What with servers? Can't upload... |

What with servers? Can't upload... Been that way after the weekly ouage for the last 3 weeks, this one just seems worse than the last couple. And even if you can upload everything the most likely response for a request for work from the Scheduler is "Project has no taks available", "No tasks sent" or "Timeout reached". EDIT- and if you do happen to get some work, it's all shorties. So you'll process it faster than you can return it, let alone get new work. If that were possible. Grant Darwin NT |

No upload problems here. With each crime and every kindness we birth our future. |

No upload problems here. Consider yourself lucky then. ;) Cheers. |

120 downloads and 110+ uploads not moving even with an application of "retry" Have set NNT on all 3 machines, no point adding to the problems. |

120 downloads and 110+ uploads not moving even with an application of "retry" I expect to be out of CPU work on both systems when i get up in the morning not being here to hit retry endlessly overnight. And when i finally do clear the backlog, i can't get enough work to even top up the cache, it just keeps getting smaller. Have set NNT on all 3 machines, no point adding to the problems. Won't make any difference- all those backedup uploads will stop any Scheduler requests from occuring unless a WU is near it's deadline. Grant Darwin NT |

120 downloads and 110+ uploads not moving even with an application of "retry" Yes but if and when the log jam breaks I can report and upload without bothering to ask for more. |

No upload problems here. Yes seems Mike is the only one without any problems. |

Hi Its seems nearly certain the folks at SETI have no idea a problem exists. To expidite solution I have contacted a SETI sponsor (Planetary Society) with the aim of getting attention drawn to the situation ; "Hi I’m one of the many tens of thousands of people who contribute time and energy crunching data for SETI at home and work. For over a week there have been severe upload and download problems effecting every participant and the situation is becoming worse. People are running out of work and only a reduced number of the smallest work packages are being processed. No one from SETI has contacted anyone via the SETI forum or through announcement. There is a worrying silence and some of us think they have no idea a problem exists. There is no direct communication line to SETI for members so those who give a dam can do nothing at this time. I have contacted your organisation, as a sponsor of SETI, to ask if you have communication lines to SETI and then if so please use them to begin a handling for the current situation and also to provide some contact for the folks who are wondering where the situation is going. Many Thanks Des" |

Hardly Planetary Society can do anything... The only possibility is to pay for gigabyte ethernet link for SETI... Meantime cant' upload to SETI beta too :( |

Hardly Planetary Society can do anything... I contacted the PS because as they are SETI sponsors so they will have ability to contact SETI directly to alert them to the current problem. I dont think anyone in the forum has a direct line to SETI. D |

Hardly Planetary Society can do anything... I believe several people do indeed have ways of contacting the LAB, I have left a message with one and am waiting a reply. |

I dont think anyone in the forum has a direct line to SETI. I'm pretty sure a few people do, but I don't think that's the point. I'm guessing you're thinking Google Inc. when instead you should be thinking Google Garage Days:) But even THAT is not the point. Point is the last time I ran out of work to crunch was probably 18 months ago. And that was because the servers were shut down. Probably Feb. 2011? Anyway! If you find yourself running out of work on a laptop (which I see is your highest cruncher) then I'm sure we can help you get your settings and Boinc versions sorted out so it doesn't happen again. Just create a thread here in number crunching. Simple:) |

Hardly Planetary Society can do anything... You are incorrect. Anyone can contact the folks who run this SETI@Home (not simply SETI) project, directly, by Private Message, through their postings in these Forums. Many of the folks with "Volunteer Tester" and "Volunteer Developer" tags under their names also have direct email contacts with Eric and Matt and Jeff. They ARE aware of the problems with uploads, downloads, and scheduler requests. A BIG part of the problem is the bottleneck at the 100 MBs data link to the servers. This IS being worked, but as has been said repeatedly, the fix involves organisational politics at the University of California. Another big part of the problem is the "shortie storm" we have been going through the past 2-3 weeks. We ALWAYS have up/download problems during shortie storms, for the reasons given in other posts, but this is one of the longest storms I've seen, and because of the continuing improvement of the computing power of the participants, one of the most severe. This SETI@Home project does NOT recieve major funding from the Planetary Society (or any other pro-Space group), they are more involved with the SETI Institute and the Allen Telescope Array. This project gets much of its funding from donations from the participants. It operates on a shoe-string budget, and the staff are all part-time, sharing their time and efforts with other projects at the Space Studies Lab. Nothing happens quickly here, but as Bernie said, eventually it gets fixed. In the meantime, patience is not just a virtue, it is a requirement. Donald Infernal Optimist / Submariner, retired |

Last week I couldnt buy a download. This week I cant sell an upload. I havent seen this long of a shorty storm either. We will get work when we get it. [/quote] Old James |

Donald, whilst I do not doubt you. The tone of Matt's post yesterday did not suggest to me he was aware of any problems at all. Which again I agree is surprising as normally someone at the lab knows as soon, and sometimes before, we do. Unless of course this is just an overload of the system because everything IS working. |

Patience folks, patience. I'm working on a few new bits of hardware that will help out our downloads sticking issues. We should be launching these shortly I hope once I get the specs approved. There are several of us 'behind the scenes' types who also crunch and know what issues we're facing. We're trying to address and fix these as soon as possible but due to a lack of manpower in the lab, things are necessarily slow going. One piece of hardware I'm hoping to get will be a load balancer which will more evenly distribute tasks to our download and upload servers. Currently as people have noticed, you will ping off of a dead or overloaded server which constantly mucks up the works. In the near future I'm hoping we can implement a very beefy balancer with proper software and hardware which will alleviate this issue significantly. If you really want to help us fix these issues, keep reporting your performance and consider donating to the project in whatever capacity you're comfortable with. In short, patience. We've switched over one server's tasks (mostly) to George and have switched from Apache (which has caused us a load of issues) to Nginx. Add the time spent switching all of our processes over to a new switch, dealing with a crashy server and the push to V7, you can see where our small staff is overwhelmed. Our DL/UL issues will be sorted soon. Executive Director GPU Users Group Inc. - brad@gpuug.org |

Patience folks, patience. Great work on the download servers - they seem to be running much better today, with nginx. But what goes down, must come back up again, and is seems Bruno is having difficulty keeping up... 03-Oct-2012 16:23:35 [SETI@home] [http] [ID#45620] Info: Trying 208.68.240.16... |

Have you ever been a passenger in a car and noticed an ugly situation developing that you aren't sure the driver has seen? It's much, much easier to relax if the driver just mutters, "I see 'em." Thank you for reporting that the lab is aware. |
