Something you need to be aware of if your using a high amount of cores and trying to keep a bunch of ATLAS jobs in queue. You will need to put in an app_config file to restrict ATLAS to just 4 cores and 1 task otherwise it will try to run 2 jobs at 4 cores each and stall and blow up. I am trying to keep at least 3 ATLAS jobs in queue plus the active running one because of these server related settings that sometimes lead to not getting any jobs. But if I do that, then even the web settings of 4 cores does not restrict BOINC from trying to run at least 2 jobs simultaneously. Then you need app_config. Or at least in my case this is the only way it works. Maybe it is different for others? I run a 16 core machine and ATLAS tries to us 8 cores (4 per task) if I maintain a 3 job queue with one active. |

I am running native ATLAS, and have no problem running four ATLAS at once (two cores each). I have often run four cores each also with no problem with multiple work units. Maybe it is different on VirtualBox. |

I am running native ATLAS, and have no problem running four ATLAS at once (two cores each). That's interesting. I have room for 4 sticks. So the same brand, but also the same amount of memory per stick? |
