ClusterPack Tutorial

List all processes on node3 and node4

% clps -C node3+node4 -a

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

man clps

1.6.15 Kill a user's process (or all of the user's processes) on some/all Cluster

Nodes

The 'clkill' command in /opt/clusterpack/bin is used to kill processes on Cluster Nodes. Since

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:

Kill all processes belonging to user 'joeuser'

clkill -u joeuser

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

Kill a process with PID 2260 on node1

% clkill -C node1 -p 2260

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

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.
