Assimilators not running. DB purge not running. AP not getting split. I have a bad feeling about this. Edit: Now the running gbt and pfb splitters are being culled. |

Oh dear, regular "project has no tasks available" messages in the event log, cache below 200, weekend coming up. Fingers crossed that the RAC will not take another dip, my stats graph is an amazing seesaw shape. |

Yeah, getting work is sporadic, the Assimilators are down, MB results awaiting validation are climbing (about 2 million higher than normal) and the Results & WU purge numbers are still flat-lined. But at least the splitters picked up their act! (although a couple of PFB and GBT splitters aren't running they're still doing better than they were). Grant Darwin NT |

And therefore, BETA with tons of AP's, is now a good option. . . Not if everyone scrambles over there and sucks them all out :( Stephen :) |

I assumed SETI Beta results didn't go into the master Database. Beta its for testing so wouldn't those results be invalid for the master DB? |

Oh dear, regular "project has no tasks available" messages in the event log, cache below 200, weekend coming up. . . Hi David, . . I got the "no tasks available" message a couple of times but now the GPU queue is quite full, even though they are 90% guppis. . . Better than nothing :) Stephen :) |

And therefore, BETA with tons of AP's, is now a good option.Q? Why are there AP tasks on beta? Is a new app out to test? Or GBT tasks? I don't see any mention of it in the beta boards ... |

I'm still having troubles with the Linux cruncher. Only get a handful of tasks every 3rd or 4th request and no where near enough to prevent the cache from steadily dropping. Down about 140 tasks now from full. Seti@Home classic workunits:20,676 CPU time:74,226 hours A proud member of the OFA (Old Farts Association) |

Hopefully the work will pick up enough to get you through the weekend until the guys are back in at Berkeley on Monday. Stephen :( |

What may I ask is "TBar's Triple Update"? The only trick I know that works most of the time is the "ghost recovery protocol" when the servers aren't responsive. Hasn't worked the last couple of times I've tried today. Seti@Home classic workunits:20,676 CPU time:74,226 hours A proud member of the OFA (Old Farts Association) |

What may I ask is "TBar's Triple Update"? Click on Update, and you'll get "Scheduler request pending, requested by user" As soon as it changes to "Scheduler request pending, requested by user, request in progress" then click on Update again. Wait for it to complete and as soon as you get the "Communication deferred 5:02" click on Update again. Then just let it be and on the next automatic update, work will come down. For the life of me I've no idea how or why it gets work, but It does. I used to muck around with the application settings and updating to get work- and even when that had no effect, the triple update would. It'd be nice if the Application preferences issues would be fixed (it's been almost 12 months now), but it looks like there are plenty more serious issues to be resolved first. Grant Darwin NT |

Do you have to set NNT before hitting Update? Nope, because you want new tasks, so you need to request them. Grant Darwin NT |

Scheduler is still messed up. Getting this on my most stable and consistent machine. Does that machine do AP work? I found with my system that not having AP installed & selected made it harder to get MB work. Even now, generally when there is plenty of AP, Arecibo & GBT work I don't have an issue getting MB work. When the AP work stops flowing, or most of the MB work is one type or the other, that's when I have problems getting work again. And it's mostly on my i7, the C2D generally chugs along (although it too occasionally has issues). EDIT- having said all that, something is screwier than usual with the Scheduler allocating work as I've had to do the triple update 4 times so far today to keep the work coming. And I wonder how long till we run out of disk space with all the WUs waiting validation & deletion accumulating? At least the rate of return for work has dropped down to 110,000/hr. Grant Darwin NT |

Actually getting the "reached a limit of tasks in progress" across all machines now. Caches falling ....... falllingg ...... fallliiinnnggg .... boom! I haven't had to resort to toggling off the AP project for a long time now. Guess I try that next. [Edit] Nope, that didn't work either.

I haven't had to resort to toggling off the AP project for a long time now. Guess I try that next. These days I just leave the "Use only selected..." and "if no work for selected" all on Yes. EDIT- noticed the cache running down again, triple update & 14WUs on the next automatic request. The way this issue manifests itself really is rather peculiar. Grant Darwin NT |

Thanks for the explanation. Do you have to set NNT before hitting Update?It only takes 2 updates, but it must be 2 that are NOT returning tasks in a row. The third is if you need to report something. It can be a bit tricky at times with fast GPUs to find the right time to make the 'nudge'. I generally don't have to nudge them often. When I seen your messages here I checked and was down >10% on them all. But they all recovered on their own since, some back down now. I very rarely see them drop below 66% without them recovering on their own. |
