Posted 23 Mar 2024 by Richard Haselgrove Post: Is that what happens with most projects with the server code Richard?Yes. I have a current RAC of 874.09 at SETI@home - which stopped issuing new work in the Spring of 2020. Ironically, this project was an outlier until last year. It used a special, bespoke, credit handling system, which did keep the figures updated during a work drought. - but that system was desperately inefficient, and placed a heavy load on the project's servers. It was replaced (with a few bugs, which we've now ironed out) with a new bespoke system which brought us closer to the standard BOINC framework. But that framework has an unspoken assumption that no BOINC project ever runs out of work or closes down ... Edit - SETI RAC table |

Posted 23 Mar 2024 by Richard Haselgrove Post: The list is kept up to date with each individual's current figures. The problem is that the "current figure" only changes when the user in question is actively processing new work - and there hasn't been a lot of that recently. Hopefully, that will change soon. |

Posted 23 Feb 2024 by Richard Haselgrove Post: What can we do about systems like host 1549227? The anonymous owner grabbed 16 tasks for their 8 core Ryzen on 19 February: 13 of them have returned just one trickle each since then. One has crashed, showing many, many quit requests from BOINC: I got the resend, which is how it came to my attention. |

Posted 21 Feb 2024 by Richard Haselgrove Post: Or, since all CPDN applications will be floating point intensive, and will all suffer from FPU congestion on a hyperthreaded CPU, you could use the single project-level tag instead: <project_max_concurrent>N</project_max_concurrent>For a full list of the available options, see the BOINC user manual. |

Stats missing
(Message 70487)
Posted 20 Feb 2024 by Richard Haselgrove Post: From your account home page here, there is a link to "Preferences for this project". Or you can get there directly from https://www.cpdn.org/prefs.php?subset=project (you can't get there directly from the navigation bar above these posts, which is a BOINC mess-up) In the first group, there is a check-box for "Do you consent to exporting your data to BOINC statistics aggregation Web sites?". That must be checked before the stats appear externally. Stats are only exported once e day, so they may take a couple of days to show up - but they will go back to the beginning of your time here when they do show up. |

Posted 18 Feb 2024 by Richard Haselgrove Post: Download a new task, then suspend either the task or all computation before it gets a chance to run. Look to see if the .exe was quarantined immediately on download. If so, restore it and use whatever tools the AV program provides to say "I trust this file". If it wasn't flagged immediately on download, look to see if the AV provides an option to scan a single file on request (most do). Scan it, and respond to any warnings/options it generates. Again, the idea it to get to the point where you can say "I trust this file". Only then allow the task to start running. |

Posted 15 Feb 2024 by Richard Haselgrove Post: Can these half done workunits be handed out to others to complete? I've never been given a smaller workunit. Sounds like it should be possible. If my CPU can continue where it left off after rebooting the computer, why can't your CPU take my half done unit and continue it?Restarting after a reboot relies on the presence of checkpoint files on your local hard drive. CPDN uploads data zips (intermediate weather reports) 24 times during each task in the current batch, but only one 'restart' file at about the mid-point. Glenn can confirm the technicals, but I would guess that a short completion run would only be feasible if the original host had uploaded that restart file before failing. |

Posted 15 Feb 2024 by Richard Haselgrove Post: There were problems at the beginning of the month, as discussed in this thread, but they seemed to have been cured. It is possible that there was another temporary glitch just as you were trying to attach: the quickest way to check the status of https://climateprediction.net is to click on the banner at the top of this page. It opened for me just now (although slowly): it might be worth another attempt now. |

EAS batches 1001-4

Posted 15 Feb 2024 by Richard Haselgrove Post: Particularly plausible because yesterday was 'patch Wednesday' in UTC: the Wednesday after the second Tuesday of the month. That's the usual day Microsoft releases major update packages - even large security update packages for Windows 7, which is otherwise out of support. |

Posted 14 Feb 2024 by Richard Haselgrove Post: Had a quick grok before going out to the pub, and found a relevant message board post (SETI NC 1641898 - nine years ago today!). I did look into the possibility of whitelisting when this question was raised after the release of v0.43 last year. It turned out to require considerably more identity and security checks than opening a bank or PayPal business account, and I found I couldn't possibly qualify in any event (I don't run a personal website with my home address checkable through a WhoIs lookup on the domain name). |

Posted 14 Feb 2024 by Richard Haselgrove Post: It would be most helpful if we could identify which anti-virus products are reporting a detection. That won't ever be identifiable in your server logs: we would probably have to crowd-source it by an appeal here. So: if anyone here has noticed an AV alert relatable to CPDN since the new tasks were released, please post details here. I don't have any recent experience of a central, industry-wide, reporting point, although I have written and released software installation packages in the past which have triggered similar problems. Unfortunately the BOINC message board most likely to have searchable records of such events (SETI@home) has been offline all day, although it's back now. I'll put my thinking cap on in the morning. |

(Message 70379)
Posted 14 Feb 2024 by Richard Haselgrove Post: I think a more likely explanation is that the potential wrong 'un is being detected by heuristics, rather than by pattern matching. Modern AV products often have a module which examines the behaviour of the beastie in questions like:
The remedy is the same - check your AV messages and logs, and report any false positives as quickly and as often as you can. They usually get the message after a few days. |

Communication deferred
(Message 70365)
Posted 13 Feb 2024 by Richard Haselgrove Post: The project-set deferral period at this project is 1 hour (3636 seconds), whatever the outcome of the update. New work will never be issued if you request it during this period. You need to look more deeply (BOINC's Event Log is recommended) to see the state of play. |

Posted 13 Feb 2024 by Richard Haselgrove Post: I mentioned some time ago that my travelling laptop crashed a test task with the old app, with a signal 11 at startup. That host is approaching 10% on wah2_eas25_h0k1_201012_24_1006_012259529_0. I also have a tiny, low power, Celeron box (about the size and shape of a portable CD library) - picked up to test a 64-bit BOINC error on some low power processors, now resolved (host 1548871). That one is also running a task successfully, but has only reached 3% over the same timescale. |

Posted 9 Feb 2024 by Richard Haselgrove Post: Looking at a few more of the names on the 'top participants' page, the are plenty whose computers aren't hidden. You can usually work out why the figures haven't changed: some only run CPDN on Linux, others have multiple computers registered but they haven't contacted the servers for a long time. My own figures (buried several pages down the list!) seem to be fully up-to-date. |

Tasks : Didn't need
(Message 70331)
Posted 8 Feb 2024 by Richard Haselgrove Post: That's a task from Batch 1004. The scientists found a problem with the way that batch had been set up, and cancelled it so people like you didn't waste time working on a task which wouldn't provide any useful answers. That also applies to batches 1002 and 1003. They will be re-started later, when the science has been corrected and checked: we don't yet know exactly when. |
