disabled facilities and some decent living accomodation for students who stay there as well as a facilities centre with fully heated and equipped pool and med centre. We now also have sponsorship from Cisco and Microsoft which will save millions and get real and decent equipment. So I'm going to be pretty busy (unpaid) even if I'm laid up in a bed cos they don't accept lying flat on your back as any excuse for doing nothing as we are going to be taking everybody from autistic and 95% physically disabled (computerised wheelchairs which one of our engineers designs individually) in an age range from 14 to 60 as well as accident and services disabled for the government back to work programs.
So I'll never actually leave you guys, just still contributing a computer or laptops worth instead of the tempting £7.9M of new gear we're getting in the near future as an interim re-equipment to go with the contributed stuff from places including A Free-Dc member who will be nameless (thank you Helix von Smellix where have you gone mate?).
Sorry for the usual bad habit of long posts and hi-jacking the thread but this is my only post until we get our heating and hot water fixed next week sometime so even with an eight core running in here, it's only 5C and I'm getting numb so heading for the caravan to warm up. My trusty old Elddis saved Xmas for us even though it's near 26 year old but the computer has to stay indoors (enjoying the cold and finally running 4.00ghz).
So thanks Lauren and see you guys around. Enjoy the peace and quiet or better still, have some barbecues to keep the winter DC blues away .

I will have to retract this as I have noticed that running DD@home did add 45 sec to the GPU WU's
But these are on X2's so that may be why I get so little drop in GPU output

OK I see Bigred is Right
When running DD full out on the 2 CPU core it drops the GPU Daily total from 95K to 70K
I will try to cut it down to 1 CPU core and see if that helps improve the GPU load Output

Yes It does Leaving one core free is the trick
NO Decrease in output when you leave a core Free handle the GPU

Milkyway now has an official ATI application available. To use it you need Boinc 6.10.13 or above and the ATI9.12 drivers. Just attach to the project and change your MW preferrences to reflect that you want to use the ATI GPU.

Crashes within seconds on my 4770.

Might be because I have collatz running also.
