Go to one of your faulty WUs e.g

https://lhcathome.cern.ch/lhcathome/result.php?resultid=431119578

there you see that VB is blocked for boinc

Since an hour CVMFS reacts very slowly.
Can anyone confirm this?
4) Message boards : ATLAS application : ATLAS tasks not honoring CPU limitations on some PCs (Message 52492)
Posted 8 Oct 2025 by Saturn911
Post:

now all ATLAS tasks (native_mt) don't honor the boinc CPU limits (25% CPUs, 25% CPU time) and load all available cores to 100%.

I see this bug in Boinc 8.2.4 but not in Boinc 8.0.4 (Linux)

For me atlas-native is running faster then vbox and consumes less memory.
In addition, no errors for about two weeks.
I miss the theory-native. For linux, runc container was a good solution.

I wonder why it took nearly 1 day and >70 failed tasks to notice something is wrong.


What about the TRIUMF-LCG2?
They run about 90 atlas clients but no valid results for weeks.

Good to know it will do native Atlas and Vbox Theory on the Linux box.


It will not as far as I know.

On a linux box and nativ is checked:
You will get Atlas-native and vbox-cms but no theory tasks because theory-nativ has been discontinued

On a linux box and nativ is unchecked:
You will get vbox-atlas, vbox-theory and vbox-cms

Yes they are running fine but

one of yours:
3 Mar 2025, 6:50:10 UTC 3 Mar 2025, 12:35:28 UTC Fertig und Bestätigt 15,629.32 49,357.67

one of mine:
1 Mar 2025, 8:08:31 UTC 1 Mar 2025, 21:15:07 UTC Fertig und Bestätigt 47,187.62 178,800.40

Don't think this machine is much slower then yours, so what's different?

Post:
My workstations run about 16h for one CMS-task. Others do same work within 4h.
This makes me think, virtualbox takes only one cpu for work while 4cpus are loaded.

What's going wrong here?

Best way to activate your new membership is log off and log on.

Be shure boinc has started
systemctl status boinc-client


usually you don´t need the password if you are on localhost,
but for testing purposes boinc-manager allows to login with localhost and your password with

-file
-other computer

Before manipulating the *.conf files boinc-client should be stopped.

and

After a new installation of boinc start the boinc-client then stop it.
This will generate all the missing config files.
Then go to your boinc directory and edit the gui_rpc_auth.cfg.
A empty file is not an option. Give it a password.

For native tasks (native_mt or native_theory) you don´t need virtualbox nor SVM
but cvmfs must be installed.

"host modules" is the replacement for your dkms as a binary file.

Whether the "guest" files interfere you have to check yourself.

What I have described is the minimum for lhc@home
and a good way to start.

Post:
If you want to go with virtualbox on arch-linux you have to:

- remove the guest- and the dkms modules.

Then install:

- virtualbox
- host-modules for your kernel (looks like you need 6.12)

then reboot.

Be shure to uncheck "Run native if available" in project prefs!
For native you don't need virtualbox.
