So it is possible to run both GPU and CPU through app_info.xml and that way limit gpu usage. For some reason when I tried it last time it gave just errors or didn't run on both.

Here is my App_info.xml file.

<app_info>

  <app>
    <name>milkyway</name>
  </app>

  <file_info>
    <name>astronomy_0.20_x64_SSE3.exe</name>
     <executable/>
  </file_info>

  <app_version>
    <app_name>milkyway</app_name>
    <version_num>19</version_num>
      <file_ref>
      <file_name>astronomy_0.20_x64_SSE3.exe</file_name>
      <main_program/>
      </file_ref>
  </app_version>

  <app>
    <name>milkyway</name>
  </app>

  <file_info>
    <name>milkyway_0.21_windows_x86_64__ati13ati.exe</name>
    <executable/>
  </file_info>

  <file_info>
    <name>brook64_ati.dll</name>
  </file_info>

  <app_version>
    <app_name>milkyway</app_name>
    <version_num>21</version_num>
    <flops>1.0e11</flops>
    <avg_ncpus>0.05</avg_ncpus>
    <max_ncpus>1</max_ncpus>
    <coproc>
      <type>ATI</type>
      <count>1</count>
    </coproc>
    <cmdline></cmdline>

    <file_ref>
      <file_name>milkyway_0.21_windows_x86_64__ati13ati.exe</file_name>
      <main_program/>
    </file_ref>

    <file_ref>
      <file_name>brook64_ati.dll</file_name>
    </file_ref>
  </app_version>

</app_info>


The first file_info and app_version is for optimized cpu application to change the cpu application, just rename both "astronomy_0.20_x64_SSE3.exe" parts to corresponding exes.

The second and third file_info and second app_version is for the ati GPU application. And here you can find the <cmdline></cmdline> where you could put the normal options.

What if you Travis add there an feature where the application would read a file where a user could put the options as on app_info.xml <cmdline></cmdline>?

I'm using boinc 6.10.29 this release has a "snooze GPU" feature. It might be worth trying. Right click on tray icon, its in the menu there.

I have 6.10.29 and I know I can pause GPU work, but can I limit the GPU workload through app_info.xml and still have the ability to use both CPU and GPU and pause GPU work while CPU continues to calculate?

So can I somehow get it to work so that BOINC would run both CPU and GPU work and I would have the ability to pause GPU work? From few people posts I got the impression that app_info would make the applications as anonymous platforms and BOINC would deal them as CPU applications hence I would have to pause both CPU and GPU work if I would only want to pause GPU work.

The main question is, can I get both of them to run through app_info.xml?

I would like to ask is there any option on which I could limit the usage of the milkyway GPU application.

I know that the "optimized" GPU program had the ability to set different wait factors and kernel frequency through app_info.xml but there isn't one on default milkyway.
