on SUSE 9.3,
SLES 9, and SLES 10.
3.2.3
Kernel Patches
Some kernels, such as some versions of Fedora Core 4 (2.6.16), have
CONFIG_PCI_MSI=n
as the default. If the InfiniPath driver is being compiled on a
machine without
CONFIG_PCI_MSI=y
configured, you will get a compilation error.
This default may also be introduced with updates to other Linux distributions or local
configuration changes.
NOTE: IBM provides a pre-installed patched kernel For Power systems.
Systems that use the InfiniPath QLE7140, contain an AMD-8131 south bridge and
use kernels between 2.6.12 - 2.6.16 require a patch for a problem that disabled the
use of MSI interrupt handlers, which are used with the QLE7140.
NOTE: This does not apply to Power systems running SLES 10.
InfiniPath-specific kernels and patches for these problems are available for
download on the QLogic web site. Please go to:
http://www.qlogic.com
Follow the links to the download pages. This topic is also covered in appendix C.4
in the InfiniPath Interconnect User Guide .
3.2.4
Types of Nodes in a Cluster Environment
In a cluster environment different nodes may be used for different functions, such
as launching jobs, for software development, or running jobs. We define these nodes
in the following way:
■
Front end node . This node will launch jobs. It is referred to as the front end node
in this documentation.
■
Compute node . These are the nodes that are used to run jobs.
■
A 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 only one or just a few front end nodes. The
number of nodes used for development will vary. The terms defined above will be
used in the rest of the documentation.
