2) As far as I understand, I need the opensm subnet manager. Can I run this
manager on the head node (which has
no IB NIC)
    

An IB NIC (HCA) is needed to run OpenSM or any host based SM.

  
Some IB switches also have an SM built in, but you may not have  a choice of switches. Basically, like Hal said, the SM must be connected to the IB fabric.
