Openmosix is not designed for parallel jobs, for that, use MPI.
However, if you have different simulations to run (many jobs), mosix if 
perfect for you!

To get jobs migrating automatically, use this command:

mosrun -l mdrun ...

Or, if you want to skip the pre-command mosrun, 
Insert this line below at /etc/profile 

echo 0 > /proc/self/lock

Nevertheless, with this setup, *any* job may migrate and maybe your 
cluster can be unstable.  Do a series of tests before real long time 
simulations, or live with 'mosrun'.
