How do I 0.25 CPU and 0.25 GPU?

The only thing the wiki how-to doesn't explain is project name.
You can probably get that from the project message boards (forums).

The only thing the wiki how-to doesn't explain is project name.

Do you have any clue about the topic of project level configuration?

The app_config.xml mechanism that was linked to doesn't have any entry for "project name".
It's not needed since such a user constructed file only needs to be placed in the correct project sub-directory.
Perhaps you meant <app_name> or just <name>? If so, those are documented so you're wrong again.

Before firing off blatantly incorrect information, maybe it would be wise to check your 'facts' first?

World Community Grid (0.25 CPU) please?

That's a difficult question to answer. I understand you want someone to write you an app_config.xml, but then that person will need to know which application(s) you run for WCG and only you know that.

Could you please elaborate and stop doing sentences of just 4 words?

World Community Grid (application)
Computer: Windows 10.
CPU: Pentium G3420 (2 Core).
tasks on World Community Grid (application):
Core 1
Task 1 (cpu0.25)
Task 2 (cpu0.25)
Task 3 (cpu0.25)
Task 4 (cpu0.25)
Core 2
Task 5 (cpu0.25)
Task 6 (cpu0.25)
Task 7 (cpu0.25)
Task 8 (cpu0.25)

Task manager:
Core 1 - usage - 99%
Core 2 - usage - 99%

World Community Grid is a conglomeration of 30 different sub-projects - although just 6 are now active. These sub-projects all have their own science applications with their own names.
To be able to write an app_config (application configuration) file, one needs to know which application it's for. That information can either be found in BOINC Manager, advanced view, Tasks tab, selecting a task and then clicking on Properties, or otherwise the information needs to be lifted from client_state.xml

The information you've given thus far is insufficient. With it no one can write an app_config.xml file for you.

This runs on the CPU only. It doesn't run on the GPU. So why would you want an app_config.xml for that?

Can it be done? App_config.xml?

Can it be done? App_config.xml?

Yes. Use the friendly name from client_state. More likely:
Mapping Cancer Markers
Probably doesn't need the 7.41 descriptor

<app_config>
<app>
    <name>Mapping Cancer Markers</name>
        <avg_ncpus>0.25</avg_ncpus>
    <max_concurrent>2</max_concurrent>
</app>
</app_config>

If the name isn't correct, the client will complain about it in the log with friendly reminder the app isn't found. No harm. Just fix it till the client is satisfied.

Use the Client/Application guideline document.

Where do I save app_config.xml to?

C:\ProgramData\BOINC\projects\www.worldcommunitygrid.org

or

C:\ProgramData\BOINC\

Where do I save app_config.xml to?

C:\ProgramData\BOINC\projects\www.worldcommunitygrid.org

or

C:\ProgramData\BOINC\

App_config.xml ALWAYS go into the project folder the file is intended for. It is a project specific file, not a BOINC file.

<app_config>
<app>
<name>mcm1</name>
<avg_ncpus>0.25</avg_ncpus>
<max_concurrent>2</max_concurrent>
</app>
</app_config>

<app_config>
<app>
<name>mcm1</name>
<avg_ncpus>0.25</avg_ncpus>
<max_concurrent>2</max_concurrent>
</app>
</app_config>

I guess. If that is the friendly name in your client_state.

Can GPU be added to World Community Grid?

<app_config>
<app>
<name>arp1</name>
<max_concurrent>2</max_concurrent>
<gpu_versions>
<gpu_usage>.333</gpu_usage>
<cpu_usage>.5</cpu_usage>
</gpu_versions>
<name>mcm1</name>
<max_concurrent>2</max_concurrent>
<gpu_versions>
<gpu_usage>.333</gpu_usage>
<cpu_usage>.5</cpu_usage>
</gpu_versions>
<name>scc1</name>
<max_concurrent>2</max_concurrent>
<gpu_versions>
<gpu_usage>.333</gpu_usage>
<cpu_usage>.5</cpu_usage>
</gpu_versions>
</app>
</app_config>

As long as they aren't GPU applications, no. As far as I know WCG doesn't have any active GPU apps at this moment.

<cc_config>

<options>
<ncpus>8</ncpus>
<use_all_gpus>1</use_all_gpus>
</options>
</cc_config>
