// nodes.basl: A simple scheduler that runs jobs in a 1 job per cpu fashion,
//	       with varying # of cpus residing in one or more nodes.
//	       A sample setup has the following components:
//		 a) nodes list (all must be of cluster type)
//			Under <pbs_home>/server_priv/nodes file contains,
//			host1 np=1
//		        host2 np=2
//			host3 np=3
//		    
//		    NOTE: At most 1 job will run on host1, 2 jobs in host2, and
//			  3 jobs in host3. So via qmgr, adjust np attribute
//			  according to # of jobs to run per node.
//			  Or if you want jobs to share a cpu, then specify
//			  the nodes and neednodes attributes of the job to
//			  "1#shared".
//
//		 b) queues list (set via qmgr)
//
//		    	Queue: long
//   		    	queue_type = Execution
//    		    	Priority = 1
//    		    	resources_min.walltime = 02:00:01
//    			resources_default.nice = -19
//    			resources_default.nodect = 1
//    			resources_default.nodes = 1
//			resources_default.neednodes = 1
//    			resources_default.walltime = 02:00:00
//    			enabled = True
//    			started = True
//
//			Queue: short
//    			Priority = 3
//    			resources_max.walltime = 00:19:59
//    			resources_default.nice = -10
//    			resources_default.nodect = 1
//    			resources_default.nodes = 1
//			resources_default.neednodes = 1
//			resources_default.walltime = 00:05:00
//    			enabled = True
//    			started = True
//
//		c) server list (set via qmgr)
//			Server <hostname>
//			server_state = Active
//			scheduling = True
//			scheduler_iteration = 600
//			default_queue = short
