https://www.cpdn.org/result.php?resultid=21827977 I am not sure that work unit will have valid results. As the Myth Busters used to say: "Failure is always an option!" |

Nothing wrong with that one. The computer could do with more memory though. |

Nothing wrong with that one. That container was set up with a profile that gave it 50% of the system's total RAM. I later changed it to have access to all 32GB. That ways a few days ago and I am not sure why the specs haven't updated on the web site. |

Nothing wrong with that one. As a result of requests from moderators, there have been a few changes to information on the website recently. Really to cope with all the Linux task types (including openifs which will appear at some point in the future) machines need to have 4GB/core in use. My desktop if running N216 tasks, I am limiting to one out of two cores but I think that is more a cache memory than a RAM issue. The openifs tasks in testing used over 5GB RAM/task but that was peak. several tasks at once OK on 4GB/core because they tend not to peak at once. |

Nothing wrong with that one. In a "worst case" scenario four or more threads peaking at the same time could cause my server to start swapping. It does more than just crunch. It is has 4 other full time "low CPU, low RAM, low I/O" tasks and one other full time "low CPU, variable RAM, variable I/O" task. So that makes me wonder how long these peaks might last and how much I/O they might need to sustain full speed calculation. I don't expect any answers at this point. I am just "typing out loud" as it were. The new tasks will be released on time, when ever that may be. For now there are still over 2000 N144 models and (at least from what I can guess) less than 100 of us working on them 24/7. |

Is there any plan to port openifs over to Windows as well, or will this be a Linux exclusive? Seems there sadly are not many Linux crunchers out there, or at least connected to this project in comparison to others. |

There's been no mention of OpenIFS since the big run back in June. Don't worry too much about the lack of Linux users. There's been very little work for us for most of the year, so when the current lot are gone, it may be well into next year before we get more. |

Seems there sadly are not many Linux crunchers out there, or at least connected to this project in comparison to others. I have been signed up for CPDN for ages, running only Linux. If memory serves, I went about a whole year without getting any CPDN work. Presently, I am running one hadam4h and two hadam4 work units. Also one WCG work unit. My normal intention is to run 50% CPDN, 25% WCG, and 12.5% each of Seti@home and rosetta@home. I enable these last two only when I have idle processor cores and cannot get either CPDN or WCG work units. When the latest hadam4 and hadam4h Linux units started coming out, I was running 100% CPDN for a while. I do not know if you would count me as a Linux cruncher during the year when I crunched no CPDN work units, because I did not get any. |

From what I remember reading on the openifs site, it is for Linux and Mac only so, major work to try and port it to Windows. A major advantage over the Met Office code is that it is open source. It is also 64bit so while it might exclude a few computers, it will not suffer from the missing libs issues. |
