Hi,

I am running a mix of projects on BOINC.

Several of them are CPU only, and several of them run on GPU as well.

It seems a waste to let Milkyway@Home run on CPU, when it runs 50x faster on GPU, if that staves Weather Simulation of CPU time (these jobs take over 300 hours, and are CPU only).

Is there a way to configure some tasks to only run on GPU, and not CPU?

As I'm a C++ programmer, I don't mind if the answer is rather complex.

The answer is rather simple
Go to your account page for the project you want to restrict and find and press the link next to "preferences for this project"
Find and press the "edit preferences" button / link (it's at the bottom)
Find and uncheck the "Use CPU" option, find and press the "update preferences" button / link (it's at the bottom)
That should do it... I think?

Yes, that's the answer.

Probably (as I don't run MilkyWay@Home) the link is this:
http://milkyway.cs.rpi.edu/milkyway/prefs.php?subset=project

I 'crafted' the link from other projects where I have account:
http://setiathome.berkeley.edu/prefs.php?subset=project
http://asteroidsathome.net/boinc/prefs.php?subset=project
http://orbit.psi.edu/oah/prefs.php?subset=project

Note:
Unchecking 'Use CPU' will disable the Download of more tasks for CPU from the particular project,
the CPU tasks already in the computer will continue to run.

Hi,

Thank you ever so much Joe Bloggs and BilBg! I've updated the preferences for all of my projects, so everything is running far more efficiently now.

I did have to use custom links, as suggested by BilBg, simply append the following string to the projects home page to allow editing of preferences for CPU usage:

prefs.php?subset=project&updated=1
