The following sections contain detailed descriptions of the RPMs for InfiniPath and 
OpenFabrics software. 

For ease of installation, QLogic recommends that all RPMs are installed on all 
nodes. However, some RPMs are optional. Since cluster nodes can be used for 
different functions, it is possible to selectively install RPMs. For example, you can 
install the opensm package for use on the node that will act as a subnet manager. 

If you want to selectively install the RPMs, see the following tables for a 
comparison of required and optional packages.

In a cluster environment, different nodes may be used for different functions, such 
as launching jobs, software development, or running jobs. These nodes are 
defined as follows:

„

Front end node. This node launches jobs. It is referred to as the front end 
node throughout this document.

„

Compute node. These nodes run 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. Although QLogic 
recommends installing all RPMs on all nodes, not all InfiniPath software is 
required on all nodes. See 

information on installation of software RPMs on specific types of nodes. 

The InfiniPath RPMs that are shipped have the InfiniPath release number and the 
build versions contained in the RPM name. The architecture is designated by 
x86_64, noarch, or i386, and is dependent upon the distribution. For example:

infinipath-2.2-33597.832_rhel4_qlc.x86_64.rpm

In this RPM, 2.2 is the InfiniPath release, and 33597.832 are the build versions.
