3.1.8 clps - Cluster-wide ps command

clps and clkill are the same program with clps producing a "ps" output that includes the host

name and clkill allowing processes to be killed.

clps is used as follows:

clps [-C] cluster][-ad]{tty user command pid regexp}

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

% man clps

3.1.9 clkill - Kills specified processes on specified nodes.

clps and clkill are the same program with clps producing a "ps" output that includes the host

name and clkill allowing processes to be killed. Since using PIDs on a cluster is not feasible

given there will be different hosts, clkill can kill processes by name. The -i option should be

assed to clkill to allow interactive killing; i.e. any matches are shown and the user is

rompted if they wish to kill that process.

clkill is used as follows:

% clkill [[-C] cluster][-signal][-ilnadv]{tty user command pid

regexp}

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

man clkill

3.1.10 clinfo - Shows nodes and cluster information.

The clinfo command lists which hosts make up a cluster. By default, with no arguments, the

current cluster is listed. Non-flag arguments are interpreted as cluster names. Three different

output modes are supported.
