[Beowulf] mpirun and batch systems

Hello -

I have a question about how various batch systems run MPI jobs.

Say I have a head node and 16 compute nodes. I submit a job
that requires 8 nodes, and the batch system allocates me
nodes 4,5,6,7,8,9,10,11. 

Where does my 'mpirun' get executed from? On the head node? Or on
node 4?
