    Description

      How to trigger the kernel panic:

      1. start-up amplxe-gui and create a new project, e.g. "test".

      2. Then set the executable to use to say /bin/ls.

      3. Now create a new analysis and select any of the ones available to your process architecture and run it.

      4 .Once the simulation has completed, exit amplxe-gui.

      5. Load amplxe-gui again and re-run the simulation in step 3.

      6. Exit amplxe-gui once the simulation completes.

      7. Repeat steps 5 to 6 until the node kernel panics (normally takes three or four attempts)

      It should be noted that users' home directories are stored on Lustre and also the environment variable $TMPDIR is set to a directory within users' homespaces on Lustre. The Vtune "project files" are therefore stored on Lustre. I suspect that the reading or writing of these files by Vtune could be the cause of the kernel panic.
