DESCRIPTION
The
qstat
command is used to request the status of jobs, queues, or a batch server.
The requested status is written to standard out.
The status is obtained by sending a
Job Status ,
a
Queue Status ,
or a
Server Status
batch request to the appropriate server.
When requesting job status, synopsis format 1 or 2,
qstat
will output information about each
or all jobs at each
The capability to request status of all jobs at a destination is an extension
to POSIX 1003.2d.
Jobs for which the user does not have status privilege are not displayed.
When requesting queue or server status, synopsis format 3 through 5, qstat
will output information about each
The syntax using the [-a|-i|-r] line or the -q line are extensions to POSIX.
OPTIONS
- -f
- Specifies that a full status display be written to standard out.
- -a
- "All" jobs are displayed in the alternative format, see the Standard Output
section.
If the operand is a destination id, all jobs at that destination are displayed.
If the operand is a job id, information about that job is displayed.
- -i
- Job status is displayed in the alternative format.
For a destination id operand, status for jobs at that destination which are not
running are displayed.
This includeds jobs which are queued, held or waiting.
If an operand is a job id, status for that job is displayed regardless of its
state.
- -r
- If an operand is a job id, status for that job is displayed.
For a destination id operand, status for jobs at that destination which are
running are displayed, this includeds jobs which are suspended.
If an operand is a job id, status for that job is displayed.
- -n
- In addition to the basic information, nodes allocated to a job are listed.
- -s
- In addition to the basic information, any comment provided by the batch
administrator or scheduler is shown.
- -G
- Show size information in giga-bytes.
- -M
- Show size information, disk or memory in mega-words. A word is considered
to be 8 bytes.
- -R
- In addition to other information, disk reservation information is shown.
Not applicable to all systems.
- -u
- Job status is displayed in the alternative format. If an operand is a job id,
status for that job is displayed. For a destination id operand, status for
jobs at that destination which are owned by the user(s) listed in
are displayed.
The syntax of the
is:
Host names may be wild carded on the left end, e.g. "*.nasa.gov".
User_name without a "@host" is equivalent to "user_name@*", that is at any host.
- -Q
- Specifies that the request is for queue status and that the operands are
destination identifiers.
- -q
- Specifies that the request is for queue status which should be shown in
the alternative format.
- -B
- Specifies that the request is for batch server status and that the operands
are the names of servers.
OPERANDS
If neither the
nor the
option is given, the operands on the qstat
command must be either job identifiers or destinations identifiers.
If the operand is a job identifier, it must be in the following form:
where
is the job identifier assigned at submittal time, see
qsub.
If the
is omitted, the name of the default server will be used.
If
is supplied, the request will be for the job identifier currently at that
Server.
See ERS sections [Ji] and [Di] for more details on job identifiers and
batch destinations.
If the operand is a destination identifier, it is one of the following
three forms:
If
is specified, the request is for status of all jobs in that queue at the
default server. If the
form is given, the request is for status of all jobs at that server.
If a full destination identifier,
is given, the request is for status of all jobs in the named queue at the
named server.
If the
option is given, the operands are destination identifiers as specified
above. If
is specified, the status of that queue at the default server will be given.
If
is specified, the status of the named queue at the named server will be given.
If
is specified, the status of all queues at
the named server will be given.
If no destination is specified, the status of all queues at the default
server will be given.
If the
option is given, the operand is the name of a server.
STANDARD OUTPUT
Displaying Job Status
If job status is being displayed in the default format and the
option is not specified, the following items are displayed on a single
line, in the specified order, separated by white space:
- -
- the job identifier assigned by PBS.
- -
- the job name given by the submitter.
- -
- the job owner
- -
- the CPU time used
- -
- the job state:
E - Job is exiting after having run.
H - Job is held.
Q - job is queued, eligable to run or routed.
R - job is running.
T - job is being moved to new location.
W - job is waiting for its execution time
(-a option) to be reached.
S - (Unicos only) job is suspend.
This set of state letters does not conform to the POSIX 1003.2d standard.
It requires the sames letters, but in lower case.
- -
- the queue in which the job resides
If job status is being displayed and the
option is specified, the output will depend on whether
qstat
was compiled to use a
Tcl
interpreter. See the configuration section
for details. If
Tcl
is not being used,
full display for each job consists of the header line:
job identifier
Followed by one line per job attribute of the form:
The attribute name is indented 4 spaces. There is a single space on each side
of the equal sign. Long values wrap either at column 78 or following a comma
beyond which the next comma separated segment will not fit before column 79.
Continuation lines are indented by a tab (8 spaces).
There is blank line following the last attribute.
If any of the options -a, -i, -r, -u, -n, -s, -G or -M are provided,
the alternative display format for jobs is used.
The following items are displayed on a single
line, in the specified order, separated by white space:
- -
- the job identifier assigned by PBS.
- -
- the job owner.
- -
- The queue in which the job currently resides.
- -
- The job name given by the submitter.
- -
- The session id (if the job is running).

- Either the cpu time, if specified, or wall time requested by the job, (hh:mm).
- -
- The job's current state.
- -
- The amount of cpu time or wall time used by the job (hh:mm).
If the -R option is provied, the line contains:
- -
- the job identifier assigned by PBS.
- -
- the job owner.
- -
- The queue in which the job currently resides.
- -
- The number of nodes requested by the job.
- -
- The number of cpus or tasks requested by the job.
- -
- The amount of memory requested by the job.
- -
- Either the cpu time or wall time requested by the job.
- -
- The job's current state.
- -
- The amount of cpu time or wall time used by the job.
- -
- The amount of SRFS space requested on the big file sysstem.
- -
- The amount of SRFS space requested on the fast file sysstem.
- -
- The amount of space requested on the parallel I/O file system.
The last three fields may not contain useful information at all sites
or on all systems.
Displaying Queue Status
If queue status is being displayed and the
option was not specified, the following items are displayed on a single
line, in the specified order, separated by white space:
- -
- the queue name
- -
- the maximum number of jobs that may be run in the queue concurrently
- -
- the total number of jobs in the queue
- -
- the enable or disabled status of the queue
- -
- the started or stopped status of the queue
- -
- for each job state, the name of the state and the number of jobs in the queue
in that state.
- -
- the type of queue, execution or routing.
If queue status is being displayed and the
option is specified, the output will depend on whether
qstat
was compiled to use a
Tcl
interpreter. See the configuration section
for details. If
Tcl
is not being used,
the full display for each queue consists of the header line:
queue_name
Followed by one line per queue attribute of the form:
The queue attributes are listed in the same format as job attributes.
If the -q option is specified, queue information is displayed in the
alternative format: The following information is displayed on a single
line:
- -
- the queue name
- -
- the maximum amount of memory a job in the queue may request
- -
- the maximum amount of cpu time a job in the queue may request
- -
- the maximum amount of wall time a job in the queue may request
- -
- the maximum amount of nodes a job in the queue may request
- -
- the number of jobs in the queue in the running state

- the number of jobs in the queue in the queued state
- -
- the maximum number (limit) of jobs that may be run in the queue concurrently
- -
- the state of the queue given by a pair of letters:
- either the letter E if the queue is Enabled or D if Disabled, and
- either the letter R if the queue is Running (started) or S if Stopped.
Displaying Server Status
If batch server status is being displayed and the
option is not specified, the following items are displayed on a single

- -
- the total number of jobs currently managed by the server
- -
- the status of the server
- -
- for each job state, the name of the state and the number of jobs in the
server in that state
If server status is being displayed and the
option is specified, the output will depend on whether
qstat
was compiled to use a
Tcl
interpreter. See the configuration section
for details. If
Tcl
is not being used,
the full display for the server consist of the header line:
server name
Followed by one line per server attribute of the form:
The server attributes are listed in the same format as job attributes.
STANDARD ERROR
The qstat command will write a diagnostic message to standard error for
each error occurrence.
CONFIGURATION
If
qstat
is compiled with an option to include a
Tcl
interpreter, using the
flag to get a full display causes a check to be made for a script file
to use to output the requested information. The first location checked
is $HOME/.qstatrc. If this does not exist, the next location
checked is administrator configured. If one of these is found, a
Tcl
interpreter is started and the script file is passed to it along
with three global variables. The command line arguments
are split into two variable named
flags
and
operands .
The status information is passed in a variable named
objects .
All of these variables are
Tcl
lists.
The
flags
list contains the name of the command (usually "qstat") as its first
element. Any other elements are command line option flags with any
options they use, presented in the order given on the command line.
They are broken up individually so that if two flags are given
together on the command line, they are separated in the list.
For example, if the user typed
the
flags
list would contain
The
operands
list contains all other command line arguments following the flags.
There will always be at least one element in
operands
because if no operands are typed by the user, the default destination
or server name is used. The
objects
list contains all the information retrieved from the server(s)
so the Tcl interpreter can run once to format the entire output.
This list has the same number of elements as the
operands
list. Each element is another list with two elements. The first
element is a string giving the type of objects to be found in the
second. The string can take the values
"server", "queue", "job" or "error". The second element will be a
list in which each element is a single batch status object of the type given
by the string discussed above. In the case of "error", the list
will be empty. Each object is again a list.
The first element is the name of the object. The second is a list
of attributes. The third element will be the object text.
All three of these object elements corespond with fields in the structure
which is described in detail for each type of object by the man pages for
pbs_statjob(3), pbs_statque(3), and pbs_statserver(3).
Each attribute in the second element
list whose elements correspond with the
structure. Each will be a list with two elements. The first will be
the attribute name and the second will be the attribute value.
EXIT STATUS
Upon successful processing of all the operands presented to the
qstat command, the exit status will be a value of zero.
If the qstat command fails to process any operand, the
command exits with a value greater than zero.
