Dear All,

Due to the techinical reasons the page with jobs statistics are now available at:

Once the reasons will be solved (in a ~week) the page will be again available at old address:

3) Message boards : Theory Application : Theory Failure Ratio Explodes (Message 48575)
Posted 19 Sep 2023 by Anton
There was an update to the new version of scientific software yesterday.
The update has issues and this is the reason of failures. I am looking now for the solution and will update once it is fixed.
Thank you for the notice!

Hi All,
Indeed the madgraph code default is to use all CPU cores.
This is corrected and the limit now is set to 2 cores max.
(It will take a few days until new jobs will arrive.)

Hi Crystal,
This is an error in Rivet package which we use for analysis and histogramming, I have notified authors. It will be fixed in the some of the next version and the error will disappear.
Thanks for the pointer!

Hi Christoph,
The detailed job log indicate the job failure is due to a network connectivity problem - the machine is not able to download some of files from CVMFS network file system for job execution. I am not sure what is the core reason for this, but it also could be weak network connection or firewall configuration.

Dear Friends,

An updated* mcplots codes is subscribed for the BOINC production now.

This time the update addressed Sherpa event generator and particularly issues with the endless loops which should be significantly reduced or disappear now.

Happy crunching!

Hi Crystal,
The new revision is subscribed for production with the problem fixed.
Thanks for the notice!

Posted 9 Jan 2020 by Anton
Ooops, one more environment setup problem which breaks visualisation, which leads to job stop.
Jobs queue with old jobs are cleared now, and new jobs will start without visualisation as a quick fix.
Let's see how this will work and next days I will do a proper fix to re-enable the visualisation.

Posted 8 Jan 2020 by Anton
Today the new configuration without 32 bits support is subscribed for the production at BOINC.
The 32 bits version of LHC@Home Theory application will be removed soon.

Enjoy the progress of new configuration (revision 2362) at:

Thank you for your 32 bits contributions, and Happy New 64 bits Year!

Posted 23 Nov 2019 by Anton
Dear Friends,

The MCPlots project is currently completing an upgrade of its event generator codes and we plan to introduce this revised code into mcplots tasks for BOINC production very soon. From this point on, it will unfortunately not be possible to support 32bit environments and we plan to remove the 32bit option from the Theory application.

To remind you, 32bit platforms are not officially supported by CERN for new installations of HEP codes since a few years already. So it has been more and more difficult to keep Theory compatible for 32bits even in "degraded" mode using only old versions of event generators. Currently the 32bit application contributes only 1-2% of total Theory computing power - see https://lhcathome.cern.ch/lhcathome/apps.php - so the phaseout will be practically invisible.

Nevertheless this marks a milestone for the Theory project, and it’s time to thank again our early volunteers who have continued to support us with 32bit systems during the general move to 64bits.

We recommend anyone who still runs on 32 bit systems to switch to Sixtrack which will support these for a while longer.
