As a small update for folks waiting on AP tasks: Marvin's AP array ran out of disk space. Jeff and Eric have swapped out Marvin's 750G drives for some of the donated GPUUG 2TB drives (our spares pool) to fix the issue. Not sure when we'll see more AP tasks, but at least we know where the bork was. ![]() Executive Director GPU Users Group Inc. - brad@gpuug.org |

Thanks Brad for the heads up on the AP issue. Lookin' forward to the reemergence. |

Quick bit of news: 1. A check for $2000 from our SETI Direct donations was delivered to S&H on Thursday. I'm always proud to be able to cut such nice checks to the organization thanks to our donors. 2. We had a member donate today a 3TB hard drive to the project. Newegg was running a special so instead of our listed price, the drives are on special for $119. As a result I used some of our general funds to purchase 2 instead of the one paid for drive which will give SETI QTY 2, 3TB drives with which to use for AP Reob data. You can track this purchase by visiting http://www.gpuug.org/catalog That's all I have for now. We're still waiting on specs from the lab before starting our projects. ![]() Executive Director GPU Users Group Inc. - brad@gpuug.org |

And another 2 3TB drives donated by A.J. Ordered today, should ship all 4 drives out on Monday. I'll update http://www.gpuug.org/purchases with tracking once I receive it from Newegg. Our donors are awesome. ![]() Executive Director GPU Users Group Inc. - brad@gpuug.org |

Project Update: Marvin was fitted with a new RAID 10 using 8 of our donated 2TB Seagate drives. According to Eric these drives were 'really clean, no reallocated sectors on any of them.' This makes us think Seagate has gotten past its first of the year QC issues and is now shipping proper hardware again. This also means AP should be back up and running like normal. Lastly our 4 donated 3TB drives should hit the Lab tomorrow. Thanks everyone. ![]() Executive Director GPU Users Group Inc. - brad@gpuug.org |

New big project coming as soon as we tie up things on the GPUUG end. More in the coming days, stay tuned! I can only hope it sorts out the Scheduler issue. Then of course we'll need to get he bandwidth problem sorted. Then of course we'll find another bottleneck... Grant Darwin NT |

New big project coming as soon as we tie up things on the GPUUG end. More in the coming days, stay tuned! I agree, It seems maybe we are throwing hardware at UC Berkley being stubborn about a bandwidth problem. I will donate what I can, But id like to hear some news on whats going on to. ![]() Old James |

There was mention in a previous post by Slavac about getting a hardware load balancer, so that may help things a bit. My understanding was the project staff are trying to get the v7 app out the door. This would take longer to process and therefore reduce the work requests on the the server, at least until hardware and software improvements negate the extra processing time. BOINC blog |

Agreed it won't help the scheduler, but should help the download server "balancing". @Slavac, any news on the load balancer mentioned previously? Haven't seen a fund-raiser for it specifically.

What is the new science in the v7 app that would make the wu take longer to process? |

Its searching for another type of signal called autoCorrelation. With each crime and every kindness we birth our future. |

IIRC autocorrelation is a noise filtering technique, that should enable us to detect weaker signals hidden in the background. |

There was mention in a previous post by Slavac about getting a hardware load balancer, so that may help things a bit. Right now the plan is to wait on the load balancer after much discussion with the lab. The current plan (in order of likely priority which is subject to change) 1. Compute Node for the GBT. This will be a part of the high speed spectrometer. 1. A new upload server and download server. (Tossup as to priority with above. We're still chewing this one over with the lab) 2. Media converters for the lab. These will necessarily be funded, installed and tested before we reevaluate the load balancer. The hopes here are that the converters increase the much needed internal bandwidth of the project. My plan right now is to attempt to get the balancer donated by the manuf. vs fundraising but again this is dependent on sorting out the media converters above. We'll likely slot the converters into priority 1 status once the specs from SSL come in. ______ As far as news on what's wrong with the project currently I'm sadly in the dark. Also I should note we had another 3TB transport drive donated today which I'll get ordered this week. Lastly I hope to start a new project this week, likely one of the above large ones. I'll follow that up with a new thread with the relevant data, specs and so on. Thanks all. ![]() Executive Director GPU Users Group Inc. - brad@gpuug.org |

New big project coming as soon as we tie up things on the GPUUG end. More in the coming days, stay tuned! Bandwidth is something we're trying to work on (GPUUG - Lab - UCB) though the process is quite Sysyphean. I wish I could throw donor money at the problem and solve it but sadly that's out of my hands unless we do something creative (and expensive). I'll ask Eric and or Jeff to let us know what's up in a tech news post. Keep in mind that Dan's in China working on a very sexy SETI project and Matt's entertaining the world, so the lab's quite understaffed and slammed with these issues we've been fighting. ![]() Executive Director GPU Users Group Inc. - brad@gpuug.org |

I wish I could throw donor money at the problem and solve it but sadly that's out of my hands unless we do something creative (and expensive). One way would be to get something like an ISP to donate bandwidth. We can't get that bandwidth to the lab, but we could place a proxy/workunit storage at the ISP. I'm not sure the BOINC back-end could handle that. But if it could we could essentially halve the labs bandwidth requirement since we would only have to transfer an individual workunit once. |
