do you think the server will be back today? Sarah who set up shifting the data to make space hopes that the transfer will be complete or enough moved to let uploads resume. She has been travelling to a meeting and is hoping to log in remotely to see if things can resume. Afraid I don't think anyone can say more than that but by the end of the day, we should if remote login successful have a bit more information. However when I think of how long it takes my system to back up 250GB worth of data and remember that this is hundreds of Terrabytes............. |

but you cant compare your system with theis system ;) i think they can use a big bandwith, at least 10 gbit i think |

but you cant compare your system with theis system ;) I was comparing it with a system a lot bigger and faster than my own, (biggest disk on system 20TB) but still small beer compared with what CPDN are dealing with. |

i just uploaded my first zip file, server seems to be back online, upload finished succesfully Edit: after ten minutes of uploading files, the connection to the server slows down realy fast. i think other users start to upload their zips too. hopefully the server won't crash |

Yes, it's been re-enabled, so go for it. |

but you cant compare your system with theis system ;) My system came with a PCIE two-channel 10 Gbit/sec NIC. I have unplugged it because I have nothing that fast to use it with. Its main chip has a big heat sink on it with a little fan to blow cooling air over the heat sink. Its other chip also has a big heat sink on it, but no fan. My Internet connection will do 75 Megabit/sec if the server at the other end will do it; few do. |

Two hadcm3s zips of 107MB just succeeded but restart needed two attempts. Out.zip also gone now. Expect transient upload errors until the servers stop getting hammered. |

It seems it even worked after all that. But I did not get any more credit than one of the other users who died from an Error while computing message.

Finally, after many failures and back offs my zip are slowly uploading. I know the server must be getting really hammered, what with 5 day of backlog to get through. If my relatively slow computers built up 33 zips in the time the fast 3.5GHz machine must have created a lot more. |

the fast 3.5GHz machine must have created a lot more. My slow laptop had over 2.5GB of files to upload. There are quite a few fast machines with 20+ cores out there crunching away. And I notice that the number of computers with recent credit is now up above 12,000. I suspect the next batch of work will fly of the shelves very quickly. |
