Hello , i got a diffcult problem. I got three unmatching GPUs in my pc. The 3rd GPU is an 8600GT and i want it to run only for SETI GPU apps. How do i configure the cc_config.xml file in BOINC ? PLZ help ____________

There aren't any project-specific options in cc_config.xml (the "cc" stands for core client). You could configure and run two separate BOINC clients, but that's not trivial. There have been threads on that topic on the forum. Gruß, Gundolf ____________ Computer sind nicht alles im Leben.

Did you see this message in the number crunching forum? The link in there seems to explain how to run separate clients on one machine (I didn't read it myself). Gruß, Gundolf

Do you know if 8600GT can do OpenCL ?

Your only active projects that can use GPUs are SETI@home and MilkyWay@home:
http://milkyway.cs.rpi.edu/milkyway/apps.php

Rosetta@home uses only CPU:

Because you have BOINC DEV-V6.13.1 installed, you know it's a test version and maybe it don't work properly.

Maybe also interesting: 'Development BOINC 6.13.x*'.

[* currently x = 3, but will change/edited from time to time.]

I never tested it.. I guess it could work with this cc_config.xml entries:

<cc_config> <options> <use_all_gpus>1</use_all_gpus> <exclude_gpu> <url>http://setiathome.berkeley.edu</url> <device_num>0</device_num> <device_num>1</device_num> </exclude_gpu> </options> </cc_config>

-----------------------------------------
<exclude_gpu>

<exclude_gpu> <url>project_URL</url> [<device_num>N</device_num>] [<type>nvidia|ati</type>] [<app>appname</app>] </exclude_gpu>

Don't use the given GPU for the given project. If <device_num> is not specified, exclude all GPUs of the given type. <type> is required if your computer has more than one type of GPU; otherwise it can be omitted. If <app> is specified, only jobs for the given app are excluded. You may include multiple <exclude_gpu> elements. New in 6.13
-----------------------------------------

BTW.
Why you don't want calculate S@h WUs on all GPUs?
