On windows task manager I find that GPU's computing has been suspended at per 25% rate of progress. My computer GPUs are HD7990. It can finish a task within 48S, but it takes almost a 10S rest every 48S. I think that project preferences can be added GPU utilization factor like einstein@home. users can be allowed to change it as a user preference.

You can change it yourself in app_config under gpu_versions.

Thank you for your reply. But Where can I find that? Is it a .xml file under the C:\ProgramData\BOINC folder? I can't find any files with names you said under the C:\ProgramData\BOINC folder, C:\Program Files\BOINC folder and their subfolder.

<app_config>
 <app>
  <name>milkyway</name>
  <gpu_versions>
   <gpu_usage>0.5</gpu_usage>
   <cpu_usage>0.25</cpu_usage>
  </gpu_versions>
 </app>
</app_config>

Save this as app_config.xml in Milkyway's project folder (use plain text editor like Notepad) and it will run 2 WUs per GPU. With <gpu_usage>0.33</gpu_usage> you can even run 3 WUs per GPU, but you'll have to check yourself, if that's better than two or not. Btw, don't need to care about the cpu_usage value as long as you don't run CPU tasks, this is just what I have in my app_config.

EDIT: This file does not exist if you didn't create it yet by yourself and should be placed in C:\ProgramData\BOINC\projects\milkyway.cs.rpi.edu_milkyway

It works, thank you
