5Software Installation
This section provides instructions for installing QLogic OFED 1.4, which includes
QLogic InfiniPath and the OpenFabrics software. The software includes drivers,
protocol libraries, QLogic’s implementation of the MPI message passing standard,
associated utilities, and example programs, including benchmarks. A complete list
of the provided software is in “Software Components” on page2-4.
Cluster Setup
Information on clusters, supported distributions and kernels, and environment
setup is provided in “Types of Nodes in a Cluster Environment” on page5-1,
“Supported Linux Distributions” on page 5-1, and “Distribution Identifiers” on
page 5-2.
Types of Nodes in a Cluster Environment
In a cluster environment, different nodes can be used for different functions, such
as launching jobs, developing software, or running jobs. The nodes are defined as
follows:
Front end node. This node launches jobs.
Compute node. This node runs jobs.
Development or build node. These are the machines on which examples
or benchmarks can be compiled.
Any machine can serve any combination of these three purposes, but a typical
cluster has many compute nodes and just a few (or only one) front end nodes.
The number of nodes used for development will vary. These node names are
used throughout this guide.
Supported Linux Distributions
The QLogic interconnect runs on AMD™ Opteron™ and 64-bit Intel Xeon systems
running Linux®. The currently supported distributions and associated Linux kernel
versions for InfiniPath and OpenFabrics are listed in Table5-1.
The kernels are the ones that shipped with the distributions. All are for the x86_64
architecture.
