This major new version of the Theory application follows a similar approach as the CMS application. |

Unsent 51 In Progress 0 When requesting work on my system: vLHCathome-dev 11 Apr 18:05:31 Sending scheduler request: To fetch work. vLHCathome-dev 11 Apr 18:05:31 Requesting new tasks for CPU vLHCathome-dev 11 Apr 18:05:32 Scheduler request completed: got 0 new tasks vLHCathome-dev 11 Apr 18:05:32 No tasks sent vLHCathome-dev 11 Apr 18:05:32 No tasks are available for Theory Simulations Something wrong with the configuration? |

The server has been restarted. If you still don't get tasks, there probably is a problem with the scheduler. |

4/11/2016 8:32:31 PM | vLHCathome-dev | No tasks are available for Theory Simulation Still no go. Is there maybe some confusion between Theory Simulation and Theory Simulation 64 bit? |

Another 200 Theory Tasks have been submitted. If this works then there is an issue with the way the BOINC scheduler is behaving with multiple applications. |

4/11/2016 9:20:32 PM | vLHCathome-dev | No tasks are available for Theory Simulation Still nothing. EDIT: i am also not getting LHCb tasks. 4/11/2016 9:48:25 PM | vLHCathome-dev | No tasks are available for LHCb Simulation |

We have hit this issue a few times, time to get to the bottom of it! It looks that that message is being sent by the send_user_messages() function which intern is called by send_work() in https://github.com/BOINC/boinc/blob/master/sched/sched_send.cpp |

EDIT: i am also not getting LHCb tasks. Yes, looks like you've broken LHCb as well ! |

Am i good, or what? Maybe i can break CMS tasks as well. Just kiddin. Maybe, disable CMS task for a bit and see, if the server can send other tasks, then. (or break CMS-tasks) |

CMS not broken yet, just got one :-) |

Maybe, it is related to the automatic topup of CMS-tasks, that kept the tasks to send at a constant value. Or, they are classified as "test apps", even though there is not tick box for that in the settings. |

I just got a theory task! I set the work buffer to max. |

We were using the make_work command but it creates work evenly so end up with different amounts of unsent tasks for each application. It also prefixes all tasks with wu_ so using create_work instead will also resolve this issue (I didn't forget CP!). http://lhcathomedev.cern.ch/vLHCathome-dev/forum_thread.php?id=114&postid=2419#2419 Rom just suggested using --allapps on the feeder daemon. Have just updated the configuration and restarted the sever so let us know if that helps. |

How long should that take to percolate through ? Not working at the moment. Only have 1 CMS task and preferences are for all projects, cache is at 4 days, only 1 cpu out of 4 being used. |

I got a second one, but they errorout after a few minutes. |

Can't get one on my laptop that has a CMS task running and nothing else. Just found I have one on another machine I swapped from LHCb earlier I left it to it (machines is busy running lots of other stuff). |
