Posted 7 Sep 2020 by Profile Nils Høimyr

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!

Post:
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.

We had an outage of some IT services at CERN yesterday, so task submission for some applications stopped for a while. Back to normal today. Hopefully SixTrack users will submit a new batch soon too.

Posted 20 Feb 2020 by Profile Nils Høimyr
Post:
We have issues with storage used for a number of CERN computing services today. The BOINC servers are not affected, but CVMFS and other layers used by the ATLAS (and CMS) application are. Hence there are no new ATLAS tasks generated now.

Hopefully things should be back to normal soon.
