Ive got an 8800 GTX OC and an 8600 GT 768 and 512 meg ram respectivly on a AM2 6000+ System. I am running one job on each CPU core, but BOINC is only utilizing one of My GPU cores on the 8600 GT. How do i get it to utilize my other 3 dormant Cores

---

GPU cores run in parallel, so one WU per GPU is correct.

according to rivatuner ony one GPU core on the 8600GT is being used, the ither is Idle, the 8800GTX is not being used at all. BOINC only shows 1 CUDA work unit being proccessed

A Core on a GPU is different to a Core on a CPU. Only 1 Work unit will be processed per video card unless the video card has 2 GPUs on it.

Wild guess- try the latest stable NVidia drivers.
The BOINC log only shows 2 video cards- both of them 8600GTs with 256MB of RAM. So ne of the cards maybe a phontom, and the 2 other cards aren't being detected at all.

These cards are single GPU cards, so they will only run one task per GPU.

Due to a permission limitation in the driver detection API used by BOINC which was made by Nvidia, it happens that the first (or second) GPU isn't used by default on some versions of Windows.

This can be overridden by making a cc_config.xml file in your BOINC Data directory (7/31/2009 1:50:16 PM Data directory: C:\ProgramData\BOINC), with in it these lines:

<cc_config>
<options>
<use_all_gpus>1</use_all_gpus>
</options.
</cc_config>

It's best to use Notepad to make cc_config.xml and save it as an All Types file, so it doesn't get an extra .txt extension. So do check the file after saving it. When it is called cc_config.xml.txt change its name and take the .txt part off.

Exit BOINC and then restart it.

found that thread and did that.. to no avail. interesting thing, i disabled the 8600 and now...

so with both cards enabled it shows them both as a 8600GT with the 8600GT disabled it only shows the 8800 GTX.. also runnign latest driver pack from nvidia as well as the 2.3 cuda drivers. i have put the cc_ file in both the programdata/boinc and the seti dir specificaly.... is there somethign else i need to do to force a read of that file?

---

just a postulation, could boinc have a problem running the gpu's from two different companies? one is from BFG the other is a XFS i do believe?

---

I think this is a feature of BOINC when using disimilar GPUs. I briefly tried running 2 different GPUs in one machine and found the same thing but never got to the bottom of it. Misreported card details but they both ran OK.

See message 910085

If you go to Nvidia web sight they will tell you that for a SLI configuration the cards have to be of the same type such as two 8600s or 2 8800s. You are not to mix the cards or they become unstable.

Just because you have two cards doesn't mean you are using SLI.

Aye Joseph, the second gard is a deciated Physix Card when i am gaming, and a second monitor when not.

---

But you got them both to proccess units?? because even with the misreport, its still refusing to use the 2nd card.

Did you disable SLI?
Are you using the cc_config.xml entry as proposed by Ageless?

Gruß,
Gundolf

not using SLI, and have teh cc_file in.

---

Oh fun.

As is said elsewhere, there is a typo in my cc_config.xml example. here's the correct one:

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

all tried. no longer running adaul monitor setup so i will just live with as is for the time being. thank all for their idea's.

you also need to be sure you have a "number_of_gpus" filename with no extension containing a 2 on the first line as the first character in the seti project directory.

if you use the 8600 for your desktop as well chances are it will not be used due to memory limitations. cuda requires unhindered full 256mb ram absolute minimum., i had an 8600 in such a scenario and no matter how small i made my desktop 'ramprint' cuda would not use it until i used the other card for my desktop which had more ram (most active desktops use more than 256mb vidram. mine uses around 384mb in minimal configuration and almost 512 in 'working' config).

the report that boinc gives in the messages log is broken and has been for a long time. as long as you see the seti 6.08 application running the proper devices that is all that matters. i have only seen one version of boinc that reported the devices properly but it was broken to be able to use both devices. its just cosmetics and does not affect how boinc uses the gpus at all.
