We had the usual outage today which was mostly a success. The database compressed and was backed up in just over an hour. Normally this takes almost twice as long but the result table has significantly shrunk over the past two weeks (wonder why?). After that we put the new thumper in the closet (we being me, Eric, Jeff, and Kevin - it's a heavy machine). We also rebooted bruno to cleanly pick up a new disk (replacing a failed disk from yesterday). And I rebooted penguin to attach koloth's old tape drive to it (so it could read the classic data tapes for splitting). That all went well. We also updated all the BOINC-side code to bring the SETI@home project in line with the current BOINC source tree and a few things broke, namely our validators and assimilators. These aren't project critical for the time being, so we're postponing dealing with these until we deal with the real problem at hand: getting people to connect to our data servers. I think this is the longest outage we've ever had (even though it wasn't a "complete" outage - just no work was available) and we're in a whole new network configuration since the last major outage (new OS, new servers, new ISP, new switches, new router). In short, we're being clobbered by the returning flood of work requests. The major bottleneck is somewhere in the direction of our Hurricane router or bruno. Or at least that's the way it seems right now and there's no guarantee that when we break that dam a new bottleneck won't arise. I don't have the time to spell out what is broken and what we tried and what failed and what yielded unexpected results. Just know we're working on it and we understand most connections are being dropped. - Matt -- BOINC/SETI@home network/web/science/development person -- "Any idiot can have a good idea.

Thanks for the update, I think everyone realised that there would be a bottleneck somewhere. Proud Founder and member of Have a look at my WebCam |

I remember back in the early days of SETI/BOINC there was no weekly scheduled outage...With all the new equipment coming on line...Does that mean that back up day may become a thing of the past? PROUD TO BE TFFE! |

Is there a way to send the results? I don't care about the credits, but some of the results will expire tomorrow. |

Except I got some that expire today. Never surrender and never give up. In the darkest hour there is always hope. |

Totally understandable Matt. We know it will take a week or two for things to settle down again. We also know you guys will be doing all you can to ease the situation in the meantime, but you must be fighting a very uphill battle! I bet no one ever envisaged these levels of network traffic when they dreamed up SETI ;) *** My Guide to Compiling Optimised BOINC and SETI Clients *** *** Download Optimised BOINC and SETI Clients for Linux Here *** |

Boincers massing at the southern wall, sir. ;-) I've suspended Seti since the outage occurred, the fleet picked up on backup projects, at least until the logjam breaks. Our Team certainly ensured that backups projects were added, and gave everyone a quick lesson on how to ensure that they don't run out of work. I suspect many other BOINC projects benefited from increased resources the past week or two. Kudos for your team getting the project back online, the efforts are appreciated.

Don't worry about rushing, guys. She'll be up when she's up, and we'll be here then. |

I already have WUs that are behind deadline, and they look like they were downloaded after deadline. Of course, the outage is also affecting Beta. *sigh* Keep up the good work lads, we appreciate it! |

I already have WUs that are behind deadline, and they look like they were downloaded after deadline. Is my understanding correct though that units that exceed deadline will still be reissued, thus creating more download traffic (reissue) and more upload attempts once completed? If so, this is a snowball. |

It won't add or subtract from the network traffic. It will just be one more Work Unit available to crucnch amongst all the others that haven't yet been downloaded at all. Grant Darwin NT |

Isn't it possible to turn of the "due date" of the results until the connection problems is resolved. that way one result dont have to be sent out to more computers than neccesary.. Its just a waste of computing power in my eyes... |
