From what I can see the task is still running
3) Message boards : CMS Application : CMS@Home difficulties in attempts to prepare for multi-core jobs (Message 49976) Posted 8 days ago by Erich56 Post: no jobs for several hours, but the automatic stop of tasks distribution does not seem to work :-( Thus causing thousands of useless tasks being uploaded after about half an hour runtime without results for the science :-(

5) Message boards : CMS Application : CMS@Home difficulties in attempts to prepare for multi-core jobs (Message 49841) Posted 25 Mar 2024 by Erich56 Post: thanks, computezrmle, for your thorough explanation :-) When you say "I expect the singlecore CMS on prod will be replaced by a multicore app" I hope this will mean the same as for ATLAS, i.e. we volunteers can choose between 1 and n cores per task.
6) Message boards : CMS Application : CMS@Home difficulties in attempts to prepare for multi-core jobs (Message 49836) Posted 25 Mar 2024 by Erich56 Post: what's going wrong? The multi core CMS is tested on the development system only, afaik ... ... and don't use app_config.xml for CMS. no, I did not use app_config_xml; I made the setting for 2 cores in the web page. So the multicore tasks seem to be offered in the -dev system only, okay. But even the usual 1-core tasks are (still) not working at this point, obviously no jobs are available. But why does the project status page then show the usual number of "unsent" tasks (close to 200) - could it be that this includes the test multicore-tasks from the -dev system? Or does the "automatic task distribution stop function in case of no jobs available" not work? To me, everything seems to be a litte weird at the moment :-(
7) Message boards : CMS Application : CMS@Home difficulties in attempts to prepare for multi-core jobs (Message 49833) Posted 25 Mar 2024 by Erich56 Post: I changed my prefs to 1 task and max 2 CPUs. The task created a dual core VM with 2792 MB memory. After about 5 minutes a cmsRun appeared using up to 100% CPU and after another 2 minutes cmsRun started using up to 200% CPU. First test task: https://lhcathomedev.cern.ch/lhcathome-dev/result.php?resultid=3310818 I tried the same prefs which CP is describing above. However, without success - no dual core VM created :-( see here: https://lhcathome.cern.ch/lhcathome/result.php?resultid=408217329 what's going wrong?

Ivan, either they are used up already, or something else is going wrong. My hosts downloaded new tasks, but they don't work :-( Ivan, what's the current status on single-core jobs? Obviously, none available at this point :-(

Unfortunately some of the configurations are beyond our control, and we have to request changes as we find problems and determine a potential fix for them. We ask for your patience at this time while we work through the difficulties, and would fully understand if you chose to pause your participation in the project while we try to get on top of things. Ivan, any progress yet ?
20) Message boards : Theory Application : cranky: [ERROR] No output found - SOLVED (Message 49589) Posted 17 Feb 2024 by Erich56 Post: I was not aware that obviously ALL Theory tasks are faulty now. I downloaded them on several hosts, and all tasks errored out after some time, up to after more than 1 hour :-( So I am wondering why no-one back at LHC&Home stops the download of Theory tasks and empties the queue. The result is a real waste of ressources on the volunteers' side.
