Click here to display the system's profile data or here to proceed to next system.
Click on a legend element to toggle display of that core, ctrl-click inverts display, shift-click enables all.

Note that this system runs a non-RT kernel.
Data to construct the above plot have been generated using the RT test utility cyclictest.
