I wish we still have ATLAS long so I can configure a different thread count for the really huge ones, like the 2050 events. It took 40+ hours for the ones I've finished and there are still many running beyond that time currently. I would have given it 4x or 8x more cores if I knew the size beforehand. With such big variety in runtime, I can't easily find a balanced number to thread to keep runtime under control without having too many cores sitting idle during start. |

When using Atlas on 64-Core PC, have 10 Tasks with always 6 CPU's. Yes, the idle Time is for every AtlasTask (10 min at the beginning and 10 min at the end). David Cameron had it checked with the Science in the past, but not possible to change it. |

Seems to be that we are back on the old 400 event tasks where the Alt+F2 progress monitoring doesn't work properly.
