Dear participants, at the start of current search we set deadline for "CMDock long tasks" to 14 days or 336 hours. But average time required to process an individual task is 40 hours. Also, we see, that many of uncompleted tasks which prevent completion of the set to which they belong, "produced" by computers that catch some tasks and didn't get in touch again. Due this, we plan: 1. To perform a gradual reduction of the deadline; 2. To implement a simple mechanism which finds computers that are lost in computing space (those who did not send requests to the server in last m days), and mark its tasks as lost. For example, m may be 10, 8, 6 or 5. This should not interfere with computers actually participating in the calculations, but can be greatly enhance "results logistic". |

Not sure if you are aware it appears that "short tasks" are not being "sent out" even though there is short tasks ready to send. Have had no issues receiving the long tasks. As I write there are 1634 short tasks ready to send |

Hello! "Short tasks" for computers with ARM CPU only. But for single-board computers like Raspberry Pi they are also long. |

Thanks for information, that makes sense |

Hello! "Short tasks" for computers with ARM CPU only. But for single-board computers like Raspberry Pi they are also long. And the long ones are even longer for those! I am currently crunching on a Long Wu sind alsmost 17 days, and it will need 3 more days. But in my account it already timed out and got assigned to a new machine. Should I abort it? https://www.sidock.si/sidock/result.php?resultid=79849315 Best regards Felix |

Good point, somehow i missed this one. Thanks Felix |

Ah so that's why my ratio of compute for SiDock has been diverting compute from WCG. It used to be perhaps 33% going to Sidock, now maybe 45%, all points being equal. |
