App_config.xml for running only 2 GPU tasks simultaneously ?

Is there a way, maybe by a specific app_config.xml, to set the project this way that each of my 2 GPUs crunches a task each, and no CPU tasks at all?

You can control that just

You can control that just through your standard project preference settings.  You don't need any special files.

Go to your account page on the website and find the Preferences -> Project menu item. Set 'Use CPU:' to NO.  Make sure you save any changes using the 'SAVE' link at the bottom of the page.  If you use different 'locations' make sure you make the change for the correct preference set.  This should ensure that you don't get any CPU only tasks.  You could also remove the tick marks from any CPU only searches that are listed under the 'Applications' heading further down the page.  If you don't want to crunch the already downloaded CPU tasks, just abort them after you have made and saved the change.

As far as crunching a single task on each GPU, that is what normally happens.  Your GPUs are listed as 980 Tis.  Are they both the same?  If not, you might have to use a cc_config.xml file to force BOINC to use both.  The documentation suggests that BOINC may only use the more capable device if they are different.  You can set a <use_all_gpus> option to have BOINC use both.  The documentation is fairly comprehensive concerning the available options.

 

Cheers,
