Good morning, it appears we have some work ahead of us. As many of you have pointed out, there appears to be a checkpointing bug on these work units. Please note that if you did encounter an invalid, you will still get normal credit for those during beta.
Thanks, -Uplinger |

The only invalid one was when I had to hibernate my laptop. I suspended activity before I did so, but apparently that wasn't good enough. The WU seemed to proceed normally but was inconclusive and then invalid when the third result came in.  |

Thanks. That explains why all my beta's that were swaping out with other project's wu's were invalid.

I have two wu’s running on a Pentium D that have run 12+ hours and are above 100% completion.
----------------------------------------BETA_erlc_a134_pe0000 @ 135.500% BETA_erlc_a107_pe0000 @ 108.050% Is this an expected condition? |

No it is not normal for them to be above 100%...Please try to find the slots directory they're in and copy the result.out file and he stderr.txt file to your desktop. the stderr.txt file may be a link to the projects/www.worldcommunitygrid.org folder. These are in your data folder.

Just to be sure I checked 4 tasks of 1 single machine (Linux64):
----------------------------------------1 valid (without restarting during the task). 2 invalids (the one 2 restarts and the other 1 restart during the job) -- Leave in memory was on. 1 Pending validation (without restart during the task; waiting for wingmen).  |

I'll try to get that info when I get back. Strange.  |

As Mathilde2006 pointed out in a recent note this can happen if a WU restarts from a checkpoint. First some 100+ percent value is shown until the next checkpoint is reached. Then the percentage is adjusted and jumps to the correct value. Coluld it be that your pentiums restarted the WU or did a project swap to WCG? I guess it takes some time for them to reach the next checkpoint...
I did not mention the unusual percentage value because I'm used to see such values from HCMD2... ;-) Matthias |

Ok, it appears Matthias is correct. When restoring from a checkpoint, you will see the percentage complete go up higher than expected. This is just an issue with the calculation of percentage complete...as noted, it is corrected and updated on next checkpoint, usually 5-15 minutes into the work unit.

OK, thanks for the information. Yes, both wu's were swaping with POEM wu's. Both have completed now. Odd though, although both were swaping; one is inconclusive and the other is pending validation.
----------------------------------------Looks like DDDT2 is not quite ready for "prime time" yet.   |
