DESCRIPTION


.Iq
.Tc Public Job Attributes
.Ig

A batch job has the following public attributes shown in the following list. The attributes marked with the section symbol § are required by POSIX 1003.2d: If an attribute is unset, the indicated default value is assumed.
Account_Name §
.Ig
Account_Name §
.Ig Used for accounting on some hosts. A server may not use the string, but allowances for it must be made.
.Ig Format: string; default value: none, not used. [internal type: string]
.Ig
Checkpoint §
.Ig
Checkpoint §
.Ig If supported by the server implementation and the host operating system, the checkpoint attribute determines when checkpointing will be performed by PBS on behalf of the job. The legal values for checkpoint are described under the qalter and qsub commands. Format: the strings "n", "s", "c", "c=mmmm"; default value: "u", which is unspecified. [internal type: string]
.Ig
depend
.Ig
depend
.Ig The type of inter-job dependencies specified by the job owner. Format: "type:jobid[,jobid...]"; default value: no dependencies. [internal type: special, dependency]
.Ig
Error_Path §
.Ig
Error_Path §
.Ig The final path name for the file containing the job’s standard error stream. See the qsub and qalter command description for more detail. Format: "[hostname:]pathname"; default value: (job_name).e(job_number). [internal type: list]
.Ig
Execution_Time §
.Ig
Execution_Time §
.Ig The time after which the job may execute. The time is maintained in seconds since Epoch. If this time has not yet been reached, the job will not be scheduled for execution and the job is said to be in wait state. Format: "[[CCwYY]MMDDhhmm[.ss]"; default value: time 0, no delay. [internal type: integer]
.Ig
group_list §
.Ig
group_list §
.Ig A list of which determines the group under which the job is run on a given host. [internal type: array of strings] When a job is to be placed into execution, the server will select a group name according to the following ordered set of rules:
1. Select the group name from the list for which the associated host name matches the name of the execution host.
2. Select the group name which has no associated host name, the wild card name.
3. Use the login group for the user name under which the job will be run.
Format: "group_name[@host][,group_name[@host]...]". [internal type: array of strings]
.Ig
Hold_Types §
.Ig
Hold_Types §

Note, the hold state takes precedence over the wait state. Format: string made up of the letters ’u’, ’s’, ’o’; default value: no hold. [internal type: string]
.Ig
Job_Name §
.Ig
Job_Name §
.Ig The name assigned to the job by the qsub or qalter command. Format: string up to 15 characters, first character must be alphabetic; default value: the base name of the job script or STDIN. [internal type: string]
.Ig
Join_Path §

overrides the and attributes. Format: "o", "e", "oe" or "eo"; default value: no keep, return files to submission host. [internal type: string]
.Ig
Mail_Points §
.Ig
Mail_Points §

.Tc Privileged Job Attributes
.Ig
The following attributes require system, manager, or operator privilege to set. They are visible to clients depending on privilege as noted.
comment
.Ig
comment
.Ig An attribute for displaying comments about the job from the system. Visible to any client. Format: any string; default value: none. [internal type: string]
.Ig
sched_hint
.Ig
sched_hint
.Ig This attribute is present when the job is a member of a synchronous dependency set. It is set when the hold is released on the job. The value is {SYNC_SCHED_HINT_FIRST} (1) when the first job of the set is released for scheduling. This is a hint that may be used by the scheduler to decrease the priority of the job. This keeps a user from attempting to game the scheduler. The attribute is set to {SYNC_SCHED_HINT_OTHER} (2) for all other jobs in the set as they become schedulable. This should be taken as a hint by the scheduler to increase their priority to insure they will run at the same time as the earlier scheduled jobs in the set. [This attribute is viewable only by the batch administrator.] [type: integer]
.Tc Read-Only Job Attributes
.Ig
The following attributes are read-only, they are established by the server and are visible to the client but cannot be set by a client. Certain ones are only visible to privileged clients (those run by the batch administrator).
alt_id
.Ig
alt_id
.Ig For a few systems, such as Irix 6.x running Array Services, the session id is insufficient to track which processes belong to the job. Where a different identifier is required, it is recorded in this attribute. If set, it will also be recorded in the end-of-job accounting record.
For Irix 6.x running Array Services, the alt_id attribute is set to the Array Session Handle (ASH) assigned to the job. [internal type: string]
.Ig

.Ig The exit status of the job. This is only set on receipt of a job obituary notice from MOM, and probably only useful if the "keep_completed" server attribute is set. Note that negative values are generated internally by PBS to indicate system errors and are listed as the JOB_EXEC_* defines in pbs_job.h. Positive values are returned from the user script and cannot be interpreted by PBS. [internal type: integer]
.Ig
