Eh? I've had windows since a 286. What is your oldest computer?yep me too but some machines just won't handle it so I do what I have to do to get them crunching |

At the point I wrote that message, I was getting about 95% of my CPU tasks being seperation. I can't just keep aborting them, as obviously I'm not here overnight etc. And I don't use a huge buffer. I've put CPUs that have GPUs on the same machine into other projects.I think you should bring every single one of your cpu cores here RIGHT NOW to help clear them out!!I'd love to but the big CPUs have got GPUs running Separation. If I try to get Nbody for those CPUs, the server gives me CPU seperations! Which are tremendously slow compared to GPUs and utterly pointless. I really don't understand why we don't have more options in the server preferences. Einstein manages. I've asked here at LHC: https://lhcathome.cern.ch/lhcathome/forum_thread.php?id=5850 Someone who hasn't been banned from Einstein could ask in there, as they have very detailed options. |

Now getting the full 300 per GPU of seperation on asking, but I see the validation queue is huge again. |

Because nvidia gtx 1650 completes workunit in 6 minutes while ryzen 3 3100 would need a hour. |

I see, CPU separations vs. GPU separations. My original interpretation was that CPUs are worthless here. Thanks for the clarification. |

CPU's are NOT worthless here there are 2 types of tasks here and only one of them is for gpu's, the NBody tasks are cpu only while the Separation tasks ARE for both cpu's and gpu's and then as noted before the gpu's ARE faster when running these tasks. The Nbody tasks are multi-threaded tasks meaning they will use all available cpu cores that Boinc will give it unless you use an app_config.xml file to control it. |

I have 1011 WUs listed in "Tasks" 702 of these are listed as "validation inconclusive", mostly N-Body/mt (CPU), but some Separation (GPU) Is this others' experience at the moment? |

I have 1011 WUs listed in "Tasks"Even in normal times, you have to wait until your wingman has verified your tasks. At the moment the server is panting like mad with millions of work units in the database because somehow it generated 15,000,000 instead of 10,000. Boinc is not the brightest of programs, on your end or theirs. |

Oh no not again..... I saw this over at Number Fields post Pentathlon: "I had to disable the "accelerated retries" mechanism due to all the abortions. When things stabilize I will turn that back on. This means reissued WUs will have their deadline halved." So there IS a way to get the Server to use shorter deadlines for the resends, I'll bet if Tom would talk to: Eric Driver Project administrator Project developer Project tester Project scientist He would help Tom figure it out as he's the one who made the above quote. |

I have 1011 WUs listed in "Tasks" Ah, thanks, maybe I was confusing "Validation inconclusive" with "validation pending". (edit) No, it seems that "validation pending" is a separate category, so I have 0 of those, and 702 "Completed, validation inconclusive" I am not concerned about credit etc., but 70% of WUs seems a high proportion to waste. |

I have 1011 WUs listed in "Tasks" They are not "wasted" they are just outside the expected range, every task has a sorta kinda thing they are looking for and when your task is outside that 'range' then they will send it out to someone else to crunch to confirm if the problem is on your end or the projects or even with the task itself. That's what all these numbers mean in every task: max # of error/total/success tasks 2, 9, 6. |

I saw this over at Number Fields post Pentathlon:Indeed, many projects do this. I often see shorter deadlines on retries. |

I really don't understand why we don't have more options in the server preferences. Einstein manages. If anyone wishes to run just the GPU separation WUs and n-body on their CPUs, send me the contents of your client_state.xml in a PM. I'll create a an app_info.xml that will make it work. I have a version already for nvidia GPUs on linux but not Windows. I need the info from the client_state.xml to see what the program filenames and other info. Maybe the app_info.xml files are already available in another forum thread. Don't know |

Isn't app_info.xml meant for anonymous platform mechanism setups? If it can be used in the standard setup, wouldn't you have to update the app_info.xml when the project updates its apps or if your system changes? |

Yes, if the project updates their app, the app_info.xml will need to be updated. Just offering an option to run just the separation GPU WUs and n-body CPU WUs on the same client without getting separation CPU WUs |

I would like to do that but am on travel all week. Will try to PM you on Sunday. Thanks for the offer. That is exactly what I want to do.I think you should bring every single one of your cpu cores here RIGHT NOW to help clear them out!!I'd love to but the big CPUs have got GPUs running Separation.

I was also able to create a working app_info.xml but for Windows. If anyone is interesting in trying it this way read the following BOINC page: https://boinc.berkeley.edu/wiki/Anonymous_platform to see what app_info.xml is and what it's meant to be used for as well as info on how to create one. I'd suggest draining your MilkyWay cache and setting the cache settings to absolute minimums before messing with app_info as it can cause unwanted consequences if mistakes in app_info are made during the process. This is not a set it and forget it option and will require some maintenance over time. Whenever the project apps, BOINC, or your system change the corresponding entries in app_info file will have to be updated manually. If your system is Linux app_info.xml is probably the only way to exclude Separation CPU tasks (and only get N-Body). If it's Windows 10 or 11 another option is to use WSL2, which is what I do and may go back to doing after checking how this works out since I use WSL2 to run other BOINC projects that either require or run better on Linux. |

Hey Tom, Now that the n body units are totally flushed(so to speak!), what are your plans? Will there be more n body in the future? Or is it totally done? Does your team need a few months to digest the data before committing to new runs? |
