# This is an example script for loading IHK, configuring a partition and
|
|
# booting McKernel on it. Unless specific CPUs and memory are requested,
|
|
# the script reserves half of the CPU cores and 512MB of RAM from
|
|
# NUMA node 0 when IHK is loaded for the first time.
|
|
# Otherwise, it destroys the current McKernel instance and reboots it using
|
|
# the same set of resources as it used previously.
|
|
# Note that the script does not output anything unless an error occurs.
