Junior halfroid is a cuckoo's egg I've had a number of work units labelled 'junior halfroid ...'. They look innocent enough to begin with, just like any other job. But when they get to the 90%+ complete, they seem to want more and more time. (Sounds like IT projects I used to work on.) Then this morning I found that a whole partition had been filled up with boinc/rosetta stuff. I am now aborting any junior halfroid work as soon as I see it. Has anyone else noticed this problem? |

What did you see that was filled? Disk space? How much space was consumed by how many active tasks? Don't put too much stock in estimated runtime to completion. The best predictor of your completion time is the runtime preference you have set in your Rosetta profile for the venue of the machine. There are several posts about how and why runtime estimates are wrong, and the issues BOINC Manager has where it requests more work than can be completed within the 3 days deadlines. See the Number Crunching board. Rosetta Moderator: Mod.Sense |

It was the partition that contained /var which filled up. I deleted the offending file without making a note of its name and reinstalled boinc, which has got things running again. At the moment one processor is idle and I have not worked out why. Perhaps it is just waiting for more work. |

I'm now attempting to run Junior Halfroid design 5 jobs, but I am getting very long run times - often over 24 hours. I have more memory on order - upgrade my laptop from 4 to 16 GB, and an SD card for my smartphone - and this might help a bit. |

There is one Task that you aborted after 3hrs 10min, one that ran for 19hrs 40min & then errored out, another that ran for 8hrs 40min & finished OK. And 2 systems where work has been down loaded & never returned. The system that did return a Valid Task & the other errored out shows signs of heavy CPU use other than Rosetta; a large difference between CPU time & Runtime. The default Target CPU Runtime is 8 hours, but Tasks can run for up to another 10 hours before the Watchdog timer will end them. Actual Runtime for a heavily used system will be much longer than the CPU time, which one of your systems is showing signs of. Grant Darwin NT |

Runtime is based on CPU time, not elapsed time. So, if the task is running along with other work, it may take longer to get all of the CPU time. Yes, these recent WUs are using more memory than is common. This may be slowing their progress on your machine as well. You can adjust the target runtime if needed, keeping in mind that the watchdog now takes 10 hours after that runtime preference to step in and end the WU. Rosetta Moderator: Mod.Sense |
