Guide to running multiple GPU work units

[Chicken Patty]

Any idea what the settings have to be set at on the utility to run four WU's on two 7770's?

Also, do i run a C/F bridge or not?

Bridge isn't needed

Do the following:

add the use all gpus line to cc_config file

in the app_config
use 0.25 on the gpu line (8 total wu's)
use 0.5 or less for the cpu line (depends on cpu)

See code below

cc_confg

cc_config>
<options>
<report_results_immediately>1</report_results_immediately>
<use_all_gpus>1</use_all_gpus>
</options>
</cc_config>

app_config

<app_config>
   <app>
      <name>hcc1</name>
      <max_concurrent>8</max_concurrent>
      <gpu_versions>
          <gpu_usage>0.25</gpu_usage>
          <cpu_usage>0.50</cpu_usage>
      </gpu_versions>
   </app>
</app_config>

Is the cc_config file in this folder/path?

Looks like they are getting loaded up fine. What are max safe temps for these cards? Seen the one that is getting little air is running much hotter.

Yep, seems like it is...

The top card tends to get starved of cool air/pick up heat from the lower card- If you can get a fan in front of the cards it will help a lot

My top card ran in the 70's until I added a fan. It runs around 60 now...

That's pretty bad ass man. I Have something similar but not magnetic in my AMD rig to keep the board cool. Gotta get something like this for the 7770's. Thanks for the link

And suddenly tonight w/o knowing why, my BOINC for MacOS X 10.7.5 started to accept work for my ATI GPU. Strange world cause i investigated quite a bit about it two months ago but found no answer ... and a few minutes ago, watching a youtube video i saw how it was getting slower ... same symptom as it happens on Windows when it's GPU crunching.

Thought it couldn't be that on Mac (it has been running since the beginning of January and the GPU was detected but no available work for it ever) ... but i gave it a try, i just looked at the Manager to double check and found that it was really crunching!!! So excellent news, i don't have to reboot anymore to do GPU crunching on my main rig

It's running multi WU's as well

PS: Any MacOS user who had that issue as well?

With all this talk about using multiple cards, I am wondering if I couldn't put my GTX560 in my rig as a secondary card behind the current hd7870 to help in GPU work units. Hmm, not sure how well it would run though.
Not even sure what type of config I would have to set up to make it work correctly.

 

[t_ski]

Probably not worth it, as the Nvidia don't net as much as AMD. Red = crunch, green = fold.

My GTX470s get about 16-17k PPD each and the GTX460s each got ~8-9k. Not terrible, by any stretch of the imagination, but it would probably just confuse the HD7870 more than it did good.

If you want it put to use, my i7 folding system still has an empty slot; it could go right next to the GTX550TI

Computation Error

I'm having trouble getting BOINC to run multiple GPU WUs on my 7850. I'm getting a "Computation Error" in 2 seconds or less on each WU. All clocks are stock. The CPU runs fine. I'm using 7.0.59(x64) on an i3. Here's my app_config.xml (it's in the right place too). I need a clue.

<app_config>
<app>
<name>hcc1</name>
<max_concurrent>4</max_concurrent>
<gpu_versions>
<gpu_usage>.25</gpu_usage>
<cpu_usage>1</cpu_usage>
</gpu_versions>
</app>
</app_config>

Here's the errors

 

[t_ski]

7.0.44 is known to be stable. Try the older client. Also, what GPU drivers are you using?

 

[NastyHabits]

I'm using AMD 13.1 Drivers. How can I get Boinc 7.0.44? They only have 7.0.28 and 7.0.59 as download choices at http://boinc.berkeley.edu/download_all.php.

 

[NastyHabits]

I found it.

Nevermind. I found 7.0.44 at http://boinc.berkeley.edu/dev/forum_thread.php?id=6698&sort=5. Thanks for your help. I'm going to finish my CPU runs, clear out all BOINC software (should be easy, new PC), and install 7.0.44. Wish me luck!

You might try the 12.11 beta 4's (or 6 or whatever the last one was) or the latest betas.

12.6 runs great on all of my crunchers.... check with manofthem if you happen to be using Win8

Was there a certain required driver version for the GPU units, or what that a certain driver version for the 7770?

iirc manofthem needed to use 13.2 beta's? to keep his driver from crashing while crunching on his 7970's with Win8

I use 12.6's for all of my crunching rigs.... they do the job w/o errors and I use engineering rule #1- If It Ain't Broke Don't Fix It

Yes, first one I tried that worked was the 13.2b4. I just updated to 13.3b (due to Crysis 3), and everything has been going smoothly

Yes, same driver has been working much better on Win8. I even can watch videos again while crunching (had green playback before).

 

[hat]

Still only good for HCC? Has anyone found any way to allow a single GPU to process multiple WUs at a time while crunching for all projects?

Ah, nevermind. I see with this new method I can run every single project and still process multiple GPU WUs with a single card. Good, good...

 

[adulaamin]

Good day! My PC won't run GPU work units. I tried using the Auto-setup utility and I tried doing it manually but the BOINC Manager is showing a notice saying "app hcc1 not found in app_config.xml". I have a screenshot below of the notice and of the xml file created. The file is saved in C:\ProgramData\BOINC\projects\www.worldcommunitygrid.org and I am tried using 7.0.44 and 7.0.64.

 

[manofthem]

HCC GPU units are gone, no more, adios, so long
