Excellent -- having an alternative ATI GPU project will make life simpler for Slicker at Collatz when he returns from his vacation (I think that will be Monday). As it is, Collatz appears to have crashed and burned for now -- possibly something Slicker can't fix remotely.


I really don't know how the us mail works, but the hard disk here in Europe had arrived days ago. I am not in hurry of crunch MW, just ponder.


The hard drives are here, they just need to be installed. I'm going to bug labstaff tomorrow to hopefully get things working again.

Yep Collatz is down as well.

My 5970 has arrived so I will install it tomorrow. Really looking forward to see what it can do.

My water cooled box will be ready on Sunday as well, so I can crank Cosmo up on that, hopefully, without the constant cpu shutdowns. I don't really understand how two projects can use 100% of the CPU but have such different effects on the core temps.

My builder has come up with a plan to 'spin' my office 180 degrees and put the crunch boxes in the garage to get the heat away from me, so things are looking good overall, ignoring the power usage, of course.

How's the production on the 5970? They may have hit on the perfect DC formula here. Everyone gets equal credit/day and no excess energy usage. It's revolutionary!

It makes a really great whirring noise as the turbine fan spins up, and then it has been quiet ever since while we wait for WU's lol. And its got a neat red stripe down the top of it to match the Sata cables. hehehe.

Hopefully it won't cost too much, I will find out tomorrow, when I have to pay for it, and the water cooling experiment.

Personally I don't see how anybody could complain about the crediting on this project. Cut it half... still be more than any other project.

Cut it in half? Ouch, that would be painful. But so long as it cuts my electricity bills in half, I'm up for it.

I see many differences between projects some do not even heat up my cpu's others i see which are memory intensive tasks heat up my cpu more.
Ofcourse it also depends on the optimisations used so in fact to many factors to mention.
Its like running collatz on my 4770 gpu card which make it 64C but when it runs MW it becomes 79 or even hotter.

Its new, its relative fast... my new bicycle

What a ridiculous statement. There are many projects that pay a lot better than Milkyway. Collatz, GPUGRID, Seti BETA just to name a few. Check out the facts before you make such blanket statements.

I don't know in what framework you mean this but I'll assume we are still talking about GPU apps.

I run 3 of these 4 (no "Seti BETA"). I'll take numbers from FREE DC as of 10pm central today in the order you listed:

THE FACTS:

Collatz, 1 GTX-260 card + ~25% of the HD4850: 63.7K (avg 52K)
GPUGRID, 9 GPUs, from GTX-275 down to 9600GSOs, mostly GTS-250s: 80K
MW, ~75% of 1 ATI HD4850 card: 55.6K

So let's evaluate/rank these.

MW - 75% of 1 ATI card produced 55.6K so far today or 74.1K/gpu
Collatz - A GTX-260 + 25% of the 4850 produced 63.7K (but averages 52K) or 51K/gpu
GPUGRID - 9 cards produced 80K so far today or 8.9K/gpu

Now it may seem "What a ridiculous statement" to you but I'm still waiting for you to name one project that produces more credit per GPU than MW.

Suggest you take your own advice "Check out the facts before you make such blanket statements."

Could it be because MW does FFTs and Collatz doesn't? I don't know, just throwing that out as a possibility.

You cant compare different kind of GPUs... its like stating "my Phenom x4 955 in XXX makes more credits then my Athlon 1400 in YYY, so XXX is the best paying project..."

Actually I can. Let's say for a moment that your T-bird produces x credits on project YYY and your X4 produces 2x credits on project XXX. Who pays better credits? How did you reach that conclusion?

Anyway, where I was headed was...

Whilst out credit whoring around looking for the cheapest way to just add credits to the team output, I have come to the conclusion that you can do no better than throwing an ATI HDxxxx card into a Windoze machine and pointing it to MW (let's keep the cards to say, sub $200 or perhaps even sub $100).

Acceptable? Is there another answer that I missed?

If not, then I still believe my original statement. MW pays the highest credits for effort/money expended.

Ever since I convinced the guy at the corner store that BOINC credits are valuable and he lets me traded them for merchandise this became important.

If you take the best credits for initial expenditure i.e. purchase price your right.

If you factor the electricity bills into the equation I'm not so sure :)
4770's still may hold. Anything with a 48xx or 5xxx well thats a whole other story.

Yup.

I had bought a 4770 when they first came out but never did get it to crunch MW. I thought I'd read that somebody here did get them working but it was after I'd RMA'd mine. MW & a HD4770, that would be the ticket w/o making as many offerings to the electricity gods.

My framework is, your facts are revelant to ONLY you. Your statement '...how anyboby could complain..' applies to me. The projects I mentioned pay better for ME. Your reply to Sailor's post, validates my point. With GPU/CPUs performances all over the map, everybody's facts will be different. Your statements assumes everyone else in the world is just like YOU. Ridiculous, yes?

Looking at your host via BOINCStats, you appear to be using your GPU at Collatz, but CPU here. Perhaps you are unaware that this project is CUDA-capable now, or that perhaps your specific GPU is not capable of running here. In either case, you're comparing a faster GPU against CPU performance. Of course the GPU is going to be faster and get you more credits. What's being said is that if you compare "apples to apples", credit is higher here than with other projects. This is true. It may not appear true to you based on the difference of using CUDA somewhere else and not here, but when evaluated objectively the credit per unit time is better here in most (if not all) cases as far as CUDA, and definitely better in all cases in regards to ATI on credit per unit time. People also get caught up into just relying on RAC to be the be-all-end-all determination of which project gets higher credit, but disregard that if you aren't at a 50/50 resource split and you have work fetch problems at one project (MW), but not the exact same work fetch problems at the other project (Collatz), one project could appear to get higher credit based on the relative viewpoint...
