Development for LHC@home

A new app version (CMS v46.23) for Linux and Windows has been provided. It contains vboxwrapper v26183 which provides a heartbeat mechanisms that can detect if the VM fails to boot or freezes. It should prevent VMs just sitting idle if such scenarios as a kernel panic occurs at boot. A Mac version will be made available once a build is available. As usual, please let us know if there are any issues with this release.

Windows version crashed after 11 minutes run time cause VM Heartbeat file specified, but missing.

2nd task error too: http://boincai05.cern.ch/CMS-dev/result.php?resultid=112869

btw: Mac version is also available since 2 days.

Great, it looks like the mechanism is working. The heartbeat file is missing as CVMFS has still not updated. Should be there shortly. I will let Rom know and release the Mac version.

Will you inform us when the filesystem is updated. FTTB I'll run the new wrapper without heartbeat check.

Yes, it should be there soon. I will be offline for an hour or so will check when I can.

The updated file has arrived at CERN's /cvmfs so it's in the pipeline...
...and now it's on my VM (1643 UTC).

Using "Show VM Console" starts OK, but after some seconds and switching between screens leads to fault and then crash of the app and Computation Error.

Hi Laurence,

Now the heartbeat file is created (copied to the shared directory) ~2 minutes after boottime and seems to be attached at least every minute,
but after 11 minutes runtime the VM is killed.

VM Heartbeat file specified, but missing file system status. (errno = '2')

How is the heartbeat file specified in the vbox_job.xml file?

Already testing v26184. VM is running now 23 minutes and still alive. Too early for Hurray!

Typo: heatbeat in stead of heartbeat

Fingers crossed. I didn't get to make my presentation on wish-lists and improvements today. Hopefully Laurence et al. will have squashed a few bugs and introduced new features before its reschedule next week. :-)

Did suspending the task with and without "leave applications in memory" for about 5 minutes.

After the first CMS-job finished, I ended the task gracefully, detached the project (no longer test-running anonymously), attached again and started a new task with the newest stock application.

The Mac version is now available

Not sure whether this is heartbeat not ticking right.
It seems the task was ended in advance of an inside VM-failure and seems to have pushed the shutdown file, but the BOINC-task was reported as computation error.

There was an temporary issue with the credential service. It should be fine again now.

No reason to shutdown the VM, I think and more over boinc_finish gives exit core 1 in stead of exit code 0.

It tried for 2 mins before shutting down. I have increased this to 10 minutes and changed the exit code to 0.
