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 

Information on clusters, supported distributions and kernels, and environment 
setup is provided in

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.
