I did look to see if there was somewhere else I could post this, but a new thread seemed most appropriate. I have had a validation error very early on ' any clues as to why: https://denis.usj.es/denisathome/result.php?resultid=522077 |

We detected this type of errors in the beta version and we reduced it from 5% to around 0.1%, but there still are some computers that have this problem. Most of the initial problems come from the checkpoint, but we are not sure if the small percentage that remains is still in this part of the code. I have not checked this in the last simulations yet, but in the beta version was caused by only a few Windows computers. We will keep trying to find the cause to reduce it to 0 (or as little as possible) Best, Jesús. Jesús Carro Universidad San Jorge @InSilicoHeart |

I may have found where the bug is... I'm testing it with the Beta version Jesús Carro Universidad San Jorge @InSilicoHeart |

Let's check the version 0.10... I just uploaded it recently, let's see if it solves the problem Jesús Carro Universidad San Jorge @InSilicoHeart |

Hi David. It is in our side. The difference is really small, with this information I will review what is happening to try to improve. We have very few invalid simulations, to find them help us a lot. Thank you a lot Best, Jesús. Jesús Carro Universidad San Jorge @InSilicoHeart |

Hi [Jean-]David. It is in our side. The difference is really small, with this information I will review what is happening to try to improve. We have very few invalid simulations, to find them help us a lot. Two more have failed (and 202 valid ones). So less than 1%. Do you want me to send more as they come up?

No, don't worry. I will check the code and later I will analyze the results of your tasks. Thank you. Jesús Carro Universidad San Jorge @InSilicoHeart |

I ran two Windows Updates recently, so my computer restarted twice. I'm looking at over 50 Validation Inconclusives, with 4 tasks already marked as Invalid. Otherwise my computer is reliable. So something is still wrong with checkpointing. The task resumes, but the answer is wrong. |

Hi Dayle, We have observed an small increment in the non valid results. We are analazying what is happening. Neverless, the percentage of non valid is still very small. More than checkpointing problems, it is related usually with problems opening or saving the file (which depends on the operative system). I will keep you updated. Best, Jesús.

Hello Jesús! Just in case it helps with your R&D: Like Dayle, my very reliable computer produced many invalid tasks, starting at 11th April: https://denis.usj.es/denisathome/results.php?hostid=224703&offset=0&show_names=0&state=5&appid= WU status as of now, filtered from this week's batch: 1050 all 16 invalid 23 inconclusive (86 pending validation) Also, a funky single WU with 3 invalid tasks from last week: https://denis.usj.es/denisathome/workunit.php?wuid=4312100 |

+1 I'm seeing about 1.25% invalid across my entire farm (6 systems). These are a mix of OSes (and OS levels) and processors. This is not normal for my group of machines. |

I now have 2,353 WUs pending validation and it is growing every hour. Is this normal? |

Most projects get to about 150 then stabilize around that point. This project reached close to 3000 pending before work ran out and it started declining. Not complaining, just curious as it seems like a lot of pending work. |
