I have seen similar behaviour with a different MultiCore-Project (MIlkyway) and BOINC-Client 8.2.5

If there is a local app_config.xml, the client uses the configured settings from this. If there is no app_config.xml, the client ignores what on the project-preferences is configured and uses the last config it remembers, regardless of the setting on the project-preferences

Seems to be a bug in client since 8.2.4 and higher

Cheers I think that clears it up :)

This is the recommended CVMFS starting point:
https://lhcathome.cern.ch/lhcathome/forum_thread.php?id=5594

This option shouldn't be used (remove it, except if you know exactly why you need it):
CVMFS_CLIENT_PROFILE=single

This is recommended (as a private volunteer you should understand it as a MUST):
CVMFS_HTTP_PROXY="auto;DIRECT"
CVMFS_USE_CDN=yes



As for CVMFS_USE_CDN/Cloudflare/openhtc.io

https://openhtc.io/
openhtc.io is hosted by Cloudflare.
You don't need a Cloudflare account to use it.
openhtc.io distributes CVMFS/Frontier content required by ATLAS/CMS/Theory via a worldwide proxy network (hundreds of Squid proxies).
If you don't use the CDN CVMFS/Frontier get their data via "stratum-one-servers" (only few worldwide).
Getting the data from a CDN proxy close to your location instead of getting it from a stratum-one located far away is usually faster.

Thanks all! I thought we have local problems and not picking up jobs ... they are coming now.

Hello,

I downloaded the script theory-vbox.sh from link https://github.com/seanr22a/LHC-Theory/blob/main/theory-vbox.sh
Then I tried to run it with the following Terminal command:

sh theory-vbox.sh
And I got the following result:

-e

Some kind advice would be very appreciated

... What is it about this project's crunching that produces such wildly varying runtimes?...
It's a result of the scientific input which you get (by random) from the backend queues.

je pense que mon ssd est hs car j'ai 2 secteurs réallouer.

I think that my ssd is down because I have 2 sectors reallocated.

The graphs are looking normal again. Thank you!

As mentioned in this thread, we finally have the new Xtrack BOINC application available for beta testing.

Please refer to the Sixtrack/Xtrack forum for further details and feedback discussion. Tasks should hopefully be available by tomorrow.

merci pour la réponse rapide mais je vais tester si theory virtualbox fonctionne.
Je vous tiens au courant.

thank you for the quick response but I will test if theory virtualbox works.
I’ll keep you informed.
