Notice from server
(Message 2417)
Posted 18 days ago by Bryn Mawr Post: I got an automatic notice that says "SiDock@home: Notice from server In Boinc Manager, advanced view, computing options, disk options remove all options apart from one - I generally set leave at least to 10gb so that Boinc has access to 240gb should it need it. |

Posted 28 Dec 2024 by Bryn Mawr Post: All of the tasks available at the moment are for ARM based machines. Odd, the status page is showing over 8,000 waiting to send. Try setting any other projects to no new tasks, setting the work fetch debug flag on, doing a manual update then reverse the first two steps. Then post the relevant section of the event log and we’ll try to advise. |

Temporarily work unavailabilities

Posted 20 Dec 2024 by Bryn Mawr Post: It seems that for the last few days there have been no work units available at all. All my machines are idle as far as BOINC goes. What's up with that? All of the tasks available at the moment are for ARM based machines. |

No long tasks
(Message 2373)
Posted 18 Dec 2024 by Bryn Mawr Post: SI-Dock have been saying for the past month that when the current target finishes (which it now has, the splutterings on the 17th were the last of them) then they would be moving to ARM only for a while. We can only hope that it is a short while. |

Server status page - percentage completion info
(Message 2318)
Posted 28 Sep 2024 by Bryn Mawr Post: Please do like the BOINC projects "Amicable numbers" and "RakeSearch", and add a "percentage completed" line to the server status page, either for the whole project, or for each application, as well as a completion estimate (year and month), based on the current speed. From the server status page :- Research progress Target 11: corona_Sprot_delta_v1 (%) 47.257 Target 22: corona_RdRp_v2 (%) 99.994 Target 23: ebola_GP_v1 (%) 15.373 The last figure is the percentage complete for the target. |

Is it possible to turn on the setting "Max # of simultaneous tasks" ?
(Message 2251)
Posted 19 Apr 2024 by Bryn Mawr Post: Note that the <max_concurrent> tag in the app_config.xml file sets the maximum number of tasks of a specific application to run at a given time. It does not control the work cache size, meaning if you set the max_concurrent to "2" say, it will download tasks to fill whatever cache size and the cpu thread to use that you specified. It will only run 2 tasks irrespective of your cache size. However there is a bug in the boinc manager (not sure what version that is) that could potentially load more tasks that you need and override the cache size. Just fyi. As pututu has said, it will limit the client to running 1 task at a time rather than requesting one task at a time but because the scheduler then knows that it only has one core to play with it will restrict the number of tasks requested as well. Indeed, with a small cache, what tends to happen is that it will only request a new task shortly before the existing task completes. I’m running 5 projects (of which 3 are currently supplying work) and it works well for me. |

The bug has been fixed in the latest versions of the Boinc Client. Even before that, I have been running max_concurrent with a small cache size for several years without a problem - each project (including SiDock and CPDN) working according to their project weighting. (If anything it’s WCG that overfills the cache with respect to its project weighting). |

Posted 18 Apr 2024 by Bryn Mawr Post: Thank you for reply @pututu. Let me clarify Set up an appconfig.xml file in the SiDock project directory with a max_concurrent command :- https://boinc.berkeley.edu/trac/wiki/ClientAppConfig |

Posted 21 Oct 2023 by Bryn Mawr Post: Due to a wasp infestation whilst I was away from home both of my desktops crashed, one being dead for 9 days and the other being dead for about a week, up for an hour or so (in which time it aborted the SiDock tasks it had been working on and then loaded a new set) before crashing again and being down for 14 days. When I sorted the problem the existing tasks ran to completion in the normal 24 hours(ish) and were granted the normal 1,000 to 1,500 credits. All the tasks downloaded after the recovery have run successfully in the same timescale but have only been granted 100 to 150 credits. As soon as I noticed this I ran benchmarks on both machines guessing that the values had reset but tasks downloaded after the benchmark are still being granted reduced credits. Is it only me or has there been a change in the past week or so? |

Posted 28 Mar 2023 by Bryn Mawr Post: I have just restarted my secondary pc after a year’s absence and I’m seeing many WUs crashing with the above exit code, mostly after a few seconds.

(So far no WUs have successfully completed but a couple are running ok). I shut down the pc, removed the memory and cleaned the connectors, reseated the memory and restarted. Since then it’s run clean overnight so I think it was just that the machine had been sitting unused for too long. The WUs that are running should complete soon and I’ll confirm when they do. |

(So far no WUs have successfully completed but a couple are running ok). The system is a Ryzen 9 3900 with 16gb ram and 256gb nvme running Ubuntu 22.04 and Boinc 7.18.1. My first guess is memory, maybe fuzz on the connectors but I thought I’d ask if anyone had had similar problems? |

Posted 3 Mar 2023 by Bryn Mawr Post: My R9 3900 averages about 40 so that sounds about right. 40 credits an hour seems to be normal across the projects I work. Sometimes better when a new type of task is introduced but there or thereabouts. |

Posted 3 Mar 2023 by Bryn Mawr Post: I'm averaging just around 29 points per hour with this cpu. Full resources committed .. running Linux .. at 4.5Ghz. My newer Ryzen 5700's produce considerably more, over 52. Are there optimizations (SSE,AVX, etc) missing with the i7 which explains the considerable difference? My R9 3900 averages about 40 so that sounds about right. |
