Guide to running multiple GPU work units

[oldDirty]

So are we going to see 100K per day (10 GPU units at the time)? You got an better CPU then me and I can do 95K in average.

I managed to duplicate t_ski yesterday by running the most productive host. I think that all of the 3x7970 rigs had an off day but still my little workshop open box rig did come out on top.

Edit: Bangkok Crunching Team, well it all goes in the same pot.

But my CPU has only 4 threads, or it dosn't matter?

It's ok when other like to join, but it's not that important.

You can run 10 on 4 threads but maybe 8 would be better. Now that you do have a newer version of BOINC you should go to post 617 and download that little program and ask for 8 GPU tasks.

impressive...it works omg...
It it also possible on Cypress GPU > 5850? maybe i buy one for my old Dell Dimension. It only had a 9500Gt that crunches a bit for Einstein.

FWIF: I'm currently running 0.4 CPUs + 0.1 GPUs (20 WUs on 8 threads) so 10 WUs on 4 cores should do ok.

Obviously a little experimentation is needed

Yup running the same configuration. Seems that if your clocks are around 4GHz you can at least get the desired 100K out of each.

Hey Kiex, good to hear from you
Maybe you could throw in the OP that multi WUs on Win8 works with the 13.2beta drivers (13.2b4 tests for sure); 13.1 didn't work. Just a thought ...

Had a few minutes to use internet today so had to come back to my second home Likewise good see things are all well here.

Made the update to the pre-requisite / driver section. That's good news because I had to swith my rig back to 7. Wish AMD were a little quicker with their drivers..

Glad to hear that you're well, though it sounds like you're busy!

I have to say that I was stoked the other night when I tried it out and found it to work; I posted in the other thread about it here. After that, I came back to 7 to finish up the other downloaded work, and it literally just finished. I'm about to switch back to 8 and enjoy it

I know you're busy but try not to be a stranger here

Definitely busy. Getting fit, trying to get driving license, travelling to remote places and generally making the most of a short break away from the daily hussle of work. Probably need to go back to UK in April to look for a job again.. but till then enjoy life.

Hopefully I can get back and sort out the unreliable SR-2, spare GPU and all the RMA's for the dead hardware from the H100 failure.. before the GPU WU's end.

I've bin away from Corsair products since 2 Years and it was a good decision.
The Quality managment is not the same like few years ago, it seems they slaughter their name.
Look for the NZXT Kraken review and get surprized.

Been throwing a bit extra into the pot over the last few days with my main box. However, with the new boinc client, I find I can no longer use my 260 with my 480. I'm using the newest version of the config util, tell it 4 wus total, 2 per card, and I can only get 2 wus running on my 480. Any ideas? It did work before with the older boinc client.

I can't seem to get the multi GPU WU to work. It only runs 1 WU with GPU at a time. Anyone can help me with my app_config.xml file configuration? Here is my rig details:-

i5 2500k @ 4.5Ghz
Sapphire 7970 w/ Arctic Accelero Xtreme 7970
ASUS P8Z68-V/GEN3
BOINC ver 7.0.40(x64)

Current app_config.xml.
<app_config>
<app>
<name>hcc1</name>
<max_concurrent>4</max_concurrent>
<gpu_versions>
<gpu_usage>.500</gpu_usage>
<cpu_usage>1.000</cpu_usage>
</gpu_versions>
</app>
</app_config>

Thanks in advance

I ran into stuff like that before. I ended up uninstalling BOINC, deleting the ProgramData folder, reinstall and download the files again, and then sometimes you just need to give it a few minutes to update.

Is it running 1WU on both gpus?

Sorry, I think my post misleads you. It is only 1 GPU. Sapphire 7970 with the custom cooler. However, only 1 WU is using (1 CPUs + 0.25 GPUs). The other 3 WUs are using CPU (I assume)

 

[Bow]

I am at work so can't do anything until I get home.

So if I understand this right all need to do is update BOINC, then shut it down, then run the easy set up program and fire it back up. Log into my BOINC then tick accept gpu work. Right? Or did I miss something?
see pc specs, the gup's are stock HD 6950's 2 gigs each.
can I run in xfire?
What kind of temps are ppl getting on there gpu's?
I also game on this rig, if I want to play can I just turn off the GPU work and then back on when finished?

I will set them up tonight after work,

Thanks for any help.

You are asking for 4 units in total and 2 off them should be GPU units and each of them can use 1 CPU thread. That should net you 2 GPU and 2 CPU units.

Did you use the program in post 617??

Technically the program doesn't works as I tried to run it because my BOINC isn't on the default folder. So I manually created the xml file and paste to the directory. On my BOINC, I did run "Read config file"

You're right that's all you have to do.
Yes you can crossfire (just verify that it does not send errors).
My HD 7870 is running at 41C with 8 wus wich is just a little bit more than on idle... My HD 5770 is running at about 46C with 2 wus.

I'll find a solution for that... hopefully tonight!

 

[ThE_MaD_ShOt]

just as m&m's said, you can try crossfiring just pay very close attention to the rig for a couple weeks for errors. Also if you start getting driver crashes and stuff don't be alarmed. Just disable crossfire in Amd vision control while crunching.

How many Wu's should I run?

 

[[Ion]]

How many Wu's should I run?

I'd say run three WUs/GPU and give each one 2/3 of a CPU core--then leaving two cores free for CPU tasks too. You could also play with 4 WUs/GPU, but I'm not sure that it would work better.

 

[ThE_MaD_ShOt]

How many Wu's should I run?

On my crossfired 6850's I do 1 wu each and 4 cpu units. I can probably crank it up to 2 or 3 wu's per card. Now on my 7850 single gpu rig I am running 4 wu's and no cpu units.

 

[m&m's]

I'll find a solution for that... hopefully tonight!

3 hours later... Version 1.2.0 is UP!! You'll find it on post #617.

 

[ArticFir3]

I downloaded the program and paste the xml file to the folder. Problem is I always get 4 WUs running, 3 core and 1 GPU. Any idea how to improve the crunching?

Post a copy of the text from the xml file you used and we'll have a look...
