Have you got pie today?

[Jstn7477]

Yeah, I don't really want to go back to 7 on my desktop (all the other crunchers still run 7 or Ubuntu 12.04 LTS). AMD's drivers still suck under Windows 8 as well and I get a BSOD every 2-3 days with AMD's typical Kernel-Power event BSOD or whatever it is. My 7950's fans still turn on/off randomly when the computer hasn't been touched for a while, and they make an extremely annoying jerk/shudder noise every time they turn back on in the middle of the night.

Anyone know how many WUs a GF104 or a GF100 can run, and is it easy to set up 2 cards to crunch along with the CPU? I don't want to move off of F@H completely, but I probably should have jumped on the HCC GPU bandwagon from the get-go.

If they are working for a good cause, it's doesn't matter too much which, does it?

So do what you want to. It is your hardware after all.

Yes, I wish I could run everything under Win8, as I'd rather run everything under that. I guess it's just a waiting game til everything works there.

I haven't had too many AMD driver issues under Windows 8 other than the WCG difficulties, even running crossfire.

Congrats to All of our Crunchers!!! -

Geez! Getting into the top 20 now requires some serious heat! Superb job!

[hat]

Yeah, even I only see myself in the top 20 with I've gone away for a few days for work. Turning off gpu crunching and sacrificing cpu power to Borderlands 2 while I'm home is enough to get me kicked out of the top 20.

Planning to try this later. Only got 15 more minutes before leaving for work.

For 3-4 cards you would need to do that on a Dual Xeon/Opteron board though (need the cpu cores to run all of that)

Imagine the ppd!

For three cards, I might be able to run four WU's each on my 3930K. If I had a fourth cards, I'd have to run no more than 3 WU's each. But yeah, if I ccould run 6 WU's each with three cards that would need 18 cores/threads. Dayam...

In the app_info file there is a ncpu setting to allow for that:

<plan_class>ati_hcc1</plan_class>
<avg_ncpus>1.0</avg_ncpus>
<max_ncpus>1.0</max_ncpus>

Leave the max_ncpus, that just says how much to use if available. The avg_ncpu line specifies how much of a thread to use on average:
Total CPU Threads / Desired GPU WU Total = avg_ncpus

With setting of 1 it's meant to use whole thread. To run 4 GPU WU on 4 GPU with a 12thread CPU that would be: 12/16= 0.75

So to run 3 GPU WU on 3 GPU with a 8 core/thread CPU that would be: 8/9=0,888 ?

Thank you KieX!

Be forewarned, the nV GPUs just don't do that well. The GTX460s in particular...they do ~50% of the WCG PPD of the GTX470s. No idea why

That's a bizarre issue to have. I don't think there have really been any successes running multiple WUs on nV--Buck got something working, but I think he had persistent issues

There's a guy at XS that's running a standard quad-core i7 with eight WUs on a HD7950. Absolutely amazing. He gets 100k+ PPD from it too o_o

Im running 2 Wu's per 680(have been for a few days, no errors), not so bad but clearly not in league with AMD's

I'm running out of Patience.

Thank you KieX!

Yup should do the trick. Not tested it myself but that's the consensus based off the information from others using it for WCG.

So half the day is over and it looks like it's going to be a fight for a piece of pie.

Great job to every one!

/QUOTE]

I tried on my 680 but it only lasted for 2-3 hours and then I ran out off WUs but it seems like some people with 470 get some decent return and it could be because they got more luck then Buck and me so don't give up.
Edit As Waternub said it can be done. I failed the first 3 times on my AMD so don't learn by my experiences.

It's getting really hard to get the pie

[Jstn7477]

So the consensus is that WCG runs better on GF100 than GF104 due to the architecture differences I assume? I think I might move my 470 to its own system tomorrow and try it out on WCG. I want to move some GPUs around anyway.

Indeed so but I think I have the solution........ 7970s FTW! (at least for now )

I'll gladly share if anyone wants to take a piece

I've been trying but to no avail, gotta be Superman to catch up . Man, if only I had a 3970x and 4 7970s....

It looks like you've been helping yourself to some pie quite nicely

Wow--amazing job everyone. Halfway through the day and more than 30k points required for pie. It's gonna be close tonight!

Yes. I get ~14-15k PPD per GTX470, and ~half that per GTX460.
