2 Feature Overview
This section contains the features for this release, the supported QLogic adapter
models, supported distributions and kernels, and a list of the software
components.
Features
The QLogic OFED 1.4 software release contains the complete OFED 1.4, plus
additional QLogic improvements, including an enhanced QLogic Host Channel
Adapter driver. The InfiniPath 2.3 components (libraries, QLogic
Message-Passing Interface/Performance Scaled Messaging (MPI/PSM), and
utilities) are also included. QLogic also supplies MVAPICH and OpenMPI
compiled with new versions of four different compilers (see the following list).
The following features and enhancements are included in the QLogic OFED 1.4
release:
Installation improvements. A single software load is provided for InfiniBand
host channel adapters from QLogic and other vendors supported by OFED.
The software is available in the following package formats:
Text User Interface (TUI) installer (with the QLogicIB-Basic download).
TUI is used for installation on smaller clusters. Software can be
installed either by itself or through FastFabric™ (if the QLogic
InfiniBand Fabric Suite (IFS) is purchased).
Software packaged for use with the rpm install method.
A subset of the software (the accelerated MPI stack, precompiled
versions of MVAPICH and Open MPI, and other user-level tools) can
be installed on top of stock OFED or on an IB-enabled distribution.
Software packaged for the Rocks installation method.
Software packaged for the Platform Open Cluster Stack (OCS)
installation method.
Write Combining (WC) mappings for the PIO buffers is now configured by
default using the x86 Page Attribute Table (PAT) mechanism.
MVAPICH and OpenMPI are compiled with new versions of the following
compilers: GCC, PGI, Intel
®
, and PathScale™.
