+ 1, the splitters our next bottleneck? It would appear so. Just coming back from the outage, there is only 1 splitter running, and it is only producing 6 Wus/sec. With shorties we need at least 55/s. So we really need 10 PFB splitters, and there are only 6, and it's been a while since they've all been running. No wonder we keep running out of work, even while it is being split. Grant Darwin NT |

+ 1, the splitters our next bottleneck? All the splitters are now running, and they're producing less than half the rate of what is needed. Grant Darwin NT |

Hungry GPU's sitting here doing nothing! Ho Hum! |

Just got a "Project down for maintenance" and a one hour backoff, so something's underway. Another Fred Support SETI@home when you search the Web with GoodSearch or shop online with GoodShop. |

My main cruncher just downloaded 98 GPU tasks, but my second one still can't get any. |

And what is this 90 Mbits/sec upload that's running 24/7, even when the project is down for maintenance? http://fragment1.berkeley.edu/newcricket/grapher.cgi?target=/router-interfaces/inr-211/gigabitethernet6_17&ranges=d%3Aw&view=Octets |

And what is this 90 Mbits/sec upload that's running 24/7, even when the project is down for maintenance? I don't think anyone ever guaranteed that that link was exclusively for seti@home. |

The MB splitters are certainly having a hard time getting up to their usual speed. Cheers. |

And what is this 90 Mbits/sec upload that's running 24/7, even when the project is down for maintenance? By the nature of a gigabit router interface, that link must be for SETI@home exclusively. My guess is the backup operation which is the reason for the Tuesday outage is sensibly being done to someplace outside the colocation facility. Joe |

Still no work, but then I thought the outrage was over? The T1 Trust, PRR T1 Class 4-4-4-4 #5550, 1 of America's First HST's |

Never thought I'd say this - Please Split some AP's to slow down the feeder, Link and Client systems. |

And what is this 90 Mbits/sec upload that's running 24/7, even when the project is down for maintenance? then lets program the upload and download servers to report data rates and output on status page. |

What screams at me looking at the Munin graphs is that only when we ran out of AstroPulse units did the MB units start to plummet from 300K to 0. This suggests to me that a lot of GPU AstroPulse is being done and when that ran out the MB reserve was quickly devoured by hungry hungry GPUs. It's interesting that 30 units/s creation rate isn't enough, at least during a shorty storm. "Life is just nature's way of keeping meat fresh." - The Doctor |

This suggests to me that a lot of GPU AstroPulse is being done and when that ran out the MB reserve was quickly devoured by hungry hungry GPUs. I noticed this too before the shutdown. When MB and AP units were both being split, things kind of behaved themselves and I got all the MB I could crunch. I sure hope this is fixed tomorrow. The current server status page shows 6 MB splitters active. 8 were active earlier and couldn't keep up. This is very frustrating for dedicated Seti crunchers like me. |

It's interesting that 30 units/s creation rate isn't enough, at least during a shorty storm. During a shorty storm 55/s is the minimum needed to meet demand. The storm is over, but still the splitters aren't able to crank out enough work. For a while they were doing about 30/s (barely enough when there's a lot of VLARs in the mix). Now they've dropped down to less than 20. Someone in the lab needs to take a look at what is going on- the splitters used to be able sustain 70/s no problems at all, now they can't even reach it as a peak. EDIT- at least the shorty storm was over for a while. The work my systems were able to get after the outage while i was at work didn't have many shorties in it, but one of the systems was just able to get some more work (still nowhere near enough...) & it was almost all shorties.

It's interesting that 30 units/s creation rate isn't enough, at least during a shorty storm. Dunno...for 10-20 minutes, they were down to 10-15/second. You can see the resulting dip in the cricket graphs. I was kinda hoping they would add another one of them fancy new pfb splitters during today's outage, seeing as how the AP splitters have been far outrunning them as of late. Last check, they were getting close to 30 again. Might be something with the new pfb splitting thingy, although I think it was Richard that expressed the opinion he thought they might be a little faster than the old splitters.....hmmmmmm. Might depend on the work they are splitting. "Freedom is just Chaos, with better lighting." Alan Dean Foster |
