This API provides information about the jobs and machines in the LoadLeveler cluster. You can use this in conjunction with the workload management API, since the workload management API requires you to know which machines are available and which jobs need to be scheduled. See Workload Management API for more information. These APIs exist for backward compatibility. It is recommended that you use the Data Access API when possible.
The query API consists of the following subroutines: ll_get_jobs, ll_free_jobs, ll_get_nodes, and ll_free_nodes.
