VirtualBox VM error
(Message 38742)
Posted 8 May 2019 by David Lambert Post: What does it mean when the Virtual machine in Virtual Box displays the following; "FATAL: Could not read from the boot medium. System halted." message? See the following screenshot; https://1drv.ms/u/s!AuUw84o3Xy6RjZIVV4ksiPWiLjP2IA Work unit is from LHC@home (Atlas Simulation 1.01 (vbox64_mt_mcore_atlas) |

Task(s) complete, but...
(Message 36655)
Posted 6 Sep 2018 by David Lambert Post: I have two tasks running on BOINC 7.12.1, both showing 100% complete, but one is still running and the other doesn't upload to LH/c@home. It remains in the que. Can anyone explain this behaviour? https://1drv.ms/b/s!AuUw84o3Xy6Ri44Zm6COAvCMPJ1Yhw (*.pdf) or https://1drv.ms/u/s!AuUw84o3Xy6Ri48dVExnjqYi2_SrTA (*.png) Microsoft Windows 10 Pro Gigabyte Technology Co., Ltd.

Posted 23 Jul 2018 by David Lambert Post: My LHC@home preferences are not updating as they should. I've been having issues with ATLAS tasks and have deselected that project in my preferences but the tasks are still downloading to my computer. |

LHC multi-core WU take a very long time.
(Message 35844)
Posted 10 Jul 2018 by David Lambert Post: Whenever an ATLAS multi-core WU runs, it takes a very long time to process. The current WU elapsed time is 2d 09:44:43 and shows 01:10:11 estimated time remaining. Properties for the WU show that it is processing 1.800% per hour. However, the properties for the WU also show that it has used 5d 18:26:06 CPU time. This makes no sense to me. Can someone explain the discrepancy? So, that would mean disabling all other projects in my preferences, correct? I can't remember the last time I saw something other than ATLAS run even though I allow all projects. |

Merging of computers
(Message 34964)
Posted 12 Apr 2018 by David Lambert Post: I'm a little confused about why old computers would not be able to merge with newer ones despite the differences in CPU's or OS. Do the results from older computers still show on the User Total credits even though they are no longer active? |
