Performance enhancements and bug fixes
Other Changes
The following changes have been made to the software since the last release:
ipath_ether Ethernet emulation has been removed; IPoIB-CM can be
used instead.
The /etc/init.d/infinipath command to start the InfiniPath service
has been replaced by the /etc/init.d/openibd command.
The infinipath-kernel RPM no longer exists; it has been integrated
into the kernel-ib RPM.
Continued Support
The following features are still supported in this release:
Multiple high-performance native PSM MPI implementations. (PSM is
QLogic’s accelerated library for high performance MPIs). In addition to
QLogic MPI, the currently supported MPI implementations are HP-MPI,
Open MPI, MVAPICH, and Scali (Platform). Open MPI provides MPI-2
functionality, including one-sided operations and dynamic processes. These
all offer the same high performance as QLogic MPI.

Dual PCIe QLogic adapters per node.
4K Maximum Transfer Unit (MTU) is supported and is on by default. To take
advantage of 4KB MTU, use a switch that supports 4KB MTU. QLogic also
supports 2KB switches, as well as 4KB MTU switches configured for 2KB
MTU. QLogic switches with firmware version 4.2.x or later are
recommended.
