Never mind, must have been traffic gettin in the way, downloads completed. I got an AP assigned last night and was watching the transfers tab and it took over 30 seconds for it to actually start receiving data, and when it did, I received it at 3MB/sec. I was actually waiting for it to time-out and retry, but then it started, finally. Linux laptop: record uptime: 1511d 20h 19m (ended due to the power brick giving-up) |

Never mind, must have been traffic gettin in the way, downloads completed. Well, thankfully, that's the exception rather than the rule these days. When I happen to be checking one of my rigs and some new tasks come through, I have to be pretty fast to click the downloads tab to watch them stream in.

I have noticed over the past few days that all my machines have one work unit that is in retry. When I hit the retry button they get downloaded fast. Maybe they go so fast now the server just loses track:) [/quote] Old James |

Looks like some more shorties going through the system. And once again the splitters are unable to pick up the pace. Ready-to-send buffer rapidly shrinking. Grant Darwin NT |

looking at the graphs of result creation for week there is a definate dropoff on 26-apr when I first noticed all the mb_splitters were renamed pfb_splitter. Not a major dropoff but noticible. |

I first noticed it about two weeks ago. |

I was actually waiting for it to time-out and retry, but then it started, finally. I figured it applied to everything, but AP is more noticeable to see what happens since the WU is much larger and takes longer to download. Pretty much one update interval for MB and the WU is gone, but at least with AP, it takes 3-5 UI update intervals before it finishes.

Almost out of CPU work. Most requests for work result in "Project has no tasks available" messages. The splitters need fixing. Grant Darwin NT |

+ 1, the splitters our next bottleneck? |

Maybe we are drinking the wrong bottles of Beer? Too many bottlenecks? If we switch to Cans of Beer would that help? |

Yes, Now switching to beer can, a 24 pack is a good start, I realy belive i need some, all my hosts are running out of GPU WU. |

Yesterday evening I had a feeling we were going to run into problems overnight. Ya, the MB splitters seem to have been running OK but with the AP splitters not running at full capacity problems were inevitable overnight. It seems like for a few days, things weren't too bad. But partial functionality on either of the splitters eventually results in problem. Maybe someone forgot to change tapes. It seems that they need to have 6 splitters of each type to keep up with work unit demand. |

I was running low until I hit the right moment, and got 69 new tasks. Apart from one solitary mid-AR resend, every single one was a shorty. They just get snapped up too darn quickly during a shorty storm - we need mid-AR or AP to damp things down a bit. |

They just get snapped up too darn quickly during a shorty storm - we need mid-AR or AP to damp things down a bit. Had a similar result with a lucky fetch. I'm out of AP and have mostly shorties, so my 83 gpu tasks sum to 2 hours of crunch time per BoincTasks. Have set up my zero resource share project for the maintenance window.

They just get snapped up too darn quickly during a shorty storm - we need mid-AR or AP to damp things down a bit. It seemed that for a few days there was sort of a nice mix of shorties, mid-ARs and AP work units. I don't know if anyone planned it that way or it was just random chance. With a decent mix, the system can almost maintain itself except until someone needs to change tapes - then it's pot luck. |

It is a game of hungry hungry hippos right now it would seem. With my 24 core box reporting a 3 hour queue it looks like it will be doing some PG work today once maintenance starts.
