The weekend was a difficult as we kept splitting noisy/fast work, so our back-end production was running full speed most of the time, clogging several pipes, filling some queues, emptying others, etc. We were able to keep reaching our current outbound ceiling of 60 Mbits/sec, so despite the problems we were sending out work as fast as we could otherwise. That's good, but bigger pipes would be better. Also one of the assimilators was failing on a particular result. We're not sure why, but I deleted that one result and that particular dam broke. Some untested forum code was put on line which also wreaked minor havoc. Not my fault. Anyway.. this is a short mini week for us in between Xmas/New Year's. Since we weren't around yesterday, we had our normal weekly outage today. Also took care of cleaning some extra "bloat" in our database. About 20% of the rows in the host table were hosts that last connected over a year ago and ultimately never got any credit. We blitzed all those. Upon restarting everything this afternoon after the outage I noticed the feeder executables had disappeared sometime around 3-4 days ago (luckily images of the executables remained in memory since we had no downtime over the weekend). We have snapshots on that filesystem so recovery was instantaneous, but the initial disappearance is mysterious and a bit troubling. - Matt -- BOINC/SETI@home network/web/science/development person -- "Any idiot can have a good idea.

A Job Well Done Sir . . . nice going Matt (and the others @ the lab) note: Favourite day of the week: Tweenday, the magical day between Tuesday and Wednesday, when those of us with faerie blood flit around the sleeping earth righting wrongs and playing pranks. We give leg-cramps to the wicked, lovely dreams to the virtuous but unhappy, and stifle in the crib those babies who are likely to grow up to send e-mail questionnaires asking things like 'What is your favourite day of the week.' © 2007 Michael Horatio Kelly ;) BOINC Wiki . . .

Excellent job as always. Have a shot of my large Jack Daniels bottle that Santa deposited in my stocking. You have earned it guys! Thank you. |

The servers are just getting back up to speed, after the 24hr delayed Tuesday maintenance period, see cricket graphs |

We have snapshots on that filesystem so recovery was instantaneous, but the initial disappearance is mysterious and a bit troubling. Missing files like that prompt me to make an immediate fsck on the filesystem. Too many crashes under my belt. I hope you had a Merry Christmas. |

Why are the bits 'in' larger than the bits 'out'? I would have thought it would be the other way. Isn't the downloading of wu's the greatest demand on the network? |

...see cricket graphs Because the monitoring point is the campus end of the link from Space Sciences Lab. The bits 'in' to your computer (WU downloads) is also larger than the bits 'out' (result uploads) for the same reason. Joe |

Because the graph is taken from the point of view of the router. So for that interface the "bits in" are coming "in" from the SETI servers and the "bits out" are the ones being sent back to the SETI servers. If they were monitoring the port on the switch on the other end of that piece of cable (or fibre) then the graph would be reversed. (Long time reader - first time poster. Finally I can add something to the forum!) |

the interface gigabitethernet2_3 is looking towards the seti servers so packets in and packets out are reversed the interface gigabitethernet5_1 is looking at the internet so packets in and packets out are normal |

Much easier to make sense of. I may start to link to that page from now on. "Freedom is just Chaos, with better lighting." Alan Dean Foster |

Thanx for the heads up. I'll compare the two next year and see what happens.... "Freedom is just Chaos, with better lighting." Alan Dean Foster |
