InfiniBand® Cluster Setup
and Administration
This section describes what the cluster administrator needs to know about the
QLogic OFED+ software and system administration.
Introduction
The IB driver ib_qib, QLogic Performance Scaled Messaging (PSM), accelerated
Message-Passing Interface (MPI) stack, the protocol and MPI support libraries,
and other modules are components of the QLogic OFED+ software. This software
provides the foundation that supports the MPI implementation.
Figure 3-1 illustrates these relationships. Note that HP-MPI, Platform MPI, Intel
MPI, MVAPICH, MVAPICH2, and Open MPI can run either over PSM or
OpenFabrics® User Verbs.
