Just modify filenames C:\ProgramData\BOINC\projects\asteroidsathome.net_boinc\app_info.xml

on Windows, it should be (GPU tasks only):

<app_info>
 <app>
    <name>period_search</name>
 </app>
 <file_info>
  <name>Period_search_Windows_10.0_x64_cuda_v13.2_Release.exe</name>
  <executable/>
 </file_info>

<app_version>
    <app_name>period_search</app_name>
    <version_num>10217</version_num>
    <avg_ncpus>0.010000</avg_ncpus>
    <plan_class>cuda118_win10</plan_class>
    <file_ref>
        <file_name>Period_search_Windows_10.0_x64_cuda_v13.2_Release.exe</file_name>
        <main_program/>
    </file_ref>
    <coproc>
        <type>CUDA</type>
        <count>1</count>
    </coproc>
</app_version>
</app_info>

After making the changes, restart the BOINC client, and don’t forget to enable GPU tasks in your preferences. https://asteroidsathome.net/boinc/prefs.php?subset=project

Thanks, that gives me the error Missing <app_config> in app_config.xml, also event log shows no new tasks avalaible so I assume some issue with the servers sending out work there

The configuration file above is app_info.xml not app_config.xml

If your app_config.xml file is corrupted, you should either fix it or delete it. Also, check your event log for errors at startup. A broken configuration may prevent new tasks from downloading.

Ah ok I am dumb sorry, created the app_info file and now it tells me

02/04/2026 14:19:55 | Asteroids@home | [error] Process creation failed: This version of projects/asteroidsathome.net_boinc/Period_search_Windows_10.0_x64_cuda_v13.2_Release.exe is not compatible with the version of Windows you're running.

hmm, maybe some libraries are too recent and missing on your system
https://learn.microsoft.com/en-us/cpp/windows/latest-supported-vc-redist?view=msvc-170#latest-supported-redistributable-version

ok, I'll try to rebuild it with cuda 12.9 and older vc++ for better compatibility.

NVCP is showing Cuda 13.2.51 installed

@Ryan please try again with Period_search_Windows_10.0_x64_cuda_v12.9_Release.exe

Seems to be running fine so far :)

It looks like most failed but one managed to complete https://asteroidsathome.net/boinc/results.php?hostid=695215&offset=0&show_names=0&state=4&appid=

All of those failures came from the previous CUDA 13 application. More than 10 results were successfully validated, so it seems the CUDA 12 version is working just fine on your host.

btw you can also use it alongside the CPU app period_search_Windows_10222_x64_universal_Release.exe which has some new AVX/FMA/AVX512 optimizations, so it should be slightly (~10%) more efficient than the current CPU app.

Ah ok, must have been delayed in reporting.
Do I need to add the CPU app in manually to that file now that I am using ther custom GPU one? , and iff so is it the same text but with the app .exe changed?
Boinc was reporting no CPU apps avalaible when I used it.

You need to specify both the CPU and GPU versions of the app
https://asteroidsathome.net/boinc/forum_thread.php?id=1157&postid=9300#9300

and replace all file references, since you're on Windows
ps_linux_10222_x64_universal_Release -> period_search_Windows_10222_x64_universal_Release.exe
ps_linux_cuda13100_v10222_Release -> Period_search_Windows_10.0_x64_cuda_v12.9_Release.exe
plan_class cuda118_linux -> cuda118_windows

Just be aware that if you're using custom apps via app_info.xml on any project and a new version is released, the app won’t update automatically.

Got it, thanks and it looks like its now working on CPU and GPU, will report back :)
Many thanks for helping!
