Has anyone tried running these WUs with more than one CPU thread? This app_config works for me.

<!-- i9-10980XE   18c36t   4x16=64 GB   L3 Cache 24.75 MB  -->
<app_config>
<app>
    <name>10_Spacious@home[20251021.1426]</name>
    <!-- 10_Spacious@home -->
    <fraction_done_exact/>
</app>
    <app_version>
        <app_name>10_Spacious@home[20251021.1426]</app_name>
        <avg_ncpus>3</avg_ncpus>
        <cmdline>--nthreads 3</cmdline>
    </app_version>
<project_max_concurrent>12</project_max_concurrent>
<report_results_immediately/>
</app_config>

Click Read Config Files and it updates on the fly.

Apparently it doesn't actually run as multi-threaded even though BOINC will say it's using 3 or 6 CPUs. The system monitor shows that each WU is still using just a single CPU thread.
The app-version in client_state lacks the multithreaded plan class that MilkyWay has:

<plan_class>mt</plan_class>

This is from my client_state:

<app_version>
    <app_name>10_Spacious@home[20251021.1426]</app_name>
    <version_num>100</version_num>
    <platform>x86_64-pc-linux-gnu</platform>
    <avg_ncpus>1.000000</avg_ncpus>
    <flops>190267518.687804</flops>
    <api_version>8.1.0</api_version>
    <file_ref>
        <file_name>10_Spacious@home[20251021.1426]_x86_64-pc-linux-gnu</file_name>
        <main_program/>
    </file_ref>
    <file_ref>
        <file_name>10_spacious@home[20251021.1426]_x86_64-pc-linux-gnu</file_name>
        <open_name>10_spacious@home[20251021.1426]</open_name>
    </file_ref>
    <file_ref>
        <file_name>10_job_boinc[20251021.1426]_x86_64-pc-linux-gnu.xml</file_name>
        <open_name>job.xml</open_name>
    </file_ref>
</app_version>

Maybe it's not possible with their program.

I wonder how often the the App_name will change?

<app_name>10_Spacious@home[20251021.1426]</app_name>

Looks like a DATE.1421
Every time this changes our app_config files will be invalidated and require updating. I recommend using a persistent name like:

<app_name>10_Spacious@home</app_name>

And put the detailed version numbers in the WU names.

you can't just feed any app any arbitrary command line arguments to tell it to use more threads. it doesnt work like that. the app has to be built with that capability in the first place.

the --nthreads parameter is not standardized. just because it works on some apps like milkyway, doesnt mean it will work on everything. if it was available the project would distribute it as such.

Also getting a lot of WUs that fail DL and I just abort them:
