Should the Extreme generation, say x, of your targeted workunit inadvertently have more than 5 workunits and generations x-1 and x+1 contain 5 or less workunits, then posting your workunit from generation x is also allowed. Adri, When I posted, the latest figures for generations 107, 108 and 109 were 1, 7 and 2 respectively, so I am happy to conclude that my post falls within the "relaxed" rule. Phew!  Interestingly, according to your excellent table linked in your original post in this thread, generation 108 now has only 3 workunits in it, so if I'd waited a bit before posting, I would have fallen within the "strict" rule. Cheers, Mark Indeed, Mark, The "History of the number of workunits within each generation" seems a valuable source to look back chronologically at the number of workunits in each generation. In the table, I've allocated three characters for the number of workunits (num) in a generation (gen); so a maximum of 999 workunits can exactly be represented in a column, a multiple of 1000 can be represented by 1k, 2k, 3k etc., other numbers between 1k and 10k will be represented by >1k, >2k, >3k etc., and numbers greater than 10k are being represented solely by 10k, 11k, 12k etc., e.g.: gen num|gen num|gen num|gen num|gen num|gen num NB: An important (older) part of it was made possible thanks to the big help of our friend Al.

Once a quorum has been reached, WCG should abort any outstanding units which have not reached the first checkpoint (12.5%). 12 minutes is not enough time to get to the first checkpoint. Mike |

ARP1_0033555_110_x seems to be a very difficult task. It has been running about 32 hours and only 85% completed (about 2.5% per hour). There 8 other ARP1 tasks running on the same machine and they are running normally (almost 5% per hour). I seem to remember Kevin mentioning that there were tasks that were more difficult either due to weather conditions being modeled or geography or both. Please check the TimeStep on this unit. If it has shortened then that would explain the longer calculation time. Mike |

Mike I don't think that is correct. Usually once a work unit starts it's outside the server's control. The server doesn't know when the checkpoints are taken as they are done by the app. ARP1_0033555_110_3 is still is progress as I write this and was issued at 18:46:31 UTC yesterday (that's almost a day a ago). I'm sure it has reached a checkpoint by now. ARP1_0033555_110_4 was server aborted probably becuase it hadn't started execution yet. Both work units were issued at the same time. |

It seems like maybe 104 and 106 might be stuck. Haven't seen any completed WUs in 2 days. 107 might be stuck too.
