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.
