The fact that Matt has sent out a message saying that the outage has been cancelled indicates that the outage for the repairs to the SSL-wide power systems has been cancelled for this weekend, and that the whole of the SSL will be breathing a communal sigh of relief. One of two things has happened - the uni has not been able to undertake the repairs this weekend for whatever reason, or the uni has found a way to conduct the repairs without shutting down the whole of the SSL. I suspect the former is the more probable, so there will be a planned outage for the work to be done, and there will be notice of it being done so the whole lab can prepared for it.

Looks like there can be some outage on Monday, though. IST Service Status writes: Scheduled Outage Space Sciences Laboratory But perhaps that it only affects the forums, and not the data carrier. |

Looks like there can be some outage on Monday, though. Only half an hour allotted, and before normal working hours at Berkeley - should be minimal impact on us, probably just the forums and front page. Donald Infernal Optimist / Submariner, retired |

This is an ITS outage, not a power outage, and it only affects (one of) the out of building switches, so the servers will be able to carry on, but there may be no out of building connectivity depending on which switch they are working on and how that switch is being reconfigured.

I'm concern that they haven't powered down for the scheduled electrical work. I'm concerned because I could see that the staff was told the work was delayed but sometime today someone else will simply cut the power, leading to a mess that'll take days to restore. I take it you haven't worked with contractors, utilities or a university maintenance department before. It makes those 6 hour windows for the cable guy seem downright convenient. ;) Edit: Okay, they did canceled it. Now back to your previously scheduled grumblings already in progress.

Just now downloads are back to their normal - about as fast as a snail with arthritis moving across coarse glass paper... Unlike when there were 4,000,000 awaiting download when I couldn't get any, but downloads were fast. I just wonder if they were trying to see what happens if you overfill the tanks, and at what point the downloads "work well". Keep going down, its a long way below the current level.

Scheduler response times are still measured in seconds though, here at home at least. I wish they'd start to increase the limits a bit though, my faster machines can't last too long a break at 100 GPU WUs/machine. |

I notice this morning that my pc 6738288 has marked around 100 tasks as abandoned. What caused this and is there anything I need to do? It hasn't abandoned anymore in the past 6-7 hours and appears to be working. Boinc tasks is reporting about 200 tasks on the pc but the web site reports about 120. thanks...Frank |

Random task abandonment has been reported before. Nothing you can or need to do on your end. Just keep crunching, and if the servers pick up the problem, they might resend the missing tasks. If not, no worries, they'll get crunched by somebody sooner or later. "Freedom is just Chaos, with better lighting." Alan Dean Foster |

I think you need to abandon all the tasks on your PC by resetting the project. If BOINC has marked them as abandoned you will not get credit for them, nor will any results you return count. I would also reboot the PC as there may be some sort of problem with it. This happened to me three times in two days over Christmas, always with the same PC. Everytime it got 100 CPU tasks, a couple of hours later they would all be marked abandoned. In the end I suspended CPU processing until I could get back to work to reboot he system and check there was nothing wrong with the PC. It has been fine since. |

Looks like things are grinding to a halt again. Can't get any GPU d/ls because I have 2 AP tasks that have been stuck for several hours and retries don't help much as it quickly drops to under 1.0 kb then goes into retry status. I don't buy computers, I build them!! |

Whatever was causing the MB validators to get bogged down appears to have cleared- the backlog is now declining instead of growing. Also the AP work appears to have pretty much cleared, so hopefully the download traffic will settle down shortly. And whatever they did to the splitters after that last outage appears to have worked- i can't remember a time when the splitters were able to pump out 60 WU/s time after time, but now the Ready to send buffer is back down to normal levels, that's what they're doing. 50/s is the worst so far, for a quite a while there they were struggling to do 20/s.

The current round of sick download performance was happening before the APs started to move, so you can forget them as the culprit - the root cause is a very poorly though through and implemented download scheduling algorithm that can do nothing apart from cause problems.

If they have found another gremlin with its neck stuck in a bottle, the hIT men can have a smashing time with it, unless the Trainman says otherwize :( |
