Node states have the following definitions:

State	Description
Busy	Node is running some jobs and will not accept additional jobs
Down	Resource Manager problems have been detected. Node is incapable of running jobs.
Draining	Node is responding but will not accept new jobs
Idle	Node is ready to run jobs but currently is not running any.
Running	Node is running some jobs and will accept additional jobs
Unknown	Node is capable of running jobs but the scheduler will need to determine if the node state is actually Idle, Running, or Busy.

W.1.2 Query Workload Data Format

DPROCS	<INTEGER>	1	number of processors dedicated per task
DSWAP	<INTEGER>	0	quantity of virtual memory (swap, in MB) which must be dedicated to each task of the job
ENDDATE	<EPOCHTIME>	[ANY]	time by which job must complete

GNAME*	<STRING>	---	GroupID under which job will run
HOSTLIST	comma or colon delimited list of hostnames - suffix the hostlist with a carat (^) to mean superset; suffix with an asterisk (*) to mean subset; otherwise, the hostlist is interpreted as an exact set	[ANY]	list of required hosts on which job must run. (see TASKLIST) A subset means the specified hostlist is used first to select hosts for the job. If the job requires more hosts than are in the hostlist, they will be obtained from elsewhere if possible. If the job does not require all of the jobs in the hostlist, it will use only the ones it needs. A superset means the hostlist is the only source of hosts that should be considered for running the job. If the job can't find the necessary resources in the hosts in this list it should not run. No other hosts should be considered in allocating the job.

NODES	<INTEGER>	1	Number of nodes required by job (See Node Definition for more info)

SUSPENDTIME	<INTEGER>	0	Number of seconds job has been suspended
TASKLIST	one or more comma-delimited <STRING>'s	---	list of allocated tasks, or in other words, comma-delimited list of node ID's associated with each active task of job (i.e., cl01, cl02, cl01, cl02, cl03) The tasklist is initially selected by the scheduler at the time the StartJob command is issued. The resource manager is then responsible for starting the job on these nodes and maintaining this task distribution information throughout the life of the job. (see HOSTLIST)
TASKS*	<INTEGER>	1	Number of tasks required by job (See Task Definition for more info)
TASKPERNODE	<INTEGER>	0	exact number of tasks required per node
UNAME*	<STRING>	---	UserID under which job will run

Job states have the following definitions:

State	Definition
Completed	Job has completed
Hold	Job is in the queue but is not allowed to run
Idle	Job is ready to run
Removed	Job has been canceled or otherwise terminated externally
Running	Job is currently executing
Suspended	job has started but execution has temporarily been suspended

Completed and canceled jobs should be maintained by the resource manager for a brief time, perhaps 1 to 5 minutes, before being purged. This provides the scheduler time to obtain all final job state information for scheduler statistics.
