LHC@home

Hi,
I have problems with all tasks, which use a VirtualBox after split Atlas@home and lhc. I tried to delete all project data remove projects, reinstall BOINC but the issue is still there. Before split I compute VirtualBox tasks normally, but now It ends with "Compute error". Mabybe should help if you change you settings of VirtualBox machines in system -> chipset to ICH9 (I cannot do that because session is locked) I have latest version of BOINC 7.6.33 x64 and VirtualBox 5.1.16 Thank you very much

For your ATLAS-tasks I found that you have setup it for 2 cores within the VM.
This is not well configured at the moment by the project.
It needs 4400MB of memory in stead of 4200MB.
Choose in your preference # of CPU's 1. This will take 2600MB of RAM.
Or alternatively use an app_config.xml and set the memory usage to 4400MB for a dual core.

Okay I try that, but I have the same problems with CMS, LHCb and ALICE tasks too.

Do you have VirtualBox Extension pack installed so you can monitor what's happening within the VM?

Yes I have the extension pack. If I click on show console of VM so in the VM terminal I see any "kernel panic not syncing fatal exception in interrupt " error

That's not good! It seems your VM is stuck for whatever reason. You could try to get it run by hand.
If you want that:
- suspend that task in BOINC with "Leave applications in memory" off.
- Disgard with VirtualBox Manager the saved state
- Start the VM with VirtualBox Manager (in fact a fresh boot)
- Look what's happening

When you have the impression that's running normal

- Shutdown the VM with save state chosen

.. and you can resume the task in BOINC

I'll try that and post results. Thanks for now.

So I tried everything, now I reinstalled BOINC and Virtualbox (both I uninstalled deleted all registry files and other waste) and make fresh install and now If I add LHC project so I didn't get any work :D :(

What is the answer in BOINC Event Log after requesting work.
Maybe you wasted the daily quota by returning many errors and/or aborts.
I think LHCb is not possible anymore for that machine today, but maybe Theory or ATLAS.
Set in your preferences Max # jobs to 1 and Max # CPUs also to 1.

I give up. I'll compute only sixtrack, maybe If I will have a free time so I look at that and try to solve :) Thank you very much for your ideas :)
