specifies the host within the cluster on which the job(s) are to be run. The host argument is the name of a host that is a member of the cluster of hosts managed by the server. If the option is not specified, the server will select the "worst possible" host on which to execute the job.
The qrun command is used to force a batch server to initiate the execution of a batch job. The job is run regardless of scheduling position or resource requirements.
In order to execute qrun, the user must have PBS Operation or Manager privilege.
