1.31GB vdi d/l |

That's the compressed size. The img has a prefilled CVMFS cache (~19200 files using ~2500 MiB). All of them are required to run the CMS app. Sending a small img with an empty cache (~400 MiB uncompressed) would mean that all those files would have to be downloaded at the beginning of the first CMS subtask. This would need additional 35-40 min per task compared to 2-5 min once for downloading the large vdi. The values are typical for my internet connection. |

Yes I am just mentioning the size of the original .vdi for each new version in case anyone wonders since I watch every one load and mine was just over 60 minutes this time. Of course after that the next tasks take seconds and start seconds after that. After they get running I check the running log to see when they are actually running jobs. That can take one or two hours. 100 events processed dumping histograms... 200 events processed dumping histograms... 300 events processed dumping histograms... 400 events processed............ |

Ok my first task finished Valid and it was a single core just for my first test and I saw Ivan also had one Valid with Linux so that is how I usually have to compare here since....... So now I have a 2-core started to see if it actually run 2 at a time. Some of us noticed that it wasn't actually running 2 tasks before BUT it did claim two cores and would even suspend running tasks so it could have those 2 cores.........including right from the start with those bad birds  . I will watch the running log to see how this goes and still let it run even if it doesn't run the 2 tasks |

Started running after about 1 hour INFO:root:CMSSW configured for 1 cores and 0 event streams Begin processing the 1st record. Run 1, Event 13610001, LumiSection 27221 on stream 0 at 07-Jul-2021 00:18:11.099 CEST But it looks like it is still running a one-core task even though my Boinc Man. says it is using 2 cores and VB man. says 00:00:02.995182 PcBios: [SMP] BIOS with 2 CPUs I guess I will find out when it is finished how much CPU time it has compared to Run time. |

Well this is what I got with the first 2-core https://lhcathomedev.cern.ch/lhcathome-dev/result.php?resultid=2996164 The run time is 17 hours 41 min and CPU time 14 hours 52 min So the only thing that looks multi-core is the Credit 1,198  |
