Number crunching :
How to do "GPU only" for just one of my machines?

As most people have multiple machines doing PrimeGrid work, I change my preferences periodically depending on project task WU's I want to work on collectively and for the quasi-monthly challenges for the CPU and GPU.
However, since I have one particular machine on which I dedicate PRPnet CPU tasks, I have a GPU going to waste just doing nothing. If I start Boinc, then it reads the preferences file and I get both CPU and GPU tasks. The CPU tasks interfere with PRPnet tasks. I just want this particular machine to run Boinc GPU tasks only, leaving the CPU's available for other things including PRPnet.
So, how do I configure this one machine for Boinc GPU tasks only, without affecting the preferences on my other machines?

In your preferences add another (home,work, or school)
Turn off the CPU box, leave the GPU boxes checked
that way you will only run GPU tasks

If you are willing to mess with cc_config.xml, you may try <ncpus>0</ncpus>.
cc_config is per host so it would be a way if you want to run different BOINC projects with GPU only.

Thanks, I tried that earlier today, but for whatever reason it still gets 1 CPU task. If I suspend that CPU task, it won't request any more tasks, but now I've tied up a task that someone should be working on. Here's my cc_config.xml file:
<cc_config>
<log_flags>
<mem_usage_debug>0</mem_usage_debug>
</log_flags>
<options>
<report_results_immediately>1</report_results_immediately>
<save_stats_days>7</save_stats_days>
<use_all_gpus>1</use_all_gpus>
<ncpus>0</ncpus>
</options>
</cc_config>

I'm afraid, I'll have to try this method. I dislike the terms "work, school, home". I'd rather create my own locations, but it is what it is.
Thanks.

I would use the same cc_config. If it doesn't work, I would try latest dev build of BOINC.
