As far as I can see, this is not on the project side. On our servers the DB-dump jobs are running and the contents of the html/stats directories of the 2 projects different. (Orders of magnitude more hosts and users for LHC@home than our dev project.)

The LHC@home team wishes you all a Happy New Year and all the best for 2022!

The simulations carried out under LHC@home contribute to improvements to the LHC accelerator as well as the experiments. The upcoming Run 3 of the LHC shall start soon.

Meanwhile you can take a look at this video with highlights from CERN during 2021.

Many thanks for your contributions and happy crunching!

The database underlying LHC@home will be down on Saturday 27th of June due to an upgrade of a DB storage rack.

Hence LHC@home BOINC services will be unavailable for a good part of the day. (Est 5:30-12:30 UTC)

So your BOINC client connections to our servers are likely to fail on Saturday.

Thanks and happy crunching!

This should be fixed now, also for wget and older BOINC clients.

This expiration took many of us by surprise:

Like many organisations, CERN is also affected by the COVID-19 pandemic. Researchers in the CERN community are trying to help out in different ways, as explained on this web page.

As part of this effort to fight COVID-19, we also contribute computing power to Folding@home and Rosetta@home from temporarily available servers that were about to be decommissioned.

During periods like this with little work from LHC@home, we also encourage you to participate in other BOINC projects such as Rosetta@home and contribute to the global fight of the pandemic.

Many thanks for your contributions to LHC@home and continued happy crunching!

With the best of wishes of good health for your and your families from the LHC@home team.
