Guide to running multiple GPU work units

as always, YMMV

This level of variability is a very recent phenomena with the GPU WU though. WCG used to be incredibly simple and straight forward. :ohwell:

But they're a very collaborative bunch, so hopefully we'll see even these things simplified to that standard.

Yeah, I thought F@H was the "difficult to set-up" DC project. :laugh:

I gave up on multiple work units in favor of consistency.

If you have any problems getting BOINC to recognise more than one card, go to the data folder (Usually: C:\Program Data\BOINC\) and edit the cc_config.xml file to include the following line:

<use_all_gpus>1</use_all_gpus>

Not needed normally, but just in case you do have problems, this is what you need to know.

Got it working with my GTX 470 and GTX 465 in my FX-8150 system, thanks!

So can someone give me the app_info file that works for HCC CPU and HCC GPU on AMD cards w/ the newest 7.05 WUs?

Here you go. Make sure to change the coprocessor count, CPU is set to use full cores. Will add to the OP too.

Thanks a ton!

My cache will be empty in a few hours, so I'll do this after class

On one of mine PCs (i7-920/7770/GPU only, 3 GPU at the time, Ave Turnaround (tbf) 1,608.58) with version 7.0.28 and 3 days buffer I have anywhere from 1 to 12 GPU WU ready to start at any given time). A few hours is pure luxury

On top of that my internet is on and off these days. I can't wait until I install my new 7950 tomorrow.... :twitch:

This was just running with no app_info file (and it has a few hours of CPU WUs left--the GPU is already idle).

We'll see how things go w/ the app_info and whether it will keep pulling down new WUs.

[Ion] · Nov 14, 2012

Well, I think I'd call this a success. I was running 1 WU at a time, and it was completing in about 5.5 or 6 minutes (HD7770). Now I'm running 3 at once, and they're taking about 9:30 each :toast:

Now to make sure that it's going to keep getting new work as it submits the finished stuff--I'll keep a close eye on it today and see :toast:

All of the .XML files I have tried throw errors now on both my cruncher at work and at home :/ I guess its back to using the 2600K only and one GPU

With the new HCC ones my average is 6:55 (timed to be around 9 sec longer then recorded) with three. 3.5 GHz, slow HD, no CPU units, 3 at the time. I didn't time the rig that runs 4 at the time but my estimate is just less then 9 min so no big advantage in going up in numbers on a 7770. Both figures is without running GPU tasks in the background (games/video/general surfing). Is your 9:30 achieved during normal PC use?

I will do the same exercise (3, 4, 5 and 6 GPU units) with my new 7950 tomorrow on the same 3.5 Ghz CPU. I know that the card can run 10 and even 12 at the time (Source: KieX) but I like to keep my temperatures below 55 C and my office is just next to the room where my wood stove is burning.

EDIT: Going to try 7.0.38 and see if it helps.

EDIT2: Still doesn't work. I can't believe BOINC will only use one GPU if it is "superior than the other." You would think they would want the most output possible???

So I put my 7770 in the same machine as my 7950 and the 7770 is reporting as "not used" when I specified <use_all_gpus>1</use_all_gpus> in cc_config.xml. Any ideas?

What's your exact cc_config file text? And I assume you hit "Read config file" after adding it? And where did you put it? It looks like BOINC isn't seeing the instructions to use all GPUs

Can you copy the errors you get? If we coincide on FB or something can give you live help too.

Can you post a copy of the cc_config.xml? If it's in the file it should appear in the log.

Huh, can't believe I did a stupid mistake like that. Well, after all the trouble I have the latest beta BOINC version and 2 GPUs working. I appreciate the help KieX (and Ion, didn't see your ninja post until now)! :toast:

No worries. :toast:

Time to sit back and watch them roar now :rockout:

After following o3m's and manofthem's guides and .XML files I have 6 WU per card on the 6950's!!!

[Ion] · Nov 15, 2012

That's awesome! Keep us posted how long they end up taking--those preliminary results look incredible!

t_ski · Nov 16, 2012

So are there any other projects that can utilize GPU WU's?

Unfortunately, HCC is so far the only one.

t_ski · Nov 16, 2012

Thanks - that's what I thought.

[Ion] · Nov 16, 2012

Well, I had my first issue where the GPU WUs just get "stuck" and don't do anything. I lost about an hour while I had two just sit there and spin...I aborted them. Any idea how to avoid this in the future?
