I want one of my boxes to crunch only CUDA WUs.
This box is attached to GPUGRID, Seti and SetiBeta.

GPUGRID is OK. It has only CUDA WU.
Seti and SetiBeta: I marked (in primary, home and work preferencies) :
- Seti@Home Enhanced : yes
- Astropulse : no
- Astropulse V5 : no
- No work from other application
- use GPU if available : yes
- Use CPU : no

But I continue to recieve Seti not CUDA WUs.
Is it correct ?? Is it possible to recieve only CUDA WUs.
Is this a Boinc problem, or a Seti problem ??
Or is ...... my problem ???
This box is AMD 5200+ with WIn XP 64b
BM 64b 6.3.38
I searched in the forum, but I haven't seen anything dealing this situation

Can you select at SETI in the device profiles/host venues what work can be sent to your client?

edit: seems so

What applications do you use?

If you use the standard project-supplied applications, then the website prefences you've listed should work.

If you use third party or optimised applications (as many at SETI do), then I think the web preferences get overtaken by the app_info.xml specified apps. If you don't want to use the CPU, don't soecify a CPU application in app_info.xml

I use only standard application - No more app_info.xml

May be this is a Boinc problem.
In the same box there is alo Aqua, and also this project has the same behaviour:
I setted only GPU work (the same way as Seti@home) but I have this message (request for a CPU work)

22/07/2009 15:59:36 AQUA@home Sending scheduler request: To fetch work.
22/07/2009 15:59:36 AQUA@home Requesting new tasks for CPU
22/07/2009 15:59:41 AQUA@home Scheduler request completed: got 0 new tasks
22/07/2009 15:59:41 AQUA@home Message from server: (Project has no jobs available)

One of these things to try, since GPU crunching requires a little CPU use. Edit the global_prefs_override.xml and set <cpu_usage_limit>0.000000</cpu_usage_limit> then reread the file via the advanced menu.

Through the interface entered you get the above, but the prefs screen still shows 100.00 %.

The GPU function can be disabled in BOINC, but not aware this can be flat done for the CPU part. For a 4 core try anything below 25% of processors. I don't do GPU crunching, but 24% sure set off a benchmarking and stopped all CPU computing... everything sitting there 'waiting to run'. Theoretically you then have told the scheduler not to fetch anything for CPU, whilst I understand that CPU and GPU have separate schedulers.

The prefs screen is setted 15% (in a previous attempt to reduce the CPU usage). Now I setted also <cpu_usage_limit>0.000000</cpu_usage_limit>.

I'll wait till the actual Seti CPU WUs will finish
