How do I configure the mdce service to start automatically at boot on Linux/Unix cluster nodes?

I have an MATLAB Parallel Server cluster comprised of Linux/Unix worker nodes which uses the MathWorks JobManager (mdce service). I would like to configure the mdce service to start automatically when the nodes boot.

To configure the mdce service to start at system boot, follow the appropriate instructions below depending on your OS distribution type:

=====

Debian Platform

=====

On each cluster node, register the mdce service as a known service and

configure it to start automatically at system boot time by following these steps:

1. Create the following link, if it does not already exist:

ln -s matlabroot/toolbox/distcomp/bin/mdce /etc/mdce

2. Create the following link to the boot script file:

ln -s matlabroot/toolbox/distcomp/bin/mdce /etc/init.d/mdce

3. Set the boot script file permissions:

chmod 555 /etc/init.d/mdce

4. Look in /etc/inittab for the default run level. Create a link in the rc

directory associated with that run level. For example, if the run level is 5,

execute these commands:

cd /etc/rc5.d;
ln -s ../init.d/mdce S99MDCE

=====

SUSE Platform

4. Look in /etc/inittab for the default run level. Create a link in the rc

directory associated with that run level. For example, if the run level is 3,

execute these commands:

cd /etc/rc3.d;
ln -s ../init.d/mdce S99MDCE
