1 Introduction
How this Guide is Organized
The QLogic OFED+ Host Software User Guide is organized into these sections:
 Section 1, provides an overview and describes interoperability.
 Section 2, describes how to setup your cluster to run high-performance MPI
jobs.
 Section 3, describes the lower levels of the supplied QLogic OFED+ Host
software. This section is of interest to a InfiniBand
®
cluster administrator.
 Section 4, helps the
Message Passing Interface (MPI) programmer make the
best use of the Open MPI implementation. Examples are provided for
compiling and running MPI programs.
 Section 5, gives examples for compiling and running MPI programs with
other MPI implementations.
 Section 7, describes QLogic Performance Scaled Messaging (PSM) that
provides support for full Virtual Fabric (vFabric) integration, allowing users to
specify InfiniBand
®
Service Level (SL) and Partition Key (PKey), or to
provide a configured Service ID (SID) to target a vFabric.
 Section 8, describes dispersive routing in the InfiniBand
®
fabric to avoid
congestion hotspots by “sraying” messages across the multiple potential
paths.
 Section 9, describes open-source Preboot Execution Environment
(gPXE)
boot including installation and setup.
 Appendix A, describes how to run QLogic’s performance measurement
programs.
 Appendix B, describes SCSI RDMA Protocol (SRP) configuration that allows
the SCSI protocol to run over InfiniBand
®
for Storage Area Network (SAN)
usage.
