what does "timed out" status mean?
(Message 51491)
Posted 2 Feb 2025 by rob Post: Deadline is, for most projects, the time the task should be completed, returned and reported to the project. Some projects do give a bit of lee-way, but not all. [edit to add] Both your recent tasks that failed due to exceeding the deadline were sent out to others within a few minutes of the deadline, one has already been completed, returned and validated. |

(Message 51487)
Posted 1 Feb 2025 by rob Post: Exactly as you surmise - your version of that task is dead, and so you might as well abort it. This message appears when the task has been on your computer beyond its deadline. One way to reduce the possibility of this in the future is to have a small cache, but even this is not guaranteed to work if your PC is slow or only runs BOINC for very few hours a day. |

Lots of strange messages: 2024-11-24 13:37:11 (7136): Guest Log: *** Starting ATLAS job. (PandaID=6416690328 taskID=42161013) *** Then after a few more lines I get:

(Message 50745)
Posted 8 Oct 2024 by rob Post: We don't have access to your computer names which makes it difficult to work out which of your computers you are talking about. That said if you follow this link https://lhcathome.cern.ch/lhcathome/hosts_user.php you will wee your list of computers and be able to work out which is which. After selecting the computer you want to look at you will see there's a few filters, select the "error" one and you will only see tasks that ended with an error, then its simply a case of selecting a task in the list (I'd suggest that you are looking for the most recent one), scroll and near the top of the information is the error number you are looking for, scrolling down the page is all the detail of the error (mostly groups of repeating lines which may mean something to others) |

Posted 7 Oct 2024 by rob Post: Make sure you don't have the Windows own "version" of virtualisation installed. Crudely there are two "types" of virtualisation, and they don't always work well together. It's a bit of a pain to make sure that the Windows one (Hyper-V) is not installed - it sometimes gets installed without you doing anything :-( The best thing I can suggest if for you to do a web search for "removing Hyper-V from Windows x" and follow the instructions step by step (it may take several re-boots). |

Questions and Answers :
Windows :
you need Virtualbox installed and virtualbox extension pack or your tasks will be "error"
(Message 50452)
Posted 25 Jun 2024 by rob Post: I've sat around watching the debate about the need or otherwise for the extension pack under windows. The short answer is yes or no, depending on you wanting to spend time watching tasks run or not. Simply put, if you want to keep a close eye on tasks as they run then you do need the extension pack, but if you don't want to watch tasks running then you don't need the extension pack. Evidence? These few lines from a recent successful task (https://lhcathome.cern.ch/lhcathome/result.php?resultid=411995370)
The next couple of lines show that communication to the shared disk space is OK: 2024-06-25 08:06:38 (36756): Enabling shared directory for VM. |

(Message 49924)
Posted 10 Apr 2024 by rob Post: The AMD Ryzen 9 7900X has virtualization support, but this is turned OFF by default, and report "virtualization not supported". Check in the BIOS that virtualization is enabled, then turn it ON. After rebooting that error message should disappear, however other messages may then appear, which may take a fair bit of work to clear them. Most common is trying to run the "BOINC supplied" form of virtual machine on a computer that has (or has had) the MS version of Linux installed, the two just aren't compatible with each other despite having very similar names.... |

(Message 49793)
Posted 20 Mar 2024 by rob Post: I had the same problem. There is a work-around that appears to work: Suspend the project before shutting down BOINC, then I can safely turn the computer off. This forces Virtual Machine to first stop processing the task then saves the Virtual Machine so it can restart at a later date or time. (And I agree with you about wanting native tasks rather than VM -based tasks - life would be a little easier). |

New native version v300.08
(Message 49419)
Posted 6 Feb 2024 by rob Post: There is something strange going on with the initial estimated run time vs. the actual run time of some, if not all of these tasks: On my PC: Initial estimated run time = 61.5 minutes During the first 60 minutes of running the elapsed time increments at about 1second per second of clock time, and continues at this rate - only a couple of seconds out after an hour. However the remaining time only drops by about 15 seconds to 60.25 minutes. At 61.5 elapsed minutes the remaining time jumps to 9 days 23 hours and 46 minutes. This has the effect that my computer downloads a number of tasks that are, initially predicted to be finished by the deadline, but at the "1 hour" adjustment the majority will not even be started never mid finished by the deadline (10 days). This is potentially a rather unproductive waste of bandwidth, not to mention frustration for me. It will be interesting to see what the actual run time of these tasks is. |

Posted 3 Feb 2024 by rob Post: Well...... WSL uses "type 1" virtualization, but that is totally incompatible with the "type 2" virtualization used by the Oracle system deployed by LHC. As far as I can gather it is not possible to have both "type 1" and "type 2" virtualizations running on the same PC. It may be possible to do some form of dual boot allowing you to boot into either a "type 1" environment or a "type 2" environment, but I don't think either configuration would allow the other to run at the same time. |

Posted 2 Feb 2024 by rob Post: You have the same set of issues I had. Something (Microsoft??) decided to sneak in an update which launched Hyper-V and Hyper-V prevents Oracle VirtualBox from running. The not so simple solution is to unpick Hyper-V from your system (you need admin privileges), it can take a few re-boots to get rid of the last vestiges - search for "removing Hyper-V from a computer), allow an hour or more. |

Posted 1 Feb 2024 by rob Post: "Just turn OFF".... 40 minute later, several re-boots and I'm seeing the first LHC ATLAS simulations downloading, along with the expected(?) ATLAS v-box image (all 1.7GB of it). OK, sit back and wait for the next fun instalment, but for now I think I've earned a drink. |
