InfiniBand networks require a subnet management service that can typically be
run on either an administrative node, or on the switch itself. The optimal placement and
configuration of the
subnet manager is beyond the scope of this document, but \baseOS{} provides the
\texttt{opensm} package should you choose to run it on the {\em master} node.
