Guide to running multiple GPU work units

At the very least, the GTX460SEs will use far, far less power than the GTX295s. I'd imagine the two GTX460SEs would probably get 12k PPD together--not bad. You could certainly slip in another card--what do you have?

I was thinking one of the GTX 295's if it came to that configuration. What kind of performance does a 295 give?

To be honest, I'm not sure. I don't know of anyone on the Team who is running the older GTX2xx cards.

I have two GTX 560 Ti's in the gamer I could swap around...I don't see that much difference between those and the 460's for gaming, but I understand the 560 Ti is much better at this game. I do hate the 295's sitting here not doing a thing tho. I suppose I could just set them up and try it to see what gives.

[rickss69]

Ok - I have the two GTX 295's running now with four gpu's loaded around 95% each...I guess they will only pull one at a time. When I first began only the cpu was getting work, but now the gpu's have taken over. How do I determine what the ppd is for each gpu? Each one is polishing one off at 15 minute intervals.

A WU every fifteen minutes means about 4 points/minute per GPU core--or about 16 points/minute total with the two GTX295s. Or ~22k PPD--better than I would have thought

Now, should I leave it as is or try the GTX 460 SE's for effect? Maybe I should Fold with the cpu at the same time since the gpu's have taken over? When will my badge re-appear? So many questions lol...

Not sure about the badge TBH.

If you're running both of the GTX295s, that's higher output than I got from a pair of GTX460s, so you might as well stay with that. Unless power usage is a concern, and the two-GPU solution would be better.

[Chicken Patty]

Alright guys, how do I verify if this is working correctly? I used the auto utility and put the XML file in the folder where it goes. I put it to run 2 WU's on my 6850 for now. This is what my tasks look like at the moment, just started BOINC up. I also installed the latest version.

[[Ion]]

It's not working--if it was, it would say that it was running two WUs, each using .5 AMD GPU(s).
Can you paste the Event Log here and the contents of your cc_config.xml file?

Thanks!

Sorry, I asked for the wrong file--I mean to ask for app_config.xml (in the ProgramData\projectw\www.worldcommunitygrid.org\ folder). You may also wish to make sure that the file doesn't have the .txt extension.

Don't think it does, here is what it looks like in the folder:


and the contents of the file:
- <app_config>
- <app>
<name>hcc1</name>
<max_concurrent>2</max_concurrent>
- <gpu_versions>
<gpu_usage>.500</gpu_usage>
<cpu_usage>1.000</cpu_usage>
</gpu_versions>
</app>
</app_config>

app_config.xml must go inside the www.worldcommunitygrid.org folder inside of the Projects folder shown there

Done deal, now we are cooking.

[brandonwh64]

You may be better off just doing 4WU on the 7770 and none on the CPU

If it doesn't grab 2 gpu wu's right away don't worry too much about it. If it doesn't you can try:

- wait until one of the cpu jobs is done
- abort a cpu job
- restart the BOINC manager or restart the PC

Check the event log when BOINC starts- if it sees the file it will acknowledge it in the log and you're pretty much good to go from there

EDIT- nvm you're all set

Well, that's a HD6870, and the CPU is an i7-2600k, so I'm not sure I follow your logic...

[Chicken Patty]

Well the 7770 I'm setting up now and that's paired to a i7-950.

I thought this was for his 7770..... My bad

I just set up the 7770 to run four WU's. Loading it up about 95%. Going to give that a shot and see how it goes.

My suggestion for that would be five GPU WUs spread across three threads, with the rest of the CPU doing standard tasks

Seems like other people have better suggestions. Good luck with the WU's

How would I set that up with the Utility? Would I put it to run 5 WU's per card, but how many threads so I specify the PC has? I still say eight or...?

With the utility you have to put 10 WU at a time, 5 per card and 6 threads.
