I increased ncpus to 3. 3 tasks running and 1 ready to start. Limit on tasks in progress. <max_wus_to_send>2</max_wus_to_send> makes no sense now, because the host limit = 4. |

I increased ncpus to 3. 3 tasks running and 1 ready to start. Limit on tasks in progress. On the server max_wus_to_send is currently set to 1. |

I increased ncpus to 3. 3 tasks running and 1 ready to start. Limit on tasks in progress. Could you increase max_wus_in_progress to e.g. 16 and set max_wus_to_send to 2? |

Could you increase max_wus_in_progress to e.g. 16 and set max_wus_to_send to 2? The number of tasks is not limited to 8. I've 10 now. So you seem to be right. I don't know now, how to limit the number of wu's to the number of cores times N . . . |

Submitted an issue. For the time being, you want maybe reduce max_wus_in_progress to a for you acceptable number . . . 8-) maybe |

How about the science application not obeying the suspend by the user / BOINC wrapper? Issue submitted |

@Laurence Did the tasks below fail due to an app error or did you simply cancel them on the server last night to get the queue drained? https://lhcathomedev.cern.ch/lhcathome-dev/result.php?resultid=2753236 https://lhcathomedev.cern.ch/lhcathome-dev/result.php?resultid=2753243 |

App error. I pushed out a new version. |

I have set it to 4. The focus is on getting it working rather than throughput. As far as I can tell you have two quad cores CPUs, is this correct? This would mean 2*4=8. The comment in the issue suggests this parameter should be threads but it is not what we are experiencing. Will do some tests myself. |

As far as I can tell you have two quad cores CPUs, is this correct? This would mean 2*4=8 I have 1 quad-core (hostid=37) - 4 physical cores and with hyper-threading on it makes 8 threads. For BOINC 8 ncpus. The second quad you see is a Linux VM (hostid 3717) on the same Windows host setup with 4 cores/threads. In my preferences I've set 'No Limit' for Max # of jobs. |

As far as I can tell you have two quad cores CPUs, is this correct? This would mean 2*4=8 In the project db for your host I see ncpus = 8, so that is correct. In our project config we have: max_wus_to_send = 1 max_wus_in_progress = 4 Let me increase max_wus_to_send to 2 as see if you can get 16 tasks. |

After having 8 tasks loaded I get lhcathome-dev 21 Feb 10:49:11 This computer has reached a limit on tasks in progress We are in the same timezone, so you know, if that change was already made at 10:49 CET Meanwhile I returned 1 job, so 7 in progress, but lhcathome-dev 21 Feb 10:52:40 No tasks are available for Theory Simulation |

I have submitted more tasks.Laurence, do you remember we have had an issue with the project specific Max # of jobs? Although you had set 'No Limit', there seems to be a limit. Could that be 8? However yesterday, I got 16 on my Linux VM, when you raised max_wus_in_progress to 16. Weird. |
