This API provides information about the jobs and machines in the LoadLeveler cluster. You can use this in conjuction with the job control API, since the job control API requires you to know which machines are available and which jobs need to be scheduled. See Workload Management API for more information.
The query API consists of the following subroutines: ll_get_jobs, ll_free_jobs, ll_get_nodes, and ll_free_nodes.
