After blocking all LHCb tasks on my Windows 10 PC I am running a Theory task and a CMS task. CPU use is close to zero. What happens? Tullio |

After blocking all LHCb tasks on my Windows 10 PC I am running a Theory task and a CMS task. CPU use is close to zero. What happens? Your CMS task did not receive any jobs from the Condor server. This suggests a network problem, but you did manage to establish network connections. It took much longer than usual for the task to realise it hadn't jot any Condor jobs; why that is, I am not knowledgeable enough to say. |

I had two tasks resulting in computation error. I've seen the logs and I agree with your opinion. What can I do? I switched back to Einstein@home where my RAC is 27k. Tullio |

All CMS, Theory,LHCb tasks fail on this Windows 10 PC with 24 GB RAM, 5.1.14 VBox, 7.6.33 BOINC. Only SixTrack tasks complete and are validated on this A10-6700 AMD CPU. It sports a GTX 1050 GPU board and achieves 27k RAC in Einstein@home. Tullio |

I went directly to Atlas@home, loaded 4 tasks and one of them is running on 2 CPUs taking about 55% with no other task running. So the problem is within LHC@home. Tullio |

Completed and validated. |

Two multicore Atlas@home tasks completed and validated and two more singlecore running. There is something wrong in LHC@home where all tasks fail with computation error. Tullio |

TCP port 4080 has to be allowed at your firewall (at least for CMS) since the project changed to WMAgent a while ago. Is this port open? |

TCP port 4080 has to be allowed at your firewall (at least for CMS) since the project changed to WMAgent a while ago. Frankly I don't now. But the behavior is the same both on the Windows 10 PC where I did not change anything in the default firewall and the Linux box running SuSE Leap 42.2, which has a different firewall, also at its default value. But how do those Atlas tasks communicate with the server? They are not blocked by any firewall. Tullio |

My idea is only valid if you use a firewall on your internet router. ATLAS does not use WMAgent and therefore not port 4080. The port overview can be found here: http://lhcathome.web.cern.ch/test4theory/my-firewall-complaining-which-ports-does-project-use |

Ports mentioned in stderr.txt for a CMS failed task are 80, 3125, 443 and 9618. All those connections are OK. Tullio |

Sorry, but I am running only Atlas, climateprediction.net. Einstein and SETI. No LHC,it does not work on my 3 PCs, two Linux and one Windows 10. Tullio |

Finally an Atlas task is running multicore through LHC with 55% CPU usage.All others fail except SixTrack. Tullio Memory used is 3000 MB instead of 4100 MB when going directly to Atlas@home. This through VirtualBox Manager. |

Multicore Atlas task completed and validated. CMS failed and Theory running with 2% CPU. Tullio |

Theory is now at 33% after 6 hours.I know it is not doing anything but at least I will get some credits which I deserve for signaling a problem with LHC. Tullio |

Theory fails, as it is right and I go back to Atlas, with two single core and two double core tasks. Tullio |

A Theory task on the Windows 10 PC has reached 56% after 10 hours doing absolutely nothing. Maybe I shall get some credits on it. Tullio |

Helo Tullio, saw in the details of your Win10-PC, that you have no paging-file in use. |

I admit being a Windows ignorant. I have swap partitions on my Linux boxes. How do I create a paging file? Tullio But in Disk Management a see a Page file. |

sorry in German: Systemsteuerung -System und Sicherheit - System - erweiterte Systemeinstellungen Systemeigenschaften Visuelle effekte, Prozessorzeitplanung und virtueller Speicher - Einstellungen - erweitert There you can define page-file. Sorry for German-Instructions. This is for Win10 pro. |
