ATLAS seems to block my BOINC. I got a few days ago two WU with a presumed calculation time of 00:01:34:59 each, but it doesn’t calculate anything, the processor is doing nothing. Other projects like PrimeGrid in my case is stopped as well, no calculation. not downloads. Setting the LHC@home to pause, PrimeGrid starts calculations immediately and if necessarily downloads new WU. Resuming LHC@home stops calculating everything.
There is plenty of disk space and enough reserved for BOINC. So, which job cache is meant? My fault? Bad WU? |

In the Atlas-folder is Yet's checklist. You can check the list to see what went wrong. |

I guess you are using standard settings. In this case ATLAS vbox is automatically configured to create a VirtualBox VM that allocates 8 cores and 10200 MB RAM. Far too much since your computer has only 12 GB RAM. You may go to this page: https://lhcathome.cern.ch/lhcathome/prefs.php?subset=project Set "Max # CPUs" to 4, cancel all ATLAS tasks you already have downloaded and request fresh work. |

That check list is a very good idea. I am going to take a guess that the VM created for Atlas is taking about 10Gb of RAM and the number of processors is set to 8 within the VM. Go to your LHC preferences and set the following below. This will run one Atlas task with the minimum amount of RAM required and create a VM with a single processor. You probably have to set no new tasks for LHC, abort any current Atlas tasks, exit and restart boinc after changing your preferences. I looked up your processor and you have 4 true cores. That is the highest you should set your Max # CPUs to. You might need to look at a different sub project, rather than Atlas Max # jobs 1 Max # CPUs 1 |
