Yet the project PrimeGrid I think they have found a way to choose between the application in cuda, ati or cpu in our preferences on their site?!

Hello,

This issue due to be installed already, why not put an option in the preferences to select sub-projects in CPU version? This avoids the need to make a file or abandon app_info CPU units that we do not want to ....!

thank you to the admins for your answers ....

Sincerely,

BOINC controls the number of threads used. If you want to set the number, you use something like <avg_ncpus> and <max_ncpus> in app_info.xml. You also might be able to control it more directly with the command line control that I think exists in app_info.xml by adding something like <cmdline>--nthreads 4</cmdline>, though I'm not sure how that will play with how BOINC wants to schedule things.


<avg_ncpus> and <max_ncpus> only TELL boinc how many CPUs a sci app uses; it does NOT dictate to the sci app. I tried param --nthreads=4 and set the ncpus params both to 4. Hard-coding the number of threads seems to work. Thanks for the tip.

ok

Is it not possible to have an option to choose between the CPU application nbody milkyway and 0.50, if we do not want to do one or the other?

ex : if I want to just 0.50 in nbodys and GPU or 0.50 CPU et 0.50 GPU...
