Sightus@CAU, a member of the team Planet 3DNow! found a megaprime for base R199. The prime 1676*199^460981-1 has 1.059.731 digits digits and entered the T5k PrimePages. Continue reading...

After reporting results to primenet, all results from theses apps were invalid. We still need to investigate what's wrong. Continue reading...

Sightus@CAU, a member of the team Planet 3DNow! found a megaprime for base S905. The prime 62*905^449123+1 has 1.327.901 digits digits and entered the T5k PrimePages. Continue reading...

Dear Volunteers, we are trying to improve the distribution of SixTrack tasks. If your host could process more tasks but during the project update you don't receive any, can you let us know and send us your client logging report? Please continue the thread "SixTrack Tasks NOT being distributed"...

Warning: The WMAgent which controls CMS jobs appears to have a failed component very recently. Queue seems to be exhausted. Please set No New Tasks or change to a backup app while I try to raise someone at CERN to fix it. This could be a problem given that this is expected to be the heaviest...

We released a new version of the ATLAS app today, 2.41 for the x86_64-pc-linux-gnu platform. The new features of this version include: 1. It requires the host OS to be either Scentific Linux 6 or Cent OS 7. 2. It require CVMFS and Singularity instead of Virtualbox to run the ATLAS jobs. 3. It...

Due to the tight deadline of the ATLAS tasks, we change to deadline of ATLAS jobs from 2 weeks to 1 week. The ATLAS job takes about 3-4 CPU hours to finish on a moderate CPU (2.5GFLOPS). Continue reading...

Dear all, After testing them as the sixtracktest app, we have just pushed out executables to the sixtrack app. For the moment, we have exes only targeted for the main OSs, i.e. Windows, Linux, and the brand new one for MacOS. We are still finalising the definition of the plan classes with the...

We seem to be in the early stages of a system failure for several sub-projects. The proxy server has flatlined and my running jobs monitor is dipping alarmingly. Please check if you are getting tasks flagged as computing failures, and set No New Tasks if so. On closer inspection, it may just be...

An upgrade to the CMS@Home workflow management system (WMAgent) is planned for tomorrow (Wed Sep 27th). This needs the current batch of jobs to be stopped so that the queue is empty. I plan to do this about 0700-0800 UTC on Wednesday. To avoid "error while computing" task failures and the...

LHC@home has been consolidated and uses SSL for communication as mentioned in this thread last year. Some BOINC clients are still connecting to the old lhcathomeclassic.cern.ch/sixtrack address, that will be phased out soon. If this is the case for you, please re-attach the project to the...

We will upgrade the LHC@home web servers to the new BOINC server code with the "Bootstrap" theme on Thursday 7 December. The new style and layout can already be seen on the LHC@home development project.. During the intervention, from 09 UTC on Thursday, there may be intermittent availability of...

Due to a too aggressive spam-cleaning campaign (our fault), we have accidentally deleted some valid accounts on Monday. We have restored a backup copy of the BOINC database, and will recover the missing account data. If you get a message "missing account key" from your BOINC client, you may be...

Since Tuesday evening, we have had intermittent issues with upload failures due to a combination of a large number of new hosts running BOINC that co-incidentally joined at the same time as larger ATLAS tasks had been introduced. Our file server capacity has been increased and backlog tasks...

Our NFS storage backend got saturated and hence uploads are failing intermittently. The underlying cause is an issue with file deletion, we are trying to resolve that. Sorry for the trouble and thanks for your patience with transfers to LHC@home. Continue reading...

There will be a couple of short server outages while our BOINC service pass to fail-over nodes today, Tuesday 16th of January. Similar interruptions will happen next week, as we carry out security updates on our computing infrastructure. Continue reading...

Tomorrow Wednesday 24/1, the LHC@home servers will be unavailable for a short period while our storage backend is taken down for a system update. Today, Tuesday 23/1, some of the Condor servers that handle CMS, LHCb and Theory tasks will be down for a while. Regarding the on-going issues with...

Dear volunteers, All members of the SixTrack team would like to thank each of you for supporting our project at LHC@Home. The last weeks saw a significant increase in work load, and your constant help did not pause even during the Christmas holidays, which is something that we really...

Due to a database issue last week, task generation is delayed and we need to clean up stuck workunits. The project daemons will be on and off this morning while we try to debug a problem with the BOINC transitioner. Continue reading...

Due to a problem with the WMAgent submission task, a new batch of CMS jobs is not being put in the Condor queue. So, the queue is now draining and there will be no more jobs available in a couple of hours. Best to set your BOINC instance to No New Tasks if you can, to avoid spurious compute...
