Posted 16 May 2023 by Toby Broom Post: When I open the VirtualBox GUI theren is no media, since it doesn't run under my account it runs under the boinc account. I cannot su into boinc as there is no real account for boinc. I did rm * on all the stuff in .config/VirtualBox, now its back after aborting all the tasks and rebooting. |

Limit of 20 Tasks

Posted 4 May 2023 by Toby Broom Post: If you set Max # jobs &/or Max # CPUs to anything other than No limt then it could be there is a cap. Given how long the tasks take I'm not sure why you need such a buffer of work, I have 0.25 day of work and have 70 on my computer, 36 running and 34 buffer |

Posted 28 Mar 2023 by Toby Broom Post: Its was confimed in the presentation at BOINC 2023 conf, there will be a delay vs the CPU since there is some work to do, lots of work being done inside CERN uses GPU for XTrak |

Stuck WU: Waiting for the delivery of SIGUSR1
(Message 47863)
Posted 15 Mar 2023 by Toby Broom Post: My total all time is 2% and last 30 d is also 2%. My observation is though these stuck ones don't get any work so overtime you just end up doing no work as they all gave up trying to get work. |

Posted 15 Mar 2023 by Toby Broom Post: I just abort them, as discussed before, if you reboot the VM it can come back but once you have the error its time out getting a WU from the backend. I does on LINUX also just not as much I would say. |

Posted 3 Jan 2023 by Toby Broom Post: I tested it out and it doesn't work as expected. Either the webpage is the wrong one or it never loads up. I can use the screenshot function then OCR the picture to see what the console output but this is sub-optimal I would say. |

How to configure the maximum number of tasks and processes in project preferences
(Message 47544)
Posted 17 Nov 2022 by Toby Broom Post: I do all tasks with 1 CPU but atlas uses a lot of RAM due issue with how it works on windows. So with 32 GB of ram you can only run 3 WUs, as CP said you are probably better off to run a few more CPU / WU |

Posted 27 Oct 2022 by Toby Broom Post: 1. I aborted all the task and it came back, maybe as you say after reboot, so they would be restored from saved state. I didn't have any problems for a long time with 6.1, some issues I imagine with the 7.0 branch as it's new. |
