using PIDs on a cluster is not feasible given there will be different PIDs on different hosts, clkill
can kill processes by name.
Some examples of clps usage:
z
Kill all processes belonging to user 'joeuser'
%
clkill -u joeuser
z
Interactively kill all processes named 'view_server'
% clkill -i -r view_server
will result in a session like:
node0 2260 user1 ? 0:00 view_server
Kill (y/n)? n
node1 8070 user1 ? 0:04 view_server
Kill (y/n)? y
z
Kill a process with PID 2260 on node1
% clkill -C node1 -p 2260

1.6.16 Create a Cluster Group
Groups of Compute Nodes can be created, and added to all tools in ClusterPack
using /opt/clusterpack/bin/clgroup.
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
