Guide to running multiple GPU work units

It's working, and its amazing lol...
thanks for your help man!

With 4WU's on the GPU each 20% max load, MSI AB reports 95% GPU constant usage.
The most amazing part is that the "Help Conquer Cancer 7.05" takes 4 and a half minutes to finish with 4 of those running at same time.!!!

Awesome!!! :rockout:

Glad it worked out for you! :)
 
Once I run the auto set up and hit enter is that it? I updated, ran the setp. I set it up to run 1 per card. Now I have lots of tasks ready to report and my running tasks are blinking?
whats up with that?

Not sure? Did you do a manual update to get the ready to report units reported?

Also, after you ran the utility did you restart BOINC and/or reboot?
 
yes to both, and ready to report tasks were sent, but the running ones are still flashing a little, not sure just keep an eye on it.
 
my pc become very laggy while gpu wu running
i cant watch video (1fps)
can anyone advice me for app_config

<app_config>
<app>
<name>hcc1</name>
<max_concurrent>4</max_concurrent>
<gpu_versions>
<gpu_usage>0.5</gpu_usage>
<cpu_usage>1</cpu_usage>
</gpu_versions>
</app>
</app_config>

setup spec in my System Specs

Unfortunately, particularly for nVidia GPUs, this is just a fact of life. So I'd suggest you set it to run the GPU app only when the computer isn't in use.

Yep, this is about your only option with Nvidia and crunching.
 
is there have any way to run video player on IGP (like nvidia optimus)

or lucid virtu mvp possible to solve this?
 
If you had two video cards you can crunch on one of them and use the second for the system & display (I think), but I'm not familiar with doing something like this. However, I know you have to tell BOINC to use more than one card, so it should default to one card if you don't. I guess the trick is telling it the correct card to crunch on so the system can use the other.

I did this when I still had a GTX460--I'd put the GTX460 in the first slot and an 8400GS in the second slot. Then I just told BOINC to only use one GPU (in the cc_config.xml file) and it only ran tasks on the GTX460. I then drove the display with the 8400GS, and it was perfectly snappy for everyday use.
 
Just a quick question, I just tried to run 3 WU's on my 680, it ran one task that I already had downloaded fine, but now I cannot get any more task's. Whenever I press the update button, I get this error in the event log, "Server error: feeder not running"

WCG is in a brief shutdown for maintenance- give it a few more hours and try again...

Oh ok, That's what I thought, though usually there is a message in the event log about that.
 
Is there any way to only allow it to use 50% of my GPU? I've set it to only do 2 work units and 0.25, but My GPU still runs at full load.

My understanding is no--the GPU doesn't have the ability to be fine-grain controlled like CPUs do :ohwell:
 
my pc have two (gtx 680 (device 0), gtx 580 (device 1)) gpus
how to configure hcc1 run only device 1 (gtx 580) while i use PC

From what I understand, BOINC isn't able to suspend GPU's individually based on different parameters. Either both are running or both are suspended.

If you want to have just the 580 crunching to free up the 680 for other things, you can edit the cc_config file to include this:

Code:
<exclude_gpu>
   <url>http://www.worldcommunitygrid.org/</url>
   <device_num>1</device_num>
   <type>NVIDIA</type>
   <app>HCC1</app>
</exclude_gpu>

Didn't get a chance to test that code, but if you want to read up more you can try this page with all configuration options explained: http://boinc.berkeley.edu/wiki/Client_configuration
 
thanks, now it's working

i tried this before, but i was wrote url wrong (project_www.worldcommunitygrid.org or www.worldcommunitygrid.org)
i changed HCC1 to hcc1 (boinc shows error)
since it's exclude i need to exclude my primary gpu it's GTX 680 (device 0)

now everything works what i want
s@h and gpugrid for device 0 (GTX 680)
hcc for device 1 (GTX 580)

and i enabled Use GPU always (instead of Use GPU based on preferences)

Glad that's sorted :)
 
Trying to get my GT430 to work. It's NOT on the unsupported GPU list: https://secure.worldcommunitygrid.org/help/viewTopic.do?shortName=GPU#610

but I can't make it work with boinc. GPU-Z reports 0Mhz as current speed, DC, Physx and OpenCL are uncheck. Used 310.9 drivers.



edit: seems to be a problem on my end. Device manager shows an exclamation point. *sigh* let's dive in...............

Here's a list of supported gpu's (GT 430 is near the bottom of the list)
http://www.worldcommunitygrid.org/forums/wcg/viewpostinthread?post=396388

I did a quick search on the WCG forum and found a few posts for the GT 430 using "430" as the search term. I didn't find anything helpful yet but you can always try there :o
 
What would be the optimal number of WUs for a 6570? 2? 1?

480 shaders, 650 Mhz.

I see no point to run 2 WU on 6570.
My HD6570 (670 MHz) completes 1 WU in ~15 min.
HD6670 (900 MHz) -:- ~12 min.
 
I'd agree, that's a slow enough card that two WUs will probably just be a waste of CPU power :ohwell:
 
Going by this guide it appears that it would be better to run two GTX 460 SE's over two GTX 295's...is that correct? Would it be possible or beneficial to slip another card in with them?
