My guess is it failed on the first machine because of lack of memory. - 11GB RAM and 4 cores- it looks likely that the user is running all four cores at once which would explain a relatively high failure rate. Order came in and four modules installed, so I am less likely to run out of memory than ever before. OTOH, there are no CPDN tasks here, so none are running. My first hard drive, at work, held 40 Megabytes and spun at 2400 rpm. One or two decades later, I was amazed to have a 2 Gigabyte hard drive that spun at 7200 rpm. And now I have 125 GBytes of RAM! Amazing the progress from 1965 until now!

Send Personal Message to me if interested rather than reply here. If there is sufficient interest, I'll share the files on dropbox. I'll post answers to PM'd questions here. How do I do that? If you are still interested, I raised my RAM to 128 GBytes this afternoon. $ free -hw total used free shared buffers cache available Mem: 125Gi 5.8Gi 114Gi 82Mi 13Mi 5.2Gi 118Gi Swap: 15Gi 0B 15Gi ![]() |

Next OpenIFS batch about to go out today. Missing file fixed.#993 is now out there. My first one is about 6 minutes in so well past the time when the problem occurred. Edit: third zip has now been sent. |

I wonder if there is a problem with the tasks being uploaded. I have only got one, a request an hour later said, "project has no tasks available." That seems a bit quick for them all to go for Linux tasks. Well check again after next request. |

There were 188 unsent on the server status page at 12:45, and I got one of them at 13:01. It's running, but still in the early stages - I'll watch how it runs for a while, before switching into full multi-fetch mode. |

Mine seem to run fine, 40 Minutes running without a failure, zip-Files have been uploaded from Nr 0 to 5 Supporting BOINC, a great concept ! |

Yikes - there are 123 upload files in all, and the first one was over 15 MB. Your band is going to get very bored, Dave! |

That seems a bit quick for them all to go for Linux tasks. Well check again after next request.Maybe just getting there slowly. I have a second one downloading now and two is my limit without overloading my connection. (I could let five or six go via my phone which would be faster and still have enough headway for other usage. Edit: Estimate based on percentage completed rather than BOINC'S guess is just over 10 hours on my Ryzen7 |

That seems a bit quick for them all to go for Linux tasks. Well check again after next request. It's working fine. It just takes time to process all the tasks to be uploaded. They get taken up very quickly. --- CPDN Visiting Scientist |

The server status page has finally updated, and both 'Unsent' and 'In progress' have gone up substantially. Looks like the workunit generator is running at about twice the speed of our demand load, which is fine. |

Someone can have the retry for my first one of this batch: it got a "double free or corruption"... The system in use is a Ryzen 3700X with 32GB RAM, and it is only using about half that under the current load (including a second OIFS task it got when reporting this one.) I only run one CPDN task at a time. and none of the other BOINC stuff I'm currently running on that system (a maximum of 9 other processes) will get up to a single GB of RAM! I'll keep an eye on both this system and the other one that also has a single CPDN task in its BOINC mix (a Ryzen 5600H with 32GB RAM, currently showing about 24GB free...)... Cheers - Al. |

I have only got one, a request an hour later said, "project has no tasks available." That seems a bit quick for them all to go for Linux tasks. I have one running. Since I just doubled my RAM size to 128 GBytes, I diddled app_config.xml to run two at a time.

Someone can have the retry for my first one of this batch: it got a "double free or corruption"...This bug is bloody annoying. We've got a development version in testing that makes yet more changes to the memory handling in the code, which may/may not fix it but it'll clean the code up anyway. We didn't have time to use it for this batch, there will probably be some test batches going out after this one. The biggest problem is I can't reproduce it in standalone testing and catching one of these on my machine so I can see exactly where it went wrong is difficult. We are getting there, the error rate has dropped substantially. It's a priority to solve it. --- CPDN Visiting Scientist |

:-( My fastest and best working cruncher had got lastly the definitiv dead tasks, that all errored out and now it has a daily Quota of 1. :-( Supporting BOINC, a great concept ! |

:-(I had that. I created a new boinc client on the same machine, different port, and attached to cpdn. Works. --- CPDN Visiting Scientist |

My fastest and best working cruncher had got lastly the definitiv dead tasks, that all errored out and now it has a daily Quota of 1. :-( I am not going to do that. In the last 5 1/2 hours I have completed 38% of the work. So I will just wait it out. For one thing, It will be another day and if there are any tasks left, I would get one. And if this one completes before that, they may raise my limit to 4 or 5 (I forget just what they do, but it is something like that). ![]() |

This task failed with a divide by zero error. Presumably this is one of those cases where the physics of the model get out of control? |
