I have a 12 core (24 thread) CPU and am getting 16 thread tasks, so its only running one at a time. CPU utilization is very low for a couple minutes, and then peaks around 50% for the rest of the task. Is there an app_config that would allow specifying running 2 x 12 or 3 x 8 thread tasks? It would improve efficiency greatly.

Edit I think I figured it out.

<app_config>
<app>
<name>milkyway_nbody</name>
<max_concurrent>3</max_concurrent>
</app>
<app_version>
<app_name>milkyway_nbody</app_name>
<plan_class>mt</plan_class>
<avg_ncpus>8</avg_ncpus>
</app_version>
</app_config>

I tried this on my GTX-750ti in Ubuntu 14.04 and get the following. I am running 334.21 which as far as I know is the only driver for this card in Ubuntu at this time. The card runs Einstein, DiRT and Collatz fine. But it does not run Folding@Home currently. Is this just a matter of waiting for the developers to provide work units that support Maxwell, or is there something I need to do?
