Uploading files fails
(Message 62496)
Posted 25 May 2020 by JIM Post: I am uploading two zips now. They are a bit slow at 50 kbps, but at least going. Did they ever finish uploading and clear? Many of mine have reached 100% only to stall there and then drop back to 0%. |

Posted 22 May 2020 by JIM Post: [ I assume that they are being done on laptops, which is the wrong place to do them I believe. I STRONGLY DISAGREE! I have been running CPDN (almost exclusively) for more than 10 years, since the days of the BBC experiment. I have over 20,000,000 credits. All of this work has been run exclusively on laptops. |

Posted 21 May 2020 by JIM Post: I see what you mean. I just checked my RAC and after about 4 months of no work for Windows my RAC is down to 6.3. I hope they fix this before all the Windows people lose the right to post on this site. |

"No tasks sent"
(Message 62418)
Posted 10 May 2020 by JIM Post: There are no Windows tasks (wah2) at the moment, and none on the horizon that anyone knows about. There should be some way to better spread these small test batches (if that’s what this micro-batch was) around so that they don’t all get sucked into this kind of black hole machine. Otherwise this will become more and more of a problem as processors get ever larger numbers of cores. |

What is "HadAM4 at N216 resolution v8.52"?
(Message 62321)
Posted 20 Apr 2020 by JIM Post: This is apparently the current work unit, and the last one I ran, but don't see a description for it. HadAM4 at N216 resolution v8.52 is the new Linux only model. From what I’ve read it requires a lot of RAM (about 4GB per core) to run well. |

Posted 14 Apr 2020 by JIM Post: And someone has returned a WAH2RI task" How long is it since any of them were sent out??? Most likely someone reactivated a very old computer that had been sitting in storage for a few years. I supposed it would be possible to pull up the trickles and see if there is a 3+ year gap between 2 of them. |

Posted 13 Apr 2020 by JIM Post: Just done my daily check of the status page. Number of users in last 24 hours shows Linux only three behind the windows tasks despite the, "number of tasks in progress" for Windows being about seven times as many as for Linux. I am guessing it must mean a lot of those windows tasks are never going to be returned. I’ve known that for years. Most of those “in progress” tasks have been lost in ways that the server never found out about and will never be completed. With no significant new work for Windows in months just about everyone with running Windows tasks has finished them. |

Posted 24 Jan 2020 by JIM Post: Will likely be gone fast. Its starting to look like the researchers have overreached what the average home computer can handle. There don’t seem to be that many home boxes that are running Linux and can meet the huge memory and L2 requirement out there as they expected. So they Linux work sits and sits. Meantime for Windows users the cupboard is usually bare. Keep this up and they could kill this project. |

Scheduler request too recent
(Message 61887)
Posted 3 Jan 2020 by JIM Post: Though I am not versed in the specific history, I feel like this project's deadlines were likely founded back when numbered Pentium processors (pentium 3, pentium 4) were in use and the amount of time to complete a single workunit took months for a single machine to complete, even when on 24/7. Your absolutely right. I was running this project back then on a single core laptop with a 1.2GHz processor with 256Kb of RAM. That right ¼ of a GB of RAM. The swap files got a lot of use. That was about 12 or 13 years ago. It took 8 or 9 months to finish a single 160 year WU. |

(Message 61751)
Posted 20 Dec 2019 by JIM Post: That has been tried several times, but it doesn't provide viable science. Maybe, considering the extremely small amount of Windows work available they should find a way to limit the number of cores that these 32 and 64 core processors can download a one time. There is no reason to allow these machines to hog all the available WU’s. I think 8 WU’s per machine at a time would be a reasonable limit. |
