Accessing remote hosts

By default, LSF provides commands for running tasks on remote hosts using LSF daemons (lim and res) and LSF ports (LSF_LIM_PORT and LSF_RES_PORT) for communication. Therefore, even if your cluster restricts users from directly logging into or running commands on remote hosts (therefore restricting your users to using LSF batch commands to access remote hosts), users can still run the following commands to run tasks on remote systems under certain circumstances.

lsrun: runs an interactive task on a remote host through LSF. You can run a single task on a single remote host.
lsgrun: runs a task on a set of remote hosts through LSF. You can run a single task on multiple remote hosts.
ch: changes the host on which subsequent commands are to be executed. You can change tasks to run on a selected remote host.
