Posted 17 Dec 2021 by PHILIPPE Post: For linux users , it is advised to download Boinc through the distro repository of their own distro. It is more secure. Don't use neither the boinc installer of the boinc site , nor the personal package archive (ppa) costamagnagianfranco-ppa. Thus , you will avoid incompatibility between the boinc code and the libraries needed. The drawback is that you will crunch with a lower or equal version than the latest displayed on the boinc site . But more important is that the behavior of boinc is correct to not discourage users. So , unistall boinc and follow this piece of advice to install it once again. Give us feedback to inform us of the success or the fail of this process. |

Posted 15 Nov 2021 by PHILIPPE Post: Apparently , raddoc has tested my advice and we can see a difference in the behavior of the results : 8890967 2952723 11 Nov 2021, 9:51:58 UTC 11 Nov 2021, 14:52:18 UTC Terminé, validation peu concluante 7,270.51 7,192.05 en attente NWChem v0.11 (vbox64_t1) From 6.0.14 ,He downgraded to 5.2.38 and a real change appeared. He has an amd ryzen processor :AMD Ryzen 9 5900HS Mine is an amd a10. So maybe the amd processors are more sensible than the intel processors for this project. |

Posted 8 Nov 2021 by PHILIPPE Post: It depends on the hardware , i suppose. I have no good results with my host with 6.xx.xx. virtualbox version. It is curious but this is the truth. This is why i advised him to try this change and downgrade .So , he may see the difference and would probably obtain more good results. It is just a piece of advice , if he wants to earn some credits with this project (gridcoin is his team). |

Posted 7 Nov 2021 by PHILIPPE Post: I sent a private message to raddoc , advising him to downgrade virtualbox to 5.2.xx version , in order to see if a change in the behavior of the work units occurs. But he didn't answer for the moment. |

Posted 4 Nov 2021 by PHILIPPE Post: To check a virtualbox work unit :
Click on button "properties" , and notice the " time elapsed" value and the " run time" value in the pop-up windows.

Validate error- Work Unit
(Message 1355)
Posted 15 Feb 2021 by PHILIPPE Post: This project explores the space of possible molecules generated. Sometimes , these molecules are either not possible , or unstable. To be validated numerically , these molecules have to be confirmed by two different computers over ten trials ( if necessary ). In your case , this work unit failed the test : no similar results , so no validation. It's frustrating but this is the rule. Only positive scientific outputs are rewarded ( even if a negative result teaches the limit of the exploration). |

(Message 1349)
Posted 13 Feb 2021 by PHILIPPE Post: This project doesn't require linux or a vm linux. It is possible to run it with only Windows and VirtualBox. You just have to enable virtualization in your bios and disable hyperV. Sometimes , the virtualbox version , has to be modified , to run properly on the host ( 5.2.X. seems to be better than 6.0.X.).It depends on your host. All the apps possible are listed here. You just have to know that with windows the wus are less stable than with linux.You have to handle them carefully at the beginning and at the ending of your computer , to avoid the misfortune... |

Posted 12 Feb 2021 by PHILIPPE Post: It 's curious : your two tasks , validated by the system , appear to be a multicore work unit (precisely 6 cores). 6010639 2313002 12 Feb 2021, 0:55:46 UTC 12 Feb 2021, 1:06:48 UTC Terminé et validé 662.00 3,972.00 200.00 NWChem v0.11 (vbox64_t1) 662 * 6 = 3972 seconds whereas the work unit is listed as a single core app :vbox64_t1 For windows hosts , there is no multi-cores work unit in this project. |

Posted 1 Jan 2021 by PHILIPPE Post: Thanks for the feedback. We know now for sure how to respond to people who encounter these types of errors: Only use the version of boinc software that is present and built by the maintainers of the linux distribution they run. It avoids incompatibilities between the libraries present and the dependencies necessary for it to work properly. Fortunately ,skill grows up with experience... But this project requires constant vigilance on the part of everyone to ensure that it runs smoothly... By the way ,Happy new year 2021, everybody !!! |

(Message 1286)
Posted 23 Dec 2020 by PHILIPPE Post: Thanks for the feedback , Jim1348. It is christmas , before the date.  I have found a post of Jord in the boinc forum ,he speaks about a change in the way , the user has to download Boinc.It was the 29 November. People that want to crunch on Linux have to go their software repository instead of downloading the latest version here. So, for linux and probably mac users , it is advised to download Boinc through their distro repository. It is more secure. Don't use neither the boinc installer of the boinc site , nor the personal package archive (ppa) costamagnagianfranco-ppa. Thus , you will avoid incompatibility between the boinc code and the libraries needed. The drawback is that you will crunch with a lower or equal version than the latest displayed on the boinc site . But more important is that the behavior of boinc is correct to not discourage users. Happy Christmas , everyone !!! |

Posted 18 Dec 2020 by PHILIPPE Post: I hope Damotbe can delete all the wus processed by him , and make the server goes on normally. So our work is not wasted. But the most important is to set the server to send wus to different persons.(security and reliability reasons).To avoid same situation. |

Posted 18 Dec 2020 by PHILIPPE Post: Looking at my last workunit , i see all the other wus , crunched by my wingmen are faulty. Curiously all the computers belongs to the same person , so all my wingmen are the same man. 272 274 275 276 277 279 280 283 1826 How is it possible ? I'm sure the wu is valid. Stop him , or it won' t keep any wus soon. |

Posted 18 Dec 2020 by PHILIPPE Post: I notice some computers in your list are the same. I think ,the owners of some computers faulty retryed to access to Quchempedia project , several times. If we take care of the features , these different id computers seem to be identical : (1003<->1007) (1008<->1967) (3713<->4443<->5132) (3733<->4790<->5306) (4505<->4796) |
