Title: How to don't use 1 GPU in only one Project??
Post by: corsair on 22 Oct 2010, 10:32:46 am

I've one computer with two GPU one in MOBO (ATI HD 4250) and another in PCI (ATI HD 3850).

I want to use all of them in any project, except in one (Collatz)  the one from the MOBO,
as per BOINC:

#1 (0) - HD 3850
#2 (1) - HD 4250

How could be done??

I don't know of a good way of doing that...

I think this was actually brought up on the seti boards recently.  You might want to actually ask the question there.  IIRC you won't be able to run the GPU's on different projects.  If one were an Nvidia you could just set it up for nvidia and the other for ATI.  At this time I dont think they've made a CC_config line to use GPU 1 vs GPU O

From the Collatz ATI Power app readme:

Quote

Exclusion of GPUs: x  (default none)
If a certain GPU should not be used by the app, one can exclude it. The GPU number has to be in
the range 0..31. The first GPU in the system has the number 0. This option can be used multiple
times. Per default, all supported ATI GPUs are used. Do not use it with an ATI aware BOINC client!
It should be ignored in that case. But there may be some unwanted side effects.

Example:
<cmdline>x1 x2</cmdline>
The app will not use the second and the third GPU in the system.

I'm using BOINC 6.10.58 and optimized applications from the Collatz web, I've read all the Readme.txt,  and using in the
app_info.xml the factor x1, as follows:
<cmdline>x1</cmdline>

because the HD4250 is reported by BOINC as GPU 1, but nothing happens, well everything happens,
still Collatz using this GPU.
