Task validation
(Message 261)
Posted 23 May 2022 by Catchercradle Post: Maximum number of attempts for a work unit is I believe set when a batch of work is uploaded to the server. I don't know exactly where in the files uploaded to the server though. I see one of my tasks has _6 at the end of the task name indicating it is the 7th attempt whic seems a little excessive! |

Task seems stuck
(Message 238)
Posted 21 May 2022 by Catchercradle Post: https://boinc.loda-lang.org/loda/workunit.php?wuid=11768 on fifth attempt is stuck at 4.6% complete after over four hours. It is using 100% of a core according to top but no progress. One of the other attempts has it as abandoned which makes me suspect there is an issue with it even though one windows user has it completed waiting for validation. |

Posted 18 May 2022 by Catchercradle Post: I am getting the same error on all tasks on my main PC with a Ryzen 9 3900X CPU and 32 GB of RAM. I'm getting the errors both in Windows 10, and when I try running the project in a Linux Mint 20 virtual machine on that computer. GIT is installed in both the Windows 10 host OS and in the Linux Mint VM. Both the host and the VM have been rebooted multiple times for troubleshooting purposes. All of my computers with Intel processors appear to be working normally, both in Windows and in Linux. Nothing obvious looking at the Linux computer. By the way, if you truly want your computers to be anonymous the line https://boinc.loda-lang.org/loda/show_host_detail.php?hostid=319lets it be found by substituting 319 for the host number of one of their own computers in the url. |

Internet access needed when starting tasks.
(Message 189)
Posted 18 May 2022 by Catchercradle Post: I notice that unlike most projects I have tried, it is not possible to download tasks and then run them at a time when there is no internet access for the machine running them. If the router is turned off, all tasks error out a couple of seconds after starting. |

stats export
(Message 140)
Posted 15 May 2022 by Catchercradle Post: My guess is it won't be too long before they sort it out. There is a lot to learn on the BOINC server side and I imagine sorting out the problems with the tasks was/is a higher priority. There are a few things needing sorting out. I notice the Top Teams list is mostly missing for instance. Check pointing on the apps would be good too. |

Bugs :
Are there checkpoints?
(Message 139)
Posted 15 May 2022 by Catchercradle Post: The mining is stateless. Tasks don't need to finish to produce results. All findings are sent immediately to the server. So it is no problem if you restart in between.Except that if you exit BOINC, shutting down the client, the task then starts again from the beginning. It might not be a problem for the project but it does mean that for the tasks I had running yesterday evening, over twelve hours total of computation time was wasted. Adding checkpoints would allow tasks to be resumed from the point they had reached before the com;puter was shut down for the night. |

Posted 15 May 2022 by Catchercradle Post: Hello I noticed the time discrepancy on some of the tasks that were failing when /tmp was being used. No failures since then, however I do wonder if some of the earlier tasks that used /tmp have made their way back into the system? |

stats export
(Message 122)
Posted 14 May 2022 by Catchercradle Post: Reply on BOINC forum. First thing to check is whether the project is obeying GDPR rules and needs to have the account holder authorize exporting of stats to third party aggregation sites.I see that the project is on the list to be found by BOINC and doesn't need the url adding manually. I am not sure if that means the external aggregation sites know about the project automagically or not. I have asked that question over there. |

stats export
(Message 119)
Posted 14 May 2022 by Catchercradle Post: Where/how can I do this? My understanding from the BOINC forums is that you need to email the people who run the stats sites with the url of your stats page. There is a thread there about this project, I will ask in that because I don't pay much attention to stats myself other than to check whether something is working or not. Question asked here. |

Posted 14 May 2022 by Catchercradle Post: BOINC 7.16.20 (x64) Using top, tasks seem to peak at about 3.1% of my 32GB or RAM so about 1GB/task. I am running a maximum of 8 tasks at once as my experience with many projects is going into virtual cores can actually slow down throughput. |

Task names
(Message 102)
Posted 14 May 2022 by Catchercradle Post: I have several tasks on my machine in pairs with identical names apart from _0 and _1 at the end of the name. In other projects where the same task is sent out twice, there is a mechanism to ensure they go to different computers to validate results. |

Posted 14 May 2022 by Catchercradle Post: I have in the vm added boinc to the root user group to see if that makes any difference but will have to wait till boinc communicates with the servers again. Still all crashing with the same error. ran ~$ systemctl cat boinc-client.serviceagain and the same lines are still in the output so it clearly hasn't allowed write permission to the directory. |

Posted 14 May 2022 by Catchercradle Post: Now trying in a VM where I feel a little safer making some changes. Still the same problem despite having removed the line ProtectSystem=strictI suspect there is something I don't understand about how to allow BOINC access to /tmp |

Posted 14 May 2022 by Catchercradle Post: I used sudo systemctl edit boinc-client.serviceto add /tmp to the read write paths. Tasks running for longer 4 seconds instead of 1.something cpu time and around 50 seconds run time but still failing with 195 (0x000000C3) EXIT_CHILD_FAILED Edit: next stage might be to try it in a vm and change the line ProtectSystem=strict |
