Hello to every one,

I am encountering only errors since a few weeks, could anyone help ?

Thank you in advance !

Your error tasks are all ATLAS. The valids are all Theory tasks, so switch to only Theory (+evt. Sixtrack) in your preferences.

It seems your machine has enough memory available, but maybe BOINC is not allowed to use enough of that? ATLAS needs 6600 MB for a 4-core task.

Thanks for your response. For Months the Atlas and Theory were both working perfectly well. Indeed the most of the last tasks are from Atlas, but the last theory ones were failing too.

I have no idea why everything is failing. I wonder if it's linked Virtual box which generates the problem

Maybe you have to cleanup.
Don't request new LHC-work for which VBox is used.
When all tasks are gone, stop BOINC's client, open VirtualBox Manager and have a look in the File menu for Virtual Media manager.
Maybe you see there several virtual hard disks with an exclamation mark. Remove them all and try again with 1 Theory task.

Done that but my Virtual boxe is completely empty, there's no virtual machine on the left of the VBOX window, so nothing to erase.

Do you know how to add a machine ? because when I launch BOINC and keep watching on VBOX, there's no "new" virtual machine popping up, and I guess that's not normal

Nice day

Sorry to be pedantic, but did you already go over and verify Yeti's Checklist?
https://lhcathome.cern.ch/lhcathome/forum_thread.php?id=4161

It's really thorough and should catch most issues.

Are you using any customized preferences e.g. app_config?

BTW, concerning your previous question: yes, once Atlas is running tasks will finish with random percentages short of 100%. The way the Atlas is setup at the moment, each task contains 200 events to be simulated. Once those are completed, the task stops. You can also check what is going inside the VM as well as the current progress with Vbox Extensions - Yeti's Checklist will teach you how to do so. But we need to get Atlas running first!

You don't have to add a virtual machine yourself. BOINC is doing that for you. It tries that, but in you result:
VBoxManage.exe: error: The virtual machine 'boinc_b40b65bfe418f97a' has terminated unexpectedly during startup with exit code 1 (0x1). More details may be available in 'C:\ProgramData\BOINC\slots\0\boinc_b40b65bfe418f97a\Logs\VBoxHardening.log'

Since Theory was working well before, did you change something? Did you enable Hyper-V from Windows 10?

Try with Theory first and you could have a read here: https://lhcathome.cern.ch/lhcathome/forum_thread.php?id=4161&postid=29359

I've been having similar issues since I started up this project. Most notably with Theory Simulations and ATLAS. From a quick glance, a lot of it appears to be related with vbox, but I'm not going to pretend I know enough to really understand the cause of the issue. I've been able to see some success by forcing a vbox sim to run one at a time. Status typically ending with Error while computing. I'm seeing a fair amount of "unknown error code" in my exit status. A lot of these appear to end at a 20 second run time. These outputs are fairly long, so I'm not sure what section or all of it would be helpful in diagnosing the issue.

Welcome Andrew,
you have to enable in the prefs of LHC to show your Computer.
Should LHC@home show your computers on its web site?
