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.
All installation and uninstallation of QLogic OFED+ Host software package components
must be performed using the ./INSTALL or iba_config commands. If software is
manually installed or uninstalled using other methods (RPM, other scripts, and so on),
the installation on the system could become inconsistent and cause unreliable operation,
in which case subsequent runs of ./INSTALL or iba_config may make incorrect
conclusions about the configuration of the system and consequently make incorrect
recommendations. If the system becomes inconsistently configured, QLogic recommends
running the ./INSTALL TUI and selecting ReInstall on all components. Once the re-
installation has started, carefully review all prompts and choices.
On SuSE systems, NETWORKMANAGER must be set to "no" in
/etc/sysconfig/network/config. This is the default setting.
The mpirun command in this release is not compatible with nodes running InfiniPath
releases prior to version 2.2.1.
OFED SDP has not been qualified for this release. IPoIB is recommended for data
transfers.
5.8 Product Limitations
QLogic products will auto-negotiate with devices that utilize IBTA-compliant auto-
negotiation. When attaching QLogic products to a third-party device, the bit error rate is
optimized if the third-party device utilizes attenuation-based tuning.
At the time of this release, Oracle has not certified InfiniBand adapters for RDS. As a
result, QLogic is unable to extend support for RDS.
At the time of this release, the PathScale Compiler Suite is not supported for SLES11.
As a result, QLogic is unable to extend support for this environment.
