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?

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.

Any password will do the job
and
your account must be a member of the group of boinc.

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.

How is this possible running 4 core CMS tasks hundreds of times?


I was just looking around to see how they are running here.

1100 credits for 2minutes of cpu.
One of the best invests I'v ever seen.
And this without scientific benefits.
A typical "thanks for nothing".
Or just waste of time...
