Toggleton, seeing the same. 238 MByte instead of 1.08 and 1.09 GByte. |

With Version 3.01 something went wrong. maybe more RAM needed. Yes, I know my OS is Darwin. I've allocated 12.8GB RAM. That's all you can have, the rest is allocated to other usage. Do you need more?? |

I don't think the ATLAS task like to be started and stopped. I didn't switch the tasks. That was the BOINC manager. After an earlier runaway, I: suspended the project; set no new tasks; aborted all existing tasks; tasks; unsuspended; reset the project; allowed new tasks. All tasks downloaded (8) were ATLAS of the same type. After >7mins of processing, the active task was made pending and a new one started. My task switching was set to "every 60 mins". I've set it to 9 hours. Have also set my preference only for ATLAS simulation FTB, and max of 2 jobs. But only when I've run down the Ubuntu VM I started in place of Darwin BOINC, as the VM has a few days of work on it at the moment. |

BellyNitpicker wrote: I: suspended the project; set no new tasks; aborted all existing tasks; tasks; unsuspended; reset the project; allowed new tasks. This is part of the problem since all logs are gone which may have included useful hints. So far the server shows successful ATLAS v2.03 logs but not a single one from v3.01. Suggestion: Run and report a Theory vbox task to see whether that succeeds - Theory requires much less ressources. Once Theory works fine, run a single ATLAS vbox task and let it send the logs back to the server. |

@David Cameron: The memory usage is not like expected. In ATLAS_vbox_3.01_job.xml the memory usage is set to 4000MB, but at the moment the old method for memory usage for VMs is still used: 3000MB + 900MB/core like 3900, 4800, 5700, 6600 . . . . 10200 for 1, 2 ,3, 4 .... 8 (unlimited) cores. |

@David Cameron: In slot directory there is a init_data.xml file where you can find line: <rsc_memory_bound>6920601600.000000</rsc_memory_bound> This is for my 4 core Atlas task.

In slot directory there is a init_data.xml file where you can find line: <rsc_memory_bound>6920601600.000000</rsc_memory_bound>Yeah, that's the old formula 3900MB + 4 * 900 MB = 6600MB = 6920601600 bytes On the development system we tested the new application with much lower memory and it was working fine even with 3000MB RAM, but here for safety it is set to 4000MB. However this setting in the xml-file is not respected on the production system. Until this is fixed you could lower the memory usage yourself by using an app_config.xml in the lhcathome.cern.ch_lhcathome-project directory. Example: <app_config> <app_version> <app_name>ATLAS</app_name> <plan_class>vbox64_mt_mcore_atlas</plan_class> <cmdline>--memory_size_mb 4000 --nthreads 4</cmdline> </app_version> </app_config> |

Once we exclusively run Run 3 tasks we can remove the memory scaling and use a fixed value of 4GB. |

We are still running the old Run 2 tasks here so we need the memory to scale up with number of cores. Once we exclusively run Run 3 tasks we can remove the memory scaling and use a fixed value of 4GB.In my opinion it does not matter whether it's a Run 2 or Run 3 task. In both cases the new ATLAS_vbox_3.01_image.vdi is used. I tested several setup's with 2, 3, 4, 5 and 8 threads with 'only' 4096 MB of RAM and all tasks were successful with almost no swapping. 8 threads: https://lhcathome.cern.ch/lhcathome/result.php?resultid=391160006 https://lhcathome.cern.ch/lhcathome/result.php?resultid=391160097 https://lhcathome.cern.ch/lhcathome/result.php?resultid=391459825 https://lhcathome.cern.ch/lhcathome/result.php?resultid=391459378 |

This is part of the problem since all logs are gone which may have included useful hints. Here is a log. I reduced the CPUs available to three, but left memory at 13GB. Two previously lost tasks downloaded, this time for 3CPUs. Both advertised their estimated duration as 4h20m. I ran one to conclusion, its actual duration was 35h15m. Remember that the 5CPU tasks also ran on for a very long time beyond their estimated time. NB. Prior to the events of the last week, I have been running Ubuntu VMs alongside BOINC on Darwin (with LHC as its only project) for more than two years without conflict or problem (Except for the short-term VBox memory leak in an earlier version of MacOS/Darwin). The three VMs have a total memory allocation of 12GB, so there's 7GB (give or take) left over for system activity.

There's still no log (stderr.txt) from an ATLAS task. BOINC manager's log shows that you did a project reset while you had tasks in progress. It also shows that you changed #cores from 5 to 3 which most likely crashed ATLAS. ATLAS is a multicore app and each task is set to a distinct #cores when the task starts. Hence, you must not change #cores while a multicore task is in progress. You have been asked to run and report a Theory task before you run another ATLAS task. Theory tasks are less resource hungry and even if they fail the stderr.txt reported back to the server may show important information. Hence, uncheck CMS and ATLAS on your prefs page until this is done. Now, to start with a clean environment it's recommended that you strictly follow this steps in order: 1. set all projects to NNT (no new tasks) 2. cancel all tasks from LHC@home that are not yet started 3. let all running tasks from LHC@home finish or cancel them 4. wait until all tasks from LHC@home are ready to be reported 5. "Update Project" to report them 6. On the project prefs page uncheck all apps but Theory 7. Also uncheck "If no work for selected applications is available, accept work from other applications?" 8. Set a small work buffer in your local client settings 9. If not tasks from LHC@home are left on your computer, reset the project 10. Allow work from LHC@home and request work 11. Set NNT once you got work 12. Run at least 1 Theory task and report it 13. Check whether that task appears on your computer's webpage: https://lhcathome.cern.ch/lhcathome/results.php?hostid=10667017 14. On the prefs page uncheck Theory and enable ATLAS 15. Repeat steps 10.-13. with ATLAS |

It looks like all ATLAS (native) tasks currently running on all of my computers: - are configured to process 500 events instead of 200 - are using input files around 570 MB each It would be nice to get a clear statement from CERN whether this is the new standard now. As far as I understand the discussion at -dev 500 eventers were just tests: https://lhcathomedev.cern.ch/lhcathome-dev/forum_thread.php?id=614 Options: - leave it at 200 - increase it to 500 - increase it to 2000 |

These new tasks, created just this morning with the download of 570MB and a HITS-upload of 190MB, are the awaited 'Run 3' tasks. With 'top' only one python process is shown with reserved memory of 2.4 G and almost 800% CPU for 8 threads. The monitoring with ALT-F2 is garbled with only showing one random worker out of 8 and scrolling a lot of lines every minute. The initializing phase of these tasks is lasting about 3 times longer. |

I can confirm we are now mostly running the Run 3 tasks. I asked for some test tasks here and got more than I thought :) These tasks are processing 500 events but each event is faster than before so the overall run time should be only a little bit longer. Also as you have noticed the console monitoring doesn’t work due to changes in the logging format. The “top†monitoring on Alt-F3 also shows a single python process instead of multiple athena.py processes. |

ATLAS Athena framework undergoes important renovation I hope the ATLAS project can set a smaller default memory limit for VirtualBox VMs that is appropriate for Run 3 tasks. |

I modified the command line to monitor ATLAS native 3.01: In this example, I used 2 CPUs per task hence the tail -n2. sudo watch -n10 "find /var/lib/boinc-client/slots/ \( -name \"log.EVNTtoHITS\" -o -name \"AthenaMP.log\" \) |sort |xargs -I {} -n1 sh -c \"egrep 'INFO.*Run:Event ' {} |tail -n2\"|sort -k 7,7"An example of output: 17:32:48 ISF_Kernel_FullG4MT_QS.ISF_LongLivedGeant4Tool 390 0 INFO Run:Event 450000:20848791 (200th event for this worker) took 82.67 s.

Nice! You got the idea and modified it according to your needs. +1 |
