I looked at my schedules tasks and they all show 0.91CPU along with the GPU. What does 0.91CPU mean? I have eight cores available.

Thanks.

I'm assuming that's the value reported by the manager and it's for a GPU task? The .91CPU would be how much of a CPU it's using in addition to the GPU. The .91 seems kind of high. You can lower it by setting the cpu_usage in the app_config.xml file. I have mine set to .2. As it runs watch how much of the cpu it uses and use that to get a better value for your system.

create an xml file called app_config.xml inside of the project folder
(C:\ProgramData\BOINC\projects\numberfields.asu.edu_NumberFields)

I use the following where I run two tasks at once on my GPU

<app_config>
<app>
<name>GetDecics</name>
<max_concurrent>4</max_concurrent>
<gpu_versions>
<gpu_usage>.5</gpu_usage>
<cpu_usage>.25</cpu_usage>
</gpu_versions>
</app>
</app_config>

You will have to do this for each project
This is just an example and depending on how powerful or the type of GPU you can do multiple tasks at once
gpu_usage
1 = 1 task
.5 = 2 tasks
.25 = 4 tasks

You can get more information here
