6 Configuring Drivers and Services

This section provides instructions for configuring and using the drivers and services available with QLogic OFED 1.4.

InfiniPath and OpenFabrics Driver Overview

The InfiniPath ib ipath module provides low level QLogic hardware support, and is the base driver for both MPI/PSM programs, and general OpenFabrics protocols such as IPoIB and SDP. The driver also supplies the Subnet Management Agent (SMA) component.

Optional configurable OpenFabrics components and their default settings at startup are:

„IPoIB network interface. Required for TCP/IP networking for running Ethernet traffic over the InfiniPath link. It is not running until it is configured.

„VNIC. It is not running until it is configured.

„OpenSM. It is disabled on startup. You can either install it on only one node, or disable it on all nodes except where it will be used as an SM.

„SRP (OFED and QLogic modules). SRP is not running until the module is loaded and the SRP devices on the fabric have been discovered.

„MPI over uDAPL (can be used by Intel MPI or HP-MPI). IPoIB needs to be configured before MPI over uDAPL can be set up.

Other optional drivers can now be configured and enabled, as described in “OpenFabrics Drivers and Services Configuration and Startup” on page 6-1.

Complete information about starting, stopping, and restarting the InfiniPath services are in “Managing the InfiniPath Driver” on page 6-15.
