InfiniPath and OpenFabrics Driver Overview
The InfiniPath ib_ipath module provides low level QLogic hardware support, and is the base driver for both the InfiniPath and OpenFabrics software components. The ib_ipath module does hardware initialization, handles
It provides the hardware and hardware management functions for MPI/PSM programs, the ipath_ether Ethernet emulation, and general OpenFabrics protocols such as IPoIB and SDP. The module also contains a subnet management agent.
Figure 5-1 shows the relationship between the InfiniPath and OpenFabrics software. Not all components are shown.

If you want to enable Transmission Control
NOTE:
It is not necessary to configure the ipath_ether driver to run MPI jobs.
Optional configurable OpenFabrics components are:
IPoIB network interface
VNIC
OpenSM
SRP (OFED and QLogic modules)
MPI over uDAPL (can be used by Intel MPI or
