OFED+ Host SW
• Shared Memory (SHMEM) is included in the ./INSTALL TUI menus as a selection.
SHMEM will be installed by default and will also be installed if
mpi or psm_mpi or
mpidev is selected on the command line. To function, SHMEM requires that at least
one MPI be installed on the system. This requirement of one MPI being installed is
not enforced by ./INSTALL TUI.
SHMEM is a user-level communications library for one-sided operations. It
implements the SHMEM Application Programming Interface (API) and runs on the
Intel
®
InfiniBand* (IB) stack. The SHMEM API provides global distributed shared
memory across a network of hosts.
SHMEM is quite distinct from local shared memory (often abbreviated as “shm” or
even “shmem”). Local shared memory is the sharing of memory by processes on
the same host running the same OS system image. SHMEM provides access to
global shared memory distributed across a cluster. The SHMEM API is completely
different from and unrelated to the standard System V Shared Memory API
provided by UNIX operating systems.
• The questions for autostart enable of components have been replaced with an
interactive menu showing all the autostart selections in both the ./INSTALL TUI and
the
iba_config script.
• The version required for the PGI compiler has been upgraded from “9.0.4 or later”
to “10.5 or later.” The upgrade to 10.5 is required for proper operation of
MVAPICH2 version 1.7.
• NVIDIA CUDA 4.0 and 4.1 have been tested and are supported.
1.4.6 Release 7.0.1 Features
• The iba_manage_switch script, along with the xedge tools, is included as part of
IB-Basic (OFED+) allowing customers not using the IFS software to manage
externally managed switches. Unlike FastFabric, it is designed to operate on one
switch at a time, taking a mandatory target GUID parameter.

information.
• Performance tuning parameters for the QLE7340 and QLE7342 drivers can now be
set on a per port or per unit basis. If there are two HCAs (HCA) in a server, settings
for one HCA can be optimized for storage traffic and settings for the other HCA can
be optimized for MPI traffic. Please see the Intel
®
True Scale Fabric OFED+ Host
Software User Guide for details.
