Actually that should have read "167.6120/sec" but for some reason the 1st digit went AWOL. Yeah, i knew what you meant. :-) I'm wondering if it was an actual value, or just an anomaly? You'd expect a small beuffer to develop with that sort of output. But i guess if it was brief enough, whatever was produced would be gone before the next query & so wouldn't show up in the ready-to-send numbers. Grant Darwin NT |

Strangely enough, despite the apparent lack of work I've been bouncing off the limits on all three of my crunchers. I just don't understand what's going on with the splitters and downloads.

It must be all those 4-5min shorties that we've been chewing through lately (I'm reporting 12 every 5mins across my 2 rigs just off their video cards alone). Cheers. |

Has DA done something and not told anyone?? The problem is to do with the Seti servers, not the BOINC clients. Grant Darwin NT |

It was the first 0 (zero) I have seen in that field, sort of prophetic at the moment. |

The problem is the databse & the only real fix will probably be to re-design it from scratch. Isn't that the way it is now? The Master BOINC database keeps track of all the work in progress, as well as User IDs & stats, and the Forums. Once a Work Unit is completed and validated, the canonical result is assimilated into the appropriate Science Database, and Work Unit and associated Tasks are deleted from the Master BOINC database. It has been suggested that the Forums be moved into a separate database, but that idea was nixed, for reasons I don't recall... Donald Infernal Optimist / Submariner, retired |

Am I glad that I am currently living in this part of the world. Electricity is included in the apartment rent, no matter how much I use. I pray it stays that way for a looooooong time.

Has DA done something and not told anyone?? He often does...LOL. At least not publicly. Maybe in the dev forums, which are not frequented by most of us. "Freedom is just Chaos, with better lighting."

I can't afford to be cutting edge, my last power bill just arrived.... Impressive. Even the kitties have not been able to burn a hundred K electric bill. Of course, that depends on the KWH rate. Once this spring turns into summer, I will have to do any and all crunching at night rates. The heat will just not allow anything else. "Freedom is just Chaos, with better lighting."

The problem is the databse & the only real fix will probably be to re-design it from scratch. Don't know. There have been times in the past, for various reasons, where the number of results in progress was much higher than when they started to have issues with the databse. But back then, there were many less completed & validated results which would make a single databse much larger now than then. Having 2 databases, one of which being active would only grow with more clients/computing resources which hasn't changed that much over the years, which is why i thought the present database includes results that have already been validated.

Like I have stated before the colo.... I did say that once things settled, there would be a new wrangling of bottlnecks. This is not a bad thing, you see. Once bandwidth has been removed from the equation, the true nature of things has been revealed. If the kitties cannot get enough work to keep them busy, there will be a settling out of sorts, where all the work that the project can hand out will be crunched. We just now need the ntpicker to sort it all. "Freedom is just Chaos, with better lighting." Alan Dean Foster |

According to the new Haveland graphs, 'Results received in last hour' (the blue line on that page) hasn't dipped below 110K for 30 hours solid - in fact, it's averaged more than that for the whole of the last week. That's nearly 22 million results in the 8 days covered by the weekly graph. And whatever gets returned, has to have been sent out first. That's one hell of a hammering the servers are getting - kudos to all involved. |

That's nearly 22 million results in the 8 days covered by the weekly graph. And add to that the numbner of AP WUs in progress & the number returned per hour are approaching as high as they have ever been before as well. That's a lot of work for the servers to handle.

Results returned in the last hour has fallen to 100,000 (still 30,000 more than usual), and the Ready-to-send buffer has actually started to recover. Just had a look in my work queue & there are a few GPU units that will take more than 3min to crunch. Not many, but some. So the shorty storm continues, but at least it's abated a bit.

I just had a look in my hosts and the GPU's have a boatload of shorties. Have a lot of Ap's though. I like AP's especialy in the 550TI can run one in 4 hours. [/quote] Old James |
