I hope everything works out as well Eric thanks for the update. Out of curiosity when everything is working as it should between Greenbank and Berkely are all of the tapes shown on the server status page transferred is one file or are they transferred individually (but all downloaded at the same time) Thanks in advance. I appreciate you taking the time to answer |

Related to Green Bank ... What did you find with the Slow splitting and deletion of GB data? AP & MB WU-awaiting-deletion are both climbing sharply. But at this stage they haven't impacted on the splitter output- Received-last-hour is still only around 115k, not the 130k+ it was with the much shorter running GBT WUs. Grant Darwin NT |

So based on the problem with Green Bank, my Dell will not download data but my iMac will. I sthis normal. Thanks for advising all if us. |

I don't see any problems with S.E.T.I. or B.O.I.N.C. on my computer. Everything appears to be running perfectly. But, I'm just a volunteer, and not a scientist, so I don't even know what it is that I'm looking at. John Robert Mallernee Ashley Valley Shadows Vernal, Utah 84078 |

I hope everything works out as well Eric thanks for the update. I believe Matt uses multiple parallel rsync connections, one from each of the compute nodes on the Greenbank side. So each file goes over a single connection, but separate files may go over separate connections. Each of the names listed on the status page actually consists of multiple files, each no larger than 4GB. @SETIEric@qoto.org (Mastodon) |

I hope everything works out as well Eric thanks for the update. Thank you for the answer. There is lots of compression which would certainly save on bandwidth when transferring files. |

I hope everything works out as well Eric thanks for the update. Maybe, maybe not. Random cosmic noise won't compress much. |

I hope everything works out as well Eric thanks for the update. Good point Gary. I originally misinterpreted what Eric had said. I misinterpreted that there are multiple files per file listed on the server status page. I read it as each tape was compressed down to no more than 4 GB from its original size of roughly 51/52 GB |

Related to Green Bank ... What did you find with the Slow splitting and deletion of GB data? Looking at the Haveland graphs, the I/O battle between Results returned-per-hour, WU deletion & Splitter output continues. Grant Darwin NT |

We see a lot of new tapes, was the problem finally fixed? |

We see a lot of new tapes, was the problem finally fixed? I suspect it's Matt & Eric burning the weekend midnight oil to keep the data flowing. Grant Darwin NT |

We see a lot of new tapes, was the problem finally fixed? That's about the slow splitter/file deletion issue, which is still occurring. Grant Darwin NT |

We see a lot of new tapes, was the problem finally fixed? . . That was a different issue .. it was about the apparent resources conflict between splitting and purging. . . It seems I am always too slow :) Stephen :( |

Sorry i was not clear in my question. I was asking about the slow network connection. If they finally fix that problem. |

I would think news of that importance would warrant a front page post saying the network issues between GBT and Berkeley had finally been resolved. The data mounted today is just Eric and Jeff working through the weekend to keep us happy with something to crunch.
