Next, edit sci_config.hpc. Every template type is organized into eight sections.
Instructions for editing each section are provided below.
Section 1 – Cluster Configuration Type
Section 1 asks you to specify the type of cluster you have; you are given the options:
SC (Sun Cluster) or HPC. Enter HPC, as follows:
Cluster is configured as = HPC
SC is not a valid entry for clusters running Sun HPC ClusterTools software.
Section 2 – Host Names
List all of the nodes in the cluster by replacing <host_namen> placeholders with the
host names of the cluster's nodes. For example, if your cluster contains the nodes:
node3, node4, node5, and node6, Section 2 should look like this:
HOST 0 = node3
HOST 1 = node4
HOST 2 = node5
HOST 3 = node6
The nodes can be listed in any order.
Section 3 – Number of Switches
Specify the number of SCI switches in the cluster. This will be determined by which
network topology you implement, as follows:
4 Two-node cluster – either nonstriped or striped, set
Number of Switches in cluster = 0
4 Three- or four-node cluster – nonstriped, set
