I am in the middle of crunching my first result: http://www.ps3grid.net/PS3GRID/result.php?resultid=6002 I went to bed last night, and it was a little over 50% complete, on track to be complete just over 22 hours. That matches what I have seen with other results. I expected to see it completed by the next time I looked. This morning, I check in on it, and it shows 25:40 elapsed time, 53% complete, and 20 more hours to go. Is this normal? Or do I have a problem? Reno, NV Team: SETI.USA |

Now that I confirmed we have checkpointing, I decided to reboot to see what happens with this result. It now shows as 11:50 elapsed time, 53% complete, and just over 13 hours left to go. If I look at the elapsed time, and the percentage, it looks like it will complete in about 22 hours, which is normal, I think. But this thing has been running for over a day now. Opinions? Comments? Suggestions? Reno, NV Team: SETI.USA |

Okay, that WU finally completed and returned successfully. Here is the result if anyone wants to look at it (I listed the wrong one in the the original post): http://www.ps3grid.net/PS3GRID/result.php?resultid=6000 It says that it ran for 80261.98 seconds, or 22.3 hours. In reality, it ran for about 36 hours. Now there is a second oddity with my second WU. It has been crunching for about 20 minutes now, but the numbers are funny: 00:20:00 elapsed time 50.625% complete 08:42:29 remaining time Do WUs always take about 80k seconds? Or could this one really be shorter? Reno, NV Team: SETI.USA |

Okay, that WU finally completed and returned successfully. Here is the result if anyone wants to look at it (I listed the wrong one in the the original post): The workunit progression number does not work for restarted workunits. We still have to fix this. Only time is reliable. I does not seem there was a problem with your previous workunit. Let\'s see if it happens again. |

Thr run time should always be 22hrs and a few minutes minutes, of CPU time. If you have other stuff running, especially a screensaver, this takes CPU time too. The run time of the work will still be 22 CPU hours, but wall time will be longer. If yours took 36 wall clock hours, you have something else slowing things down. Look at my account and my system, you will see the run times are realativly all close. They vary by a few minutes. |

The second result took just over 80k seconds, both in wall clock and CPU clock. I noticed that the Time setting on the PS3 was *way* off. I am guessing that something screwy happened during the first result that caused both the delay in crunching and the Time to change. In any case, it seems a-ok now. Reno, NV Team: SETI.USA |

Right now, a WU has been running for 1.5 days and will soon complete. Did notice when I checked the TV that the mouse had been bumped and the view was in desktop 1,0 instead of the normal 0,0. Maybe this put the BOINC task in the background? |
