Version 1.1

• Utility programs: prm_jobs for checking status of running jobs, prm_stat to query the status of a system manager and the nodes it manages, and prm_shutdown to gracefully shut down a PRM system.

• Use of ACLs: System manager uses an access control list to determine whether the host requesting resources is authorized to use nodes.

• Library routines : io_puts, io_gets, io_tputs, io_tgets for standard I/O to tasks, prm_create_task, prm_aq_rsc and prm_terminate_job for task creation and resource management.

• Local node manager not required: it is no longer necessary to run a node manager on the host on which a job is initiated.

• Unless configured with the -r option, the node manager will only execute programs residing in $PRM_TOP/bin/$ARCH.
