As I aldready mentioned some WUs can pass validation in seconds. Then it is not problem of high number of results returned.
And again examples of WUs that are ready for validation from yesterday ... https://www.worldcommunitygrid.org/contribution/workunit/656161004 https://www.worldcommunitygrid.org/contribution/workunit/656365648 https://www.worldcommunitygrid.org/contribution/workunit/656240964 https://www.worldcommunitygrid.org/contribution/workunit/656067152 |

As I aldready mentioned some WUs can pass validation in seconds. Then it is not problem of high number of results returned. Actually, it depends on the work-unit number of the result returned, and the order in which the validators search for candidates! If they are searching in ascending order and you return a result for an older unit (e.g. you have just run a delayed retry [or a retry for a failed delayed retry!]) it'll validate quickly; if they are searching in descending order then newer WU results will validate quickly![Edit: I've checked back through results returned this year to date, and it seems that validations for older WUs happen first, so ascending order...] And again examples of WUs that are ready for validation from yesterday ... I think you'll find that the remaining Pending Validation issues have been cleared up now. Certainly, all your listed tasks have validated at the time I posted this! Once the number of work-units needing validation gets low enough, the validators cope quite well :-)https://www.worldcommunitygrid.org/contribution/workunit/656161004 https://www.worldcommunitygrid.org/contribution/workunit/656365648 https://www.worldcommunitygrid.org/contribution/workunit/656240964 https://www.worldcommunitygrid.org/contribution/workunit/656067152 All my "stuck on validation" units also cleared out some time earlier today (as have any "Waiting to be sent" retries I was waiting for!) -- I'd say "looking good" but I don't want to jinx it :-) Cheers - Al.

I have 450 pending validation - still a bit high I think- but I no longer see any "waiting to be sent" items and of that total only a handful are retries. They may still be a bit behind, but I think the onslaught of retries has now abated.

Probably you have again problem with MCM validation. Majority of uploaded WUs can pass validation in seconds but some of them waiting hours like this one from 2025-02-20 08:47:03 UTC
----------------------------------------https://www.worldcommunitygrid.org/contribution/workunit/667850087 ======== 2025-02-21 08:49 UTC - I see now close to ratio 50:50 between quick validation and long waiting in validation queue for no reason.

Yes, looks like one of the validators has stopped. Thought it would have cleared up overnight, but no, still lots of double 'pending validation' results i.e. mine and wingman both pv.

Validation queue for MCM again prolonging. Significant portion of uploaded WUs waiting there for hours with no reason.
Example waiting from 2025-02-23 23:38:21 UTC https://www.worldcommunitygrid.org/contribution/workunit/667262128 |

It's still the same this morning. Lots of results like your example, both rows stuck in pv. But others just validate straight away, like normal. I've not seen an explanation anywhere else?

correct, no progress after 24H
this problem affects MCM daily statistics for FEB 24 and also FEB 20 when we had the same issue. Statistics date Total run time Points generated Results returned 02/24/2025 ... 183:224:17:51:00 ... 419,133,612 ... 796,868 02/23/2025 ... 279:142:17:03:59 ... 661,410,781 ... 1,248,120 02/22/2025 ... 277:024:11:54:55 ... 652,291,928 ... 1,231,590 02/21/2025 ... 351:302:21:02:45 ... 827,604,378 ... 1,564,760 02/20/2025 ... 198:314:02:08:53 ... 473,339,672 ... 884,379 02/19/2025 ... 280:059:09:10:21 ... 640,505,861 ... 1,199,971 |

There are some recent messages in the "Are all MCM1 assimilators running?" thread that might shed some [unofficial] light on what is going on. As end users (and without a server status page) we can't know why it's happening, but we can get a handle on the symptoms...(Quick summary: it's related in some way to the fact that they run multiple copies of validators, assimilators and such like for most, if not all, projects at WCG.) Cheers - Al. |
