When running the OFED performance benchmark qperf to test the bandwidth of Unreliable Datagram (UD) traffic, the command no longer hangs or times out intermittently when using an InfiniBand MTU of 4096 bytes and the '-t 10' (or larger number of seconds).
Known Issue Test rdma_bw fails if it detects conflicting CPU frequencies. Workaround Ensure that the same cpu frequancies are at both ends when using rdma_bw. When using vFabric to change an IPoIB application After changing the application, restart the network from Networking to Non-Networking, the IPoIB services or bring the interface down/up to force interface may remain in a running state. IPoIB to re-query the SM and correct the situation.
Known Issue Workaround When installing the QLogicIB on a freshly kickWhen using QLogic MPI on RHEL 6 or later RedHat started RHEL 6 node, QLogic MPI programs will not distributions the following compatibility gfortran library RPMs must be installed: run. compat-libgfortran-41-4.1.2-39.el6.i686.rpm compat-libgfortran-41-4.1.239.el6.x86_64.rpm These RPMs are provided by the RHEL distribution. If these RPMs are not installed QLogic MPI programs will fail to run due to not finding the libgfortran.so.

5.5 Special PCM Installation for RHEL 5.6 and SLES 11 SP1 Platform PCM 3.0 Standard Edition for RHEL 5.6 and SLES 11 SP1 requires an updated RPM to enable the QLogic GUI (portal) menu items for launching FastFabric and Fabric Viewer. The RPM can be obtained from Platform Computing’s web site. Once installed, these menu items are available in the Common Tasks drop down menu on the Platform portal main screen (dashboard view). To install the PCM using the builds, use the following instructions: 1.
5.6 New Features The following are the new features for the QLogic OFED+ Host software package. 5.6.1 Release 7.0 Features New automatic performance tuning utility: ipath_perf_tuning can be run as root to set the qib driver parameters in the modprobe.conf file.
5.7 Product Constraints The version of OpenMPI shipped with QLogicIFS is incompatible with the Performance Application Programming Interface ("papi") libraries available in RedHat Enterprise version 6. If you try to recompile the provided version of OpenMPI on RedHat 6 you will first have to uninstall any installed version of papi-4.x. Older versions of papi (papi-3.x) are still compatible with the shipped version of OpenMPI.
5.9 Other Information When using Mellanox Host Channel Adapters, any changes to Virtual Fabrics (vFabrics) in the Fabric Manager, may require a reboot of the hosts with Mellanox Host Channel Adapters. This limitation relates to the Mellanox Host Channel Adapters not properly responding to changes to the Fabric Manager service level (SL).
When upgrading from an older QLogic OFED+ release to a new QLogic OFED+, the older QLogic OFED+ release will be uninstalled first. When installing the OFED Debug Info component, make sure that ~/.rpmmacros does not have any lines changing the %debug_package macro. If %debug_package is set to %{nil}, debuginfo RPMs will not be available for installation.
An SRP write performance bug between QLE7240/QLE7280 and LSI (Engenio) storage systems was fixed. To apply this fix, modify the srp_sg_tablesize and max_sect parameters. To modify srp_sg_tablesize, do one of the following: Add the following line to /etc/modprobe.conf: options ib_srp srp_sg_tablesize=80 Define srp_sg_tablesize when adding the ib_srp module (as root): modprobe ib_srp srp_sg_tablesize=80 If using srp_daemon, modify max_sect by adding the following command to /etc/srp_daemon.
