Configuring the SCI Network Interface
This chapter explains how to configure the SCI network interface in a Sun HPC 3.0
cluster. It covers the following procedures:
4
Creating a temporary network map for later reference – See “Create a Temporary
Network Map for Later Reference” on page 19
4
Creating the SCI configuration file,
sci_config.hpc
– See “Create
sci_config.hpc
” on page 20
4
Running
sm_config
to initialize the SCI network interface – See “Propagate the
SCI Configuration” on page 28
4
Verifying the rank of the SCI interfaces – “Verify the Rank of the SCI Interface”
on page 29
4
Rebooting the cluster nodes – “Reboot Nodes” on page 29
The first section, “Preconditions” on page 17, describes a few conditions that must be
in effect before the SCI interface can be configured.
Preconditions
