# This is an example script for loading IHK, configuring a partition and
# booting McKernel on it.
# The script reserves half of the CPU cores and 512MB from NUMA node 0 if
# IHK is loaded for the first time, otherwise it destroys the current
# McKernel instances and reboots it using the same set of resources as previously.

# Note that the script does not output anything unless an error occurs.
