Dynamic BOINC preferences depending on what is running, possible?

Hi,
Pretty sure the answer is No, but I was wondering if it's possible to tell WCG(boinc client) to use 75% of the CPU when not doing GPU, and to lower to 50% CPU when there are GPU works running. The reason is that when GPU works is running + 75 % of the CPU, the temp rises over 90 Celsius for the CPU, and it throttle back the speed so much it's actually more efficient to use one less core(and the temp goes back to a safer 78 Celsius)

Are you on a laptop or desktop because my laptop goes between 62 Celsius and 65 Celsius but i am using a cooling fan.I just checked and now its between 59 and 60C

A Dell Desktop, but it has a crappy ventilation design. I even replaced the main casing fan with a bigger one, which helped a bit, but not enough.

Maybe useful: TThrottle

Re: Dynamic BOINC preferences depending on what is running, possible?

Create a file named app_config.xml in the WCG project folder.
Open it with a text editor and put in the following.


    <app>
         <name>opng</name>
         <gpu_versions>
                <gpu_usage>1</gpu_usage>
                 <cpu_usage>1</cpu_usage>
         </gpu_versions>
   </app>

This tells Boinc that the GPU task needs one GPU and one CPU core to run.
If you have a quad core CPU, this will take one CPU core away if a GPU task is running.
Never tested if you can set it higher than one (if there are more than four cores available).

Re: Dynamic BOINC preferences depending on what is running, possible?

BOINC only respects and recognizes integer values for enumerating how many cores to use.

0.9 for example is interpreted as 0 cores.
1.0 is interpreted as 1 core.
1.3 cores is interpreted as 1 core.
2.2 cores is interpreted as 2 cores.

Re: Dynamic BOINC preferences depending on what is running, possible?

A bit off topic to Robert Coplin.

I presume you mean the type of fan the laptop will sit on. So by how much does it reduce the temperature.
62-65 C would sound good to me.
I have an older HP and it's doing 78-80 C after I reduced CPU to 90%

Interesting. I will try both TThrottle and the app_config and see what work or not. Thanks :)
