The results out in the field is over 6 million and it is still splitting fine (at a high rate). It still can't keep up, as it has a large backlog of "holes" to fill.Yep. Even with a 0.2 day cache setting, my Linux system is still unable to get work often enough to actually fill it's cache. Still taking 4-8 Scheduler requests to get any work. Grant Darwin NT |

Greetings, Is there any reason that, because of the lack of the 100 tasks per day per device limit, that my PCs don't report finished WUs regularly now? I have to manually do it with BT because they just add up and stick around. My Pis, laptop and tablet do not seem to be affected. They aren't getting any more WUs than they were before. They are reporting regularly. Have a great day! :) Siran CAPT Siran d'Vel'nahr - L L & P _\\// Winders 11 OS? "What a piece of junk!" - L.

my PCs don't report finished WUs regularly now?The PCs don't report work 'regularly': they contact the servers when they feel they want new work. If you were regularly asking for more work than the limits allowed (100 tasks per device), your PCs will have been perpetually hungry, and - like Oliver Twist - always asking for more. If they now have their fill, there's no need to ask so often, and nothing to trigger the early reporting. If there ever is any unreported work hanging around, it should be sent automatically after not longer than 1 hour. That's quick enough - you can relax your trigger finger. That reduction in the number of wasteful scheduler contacts (asking for work that will never be sent) might even be a beneficial side-effect of the new limits, once they've settled down. |

I'm more worried about post maintenance work reporting of that many work units out there. |

I hope we don't come to regret this.That's the million dollar question. Have we been given what we wished for, or is it just because something's broken? I guess it looks *fine* https://munin.kiska.pw/munin/Munin-Node/Munin-Node/index.html#setiathome |

https://munin.kiska.pw/munin/Munin-Node/Munin-Node/index.html#setiathomeThanks for that, I was really missing the graphs. Edit- is there one available for splitter output (Current result creation rate) & Results received in last hour? Grant Darwin NT |

At my last company, no new or changed software was ever rolled out on a Friday, Wednesday was preferred, as being the farthest point from a weekend.And i'd expect they did it on a stable functional system, not after a system crash. I've also seen mention of a gradual increase in work limits. To me, that would have been a 50% increase, then see how it goes for a few days (even a week), and if ok another 50% increase (over the original limit value). A 400% increase doesn't seem all that gradual to me. Grant Darwin NT |

maybe not the best methodology, but things are slowly coming back to normal. all seems ok right now. Seti@Home classic workunits: 29,492 CPU time: 134,419 hours |

Hi Richard, If you were regularly asking for more work than the limits allowed (100 tasks per device), your PCs will have been perpetually hungry, and - like Oliver Twist - always asking for more. If they now have their fill, there's no need to ask so often, and nothing to trigger the early reporting. I do believe I understand now. I had gotten back from the store and saw that I had about 60+ WUs to report. I went ahead and reported them. I was just gone watching a video for about an hour or so, about as long as when I was at the store, and there weren't nearly as many when I checked BT. I went ahead and reported them before I read your reply. Now, after reading the above explanation, I will just leave well enough alone. Thanks for this! :) Have a great day! :) Siran CAPT Siran d'Vel'nahr - L L & P _\\// Winders 11 OS? "What a piece of junk!" - L.

Looks like the Results in progress is starting to level off a bit now, so that should help things along considerably. Grant Darwin NT |

No, not really. I have 0 day additional cache setting and I only report crunched results every hour because I am way in excess of my normal cache settings because of the changes. Dropping the spoofed gpu count down considerably and also changing the daily cache level to get to 200 gpu tasks. Half a day only netted me around 130-150 cpu tasks after the change. Moved to 0.75 day for the primary cache. Seti@Home classic workunits:20,676 CPU time:74,226 hours A proud member of the OFA (Old Farts Association) |

No, not really. I have 0 day additional cache setting and I only report crunched results every hour because I am way in excess of my normal cache settings because of the changes.I understand that, but if you have a large Additional day setting, even when you drop below your "Store at least value" the work won't be reported till you hit the "Up to an Additional" setting. In my case, I have to report frequently, more than 70 tasks reported at a time after outages results in Scheduler issues and nothing gets reported, so I just have the Additional setting for 0.02. I'll see how things go when my Windows system gets down to the current cache setting, and my Linux system finally gets up to it. I'd like to have 24 hours work. As short as the weekly outages have been, it's still been taking the system a while to recover & build the Ready-to-send buffer back up. What the effect of the new server-side limits will be is anyone's guess. Ideally, none if everyone's caches are at their new maximum limits. But if they're low going in to an outage, i'd expect the after outage server recovery period to be much, much longer. Look at how long it's taking to get a Ready-to-send buffer again, even with the splitters working as well as they have for a while. Grant Darwin NT |

Hi Grant, I have my settings at "Store at least [ 1 ] days of work" and "Store up to an additional [ 0.5 ] days of work". Do I need to change either of those 2 settings? I believe I have the old Linux PC set that way too. Have a great day! :) Siran CAPT Siran d'Vel'nahr - L L & P _\\// Winders 11 OS? "What a piece of junk!" - L.

Leave the "store x days" as it is, but reduce the Store additional days" to a much smaller fraction, say 0.1, or even 0.02. This will ensure your cache remains fairly constant in size by being topped up regularly. Bob Smith Member of Seti PIPPS (Pluto is a Planet Protest Society) Somewhere in the (un)known Universe? |
