LHC@home

After a long time I started to elaborate some WU but I see that nothing has changed. The processing was supposed to last about 2 hours but instead it is lasting more than 24 and now it has been 100% for about 12 hours. Some advice?

So far there are no logfiles that can be checked.
If you have installed the VirtualBox Extension Pack you can
- open your BOINC Manager
- select an ATLAS task
- in the left column click on "show the VM console"

This opens a window that shows the VM's screens.
Press "ALT + F2" or "ALT + F3" to switch to "ATLAS Event Monitoring" or the VM's top output.


BOINC's runtime estimation is useless in case of LHC VMs since the BOINC client can't directly look into the VM.
ATLAS sends out tasks with shorter or longer runtimes depending on the physics that has to be calculated.
Single events can have runtimes between a few seconds and 1/2 hour and each task calculates 200 of them.

Thanks for the information.

8-core setups are known to be inefficient.
If enough RAM is available the #core setup should be limited to 4 or less.
