Boot McKernel
|
||
----------------
|
||
|
||
A boot script called ``mcreboot.sh`` is provided under ``sbin`` in the install
|
||
folder. To boot on logical CPU 1 with 512MB of memory, use the following
|
||
invocation:
|
||
|
||
::
|
||
|
||
export TOP=${HOME}/ihk+mckernel/
|
||
cd ${TOP}
|
||
sudo ./sbin/mcreboot.sh -c 1 -m 512m
|
||
|
||
You should see something similar like this if you display the McKernel’s
|
||
kernel message log:
|
||
|
||
.. code-block:: none
|
||
|
||
./sbin/ihkosctl 0 kmsg
|
||

||
Run a simple program on McKernel
|
||
-----------------------------------
|
||
|
||
The mcexec command line tool (which is also the Linux proxy process) can
|
||
be used for executing applications on McKernel:
|
||
|
||
::
|
||
|
||
./bin/mcexec hostname
|
||
centos-vm
|
||
|
||
Shutdown McKernel
|
||
--------------------
|
||
|
||
Finally, to shutdown McKernel and release CPU/memory resources back to
|
||
Linux use the following command:
|
||
|
||
::
|
||
|
||
sudo ./sbin/mcstop+release.sh
