Configuration Control

A Sun HPC cluster contains one or more named partitions. Each partition contains some number of specific nodes. Likewise, each node includes one or more network interfaces that it uses for internode communication.

The CRE automatically creates the cluster, node, and network interface objects based on the contents of the hpc.conf file. Partitions are the only kind of object that the system administrator is required to create and manage.

Use the delete command to remove partitions, but no other types of cluster objects. Your remove nodes and network interfaces from a Sun HPC cluster by editing the hpc.conf file.

create

Usage:

:: create object-name

Available In:

Node, Partition, Network

The create command creates a new object with the name object-name and makes the new object the current context.

Note, partitions can only be created from within the Partition context. The following example creates the partition part0.

[node0]
Partition:: create part0[node0] P(part0)::

As the second line in the example shows, part0 becomes the new context.

delete

Usage:

:: delete [object-name]

Available In:

Node, Partition, Network

The delete command deletes the object specified by the object-name argument. The object being deleted must either be contained in the current context or must be the current context. The first example shows a partition contained in the current context being deleted.

[node0]
Partition:: delete part0[node0] Partition:: 

If the current context is the object to be deleted, the object-name argument is optional. In this case, the context reverts to the next higher context level.

[node0]
P(part0):: delete[node0] Partition::
