RN 7.2.2.0.8 February 2014
6 Order Number: H31512002US
and PSM_MULTIRAIL_MAP enable this feature. More details can be found in the
Intel

True Scale Fabric OFED+ Host Software User Guide.
• This release includes fixes in performance-related issues for IPoIB and verbs which
provide significant improvement in IPoIB bandwidth and latency and improvement
in RDMA/verbs bandwidth.
• Added support for RedHat EL 6.3 and RedHat EL 5.9
• qlgc_srp and qlgc_vnic packages are dropped from version 7.2 onwards. On new
installation or upgrades of version 7.2, these packages will be removed from the
host.
• Branding for Intel has been incorporated in this release. The following packages are
included in the branding effort:
— OFED+ IB-Basic
— OFED_MPIs
— OPENIB_ROLL
1.4.4 Release 7.1.1 Enhancements
• The “Optimal Assignment of PSM Processes to HCAs” enhancement added in this
release automatically improves MPI/PSM performance to the greatest extent in
systems where the following conditions are in effect:
1. The OS and CPUs support NUMA (Non-Uniform Memory Architecture) and
NUMA node to I/O device binding.
2. Two HCAs connect to different PCIe root complexes which, in turn, connect to
different NUMA nodes.
Typical systems where these conditions hold are those with two or more Intel
®
Xeon
®
Processor E5 2600 series CPUs (known as Sandy Bridge) with dual HCAs in
slots connected to the PCIe root complexes in different CPUs, running RHEL 6.1, or
SLES 11 SP1 or newer operating systems.These enhancements will also offer some
additional performance improvement on systems with one HCA.
There are systems based on other CPUs that have not been tested to verify the
performance gain, where conditions 1 and 2 hold. Systems where the OS does not
support conditions 1 and 2 will still get a performance benefit from two HCAs
versus one HCA.
To determine if conditions 1 and 2 hold in a system refer to Appendix A
1.4.5 Release 7.1 Features
• rnfs-utils command was removed by Open Fabrics and is not included in OFED
1.5.4.1.
• iscsi and iSER Target packages were removed by Open Fabrics and are not included
in OFED 1.5.4.1. When installing Intel
®
OFED+, any previous versions of these
packages already on the system will not be affected. Intel
®
recommends to
uninstall these packages using the
iba_config script or ./INSTALL TUI from the
previous version prior to installing the new version. One exception is
scsi-target-utils, which will be removed if found on the system.
• MPI is no longer installed or included in the release. If found on the system when
installing or un-installing the Intel
®
libraries, it will be removed. Several MPIs
including Intel MPI, Open MPI, MVAPICH, and MVAPICH2 continue to be supported
with this release. To aid in the transition please consult the examples in the Intel
®
True Scale Fabric OFED+ Host Software User Guide.
