NAME
qstat - Displays the status of NQS requests and queues.
SYNOPSIS
qstat [ -a | -U ] [ -b ] [ -d ] [ -f | -l ] [ -h hostname ]
[ -n ] [ -p ] [ -s state ]
[ -t n_days queue ] [ -u user ] [ queue ... ] [ queue@host
... ] [ -v ]
DESCRIPTION OF PARAMETERS
-a Displays the status of requests belonging to all
users.
-b Displays batch queues.
-d Displays device queues.
-f Shows queues or requests in a full format, that
is, multiple lines for each request or queue. The
default listing shows one line for each request or
queue.
-h host-name
Displays requests for queues on the host-name
host.
-l Same as -f.
-n The queue header and trailer are not displayed.
-p Displays pipe queues.
-s state Displays only those requests with the specified
state.
Allowable states are:
r Running
h Holding
q Queued
t Exiting
-t n_days queue
(Currently unused.) Displays the tennis court
schedule for a dedicated request up to 7 days in
advance. The n_day is an integer from 0 to 6,
where 0 is the current day. If a 0 is specified,
the available time slot will be listed. If an
integer n from 1 to 6 is specified, the available
time slots for the day which is n days in advance
of the current day will be listed.
-u user Shows only those requests belonging to the
specified user. By default, qstat shows requests
belonging to the invoking user.
-U Same as -a.
-v Displays output in 132-column format, and adds a
NODES field (number of nodes associated with a
request) and a SUBMITTED AT field (date and time
the request was submitted) to the standard
display.
queue ...
The name of a queue for which the status is being
requested. The local host is assumed if it is not
indicated with the @host specifier.
queue@host ...
The name of a queue for which the status is being
requested. The host named host is indicated.
DISCUSSION
The qstat command displays the status of NQS requests and
queues. In the absence of -a, -u, or -U, qstat shows only
requests and queues belonging to the user who executes it.
If no options are specified, NQS displays the current state
of each NQS request on the local host. Otherwise, the type
of information displayed is determined by the invocation
flag used.
qstat displays information about each selected queue. The
flags can be used to display particular types of
information.
If information about the queues is requested with the -b,
-d, or -p flags, but no queues are specified, then the
current state of each NQS queue on the local host is
displayed. Otherwise, information is displayed for the
specified queues only. Queues may be specified either as
queue-name or queue-name@host-name. In the absence of a
host-name specifier, the local host is assumed. You must
have an account on the host specified in order for qstat to
work. Also, root use of qstat is limited to the local
machine.
When a queue is being examined, the queue name, host
machine, priority, number of requests in a given state,
resource limits, and access are displayed.
QUEUE STATE
The general state of a queue is defined by two principal
properties of the queue.
The first property determines whether or not requests can be
submitted to the queue. If they can, then the queue is said
to be enabled. Otherwise the queue is said to be disabled.
The second principal property of a queue determines if
requests which are ready to run, but are not now presently
running, will be allowed to run upon the completion of any
currently running requests, and whether any requests are
presently running in the queue.
If queued requests not already running are blocked from
running, and no requests are presently executing in the
queue, then the queue is said to be stopped. If the same
situation exists with the difference that at least one
request is running, then the queue is said to be stopping,
where the requests presently executing will be allowed to
complete execution, but no new requests will be spawned.
One of the words AVAILABLE, STOPPED, DISABLED, UNAVAIL, or
NQS DOWN will appear in the queue status field to indicate
the respective queue states of:
AVAILABLE Enabled and started.
STOPPED Enabled and stopped.
DISABLED Disabled and started.
UNAVAIL Disabled and stopped.
Requests can only be submitted to the queue if the queue is
enabled, and the local NQS daemon is present.
If the NQS daemon for the local host upon which the queue
resides is not running, the status displays NQS DOWN.
CAVEATS
The -s flag currently gives incorrect results.
