5 Software Installation
This section provides instructions for installing the InfiniPath and OpenFabrics
software. The InfiniPath software includes drivers, protocol libraries, QLogic’s
implementation of the MPI message passing standard, and example programs,
including benchmarks. A complete list of the provided software is in “Software
Components” on page 2-4.
Cluster Setup
Information on clusters, supported distributions and kernels, and environment
setup is provided in “Types of Nodes in a Cluster Environment” on page 5-1,
“Supported Linux Distributions” on page 5-2, and “Setting Up Your Environment”
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.
