Editorial Comment: To be checked with openMosix versions
Login a normal terminal as root. Type
which, if everything went right, will give you a listing of your
/etc/mosix.map. If things did not go right, try
setpe -w -f /etc/mosix.map
to set up your node.
to see if your child processes are locked in your mode (1) or can
migrate (0). If for some reason you find your processes are locked,
you can change this with

Repeat the whole configuration scheme for a second computer.
The programs tune_kernel and prep_tune that Mosix uses to calibrate
the individual nodes do not work with the SuSE distribution.
However, you can fake it. First, bring the computer you want to
tune and another computer with Mosix installed down to single user
mode by typing
as root. All other computers on the network should be shutdown if
On both machines, run the following commands:
echo 1 > /proc/mosix/admin/quiet
This fakes prep_tune and the first parts of tune_kernel. Note that
if you have a laptop with a pcmcia network card, you will have to
instead of "/etc/init.d/network start".
On the computer you want to tune, run tune_kernel and follow
instructions. Depending on your machines, this can take a while -
if you have a dog, this might be the time to go on that long, long
walk you've always promised him.
tune_kernel will create a program called "pg" in /root for testing
reasons. Ignore it.
After tuning is over, copy the contents of /tmp/overheads to the
file /etc/overheads (and/or recompile the kernel).
Repeat the tuning procedure for each computer. Reboot, enjoy Mosix,
don't forget to brag to your friends about your new cluster.
