ClusterPack Tutorial

The following example creates a node group "cae" containing compute cluster nodes "lucky000",

"lucky001", and "lucky002":

/opt/clusterpack/bin/clgroup -a cae lucky000 lucky001 lucky002

clgroup can also form groups from existing groups. For more details on the usage of clgroup,

invoke the command:

man clgroup

1.6.17 Remove a Cluster Group

Groups of Compute Nodes can be removed from ClusterPack using /opt/clusterpack/bin/clgroup.

The following example removes the node group "cae":

% /opt/clusterpack/bin/clgroup -r cae

ote that the above-mentioned command just removes the group; the nodes are still part of the

cluster, and users can submit jobs to the nodes.

For more details on the usage of clgroup, invoke the command:

% man clgroup

1.6.18 Add Nodes to a Cluster Group

Compute Nodes can be added to existing groups in ClusterPack

using /opt/clusterpack/bin/clgroup.

The following example adds nodes "lucky006" and "lucky008" to the node group "cae" :

/opt/clusterpack/bin/clgroup -a cae lucky006 lucky008

Groups can also be created or extended using the name of a pre-existing group. For more details

on the usage of clgroup, invoke the command:

man clgroup
