qdel - delete Sun Grid Engine jobs from queues
qdel [ -f ] [ -help ] [ -u wc_user_list ] [
wc_job_range_list ] [ -t task_id_range ]
Qdel provides a means for a user/operator/manager to delete
one or more jobs. A manager/operator can delete jobs belong-
ing to any user, while a regular user can only delete his or
her own jobs. If a manager wants to delete another user's
job, the manager can specify the job id. If the manager is
using a job name or pattern, he or she must also specify the
user's name via "-u wc_user_list". A "qdel wc_job_name" will
delete only the jobs of the calling user by default. Qdel
deletes jobs in the order in which their job identifiers are
presented. Find additional information concerning
wc_user_list and wc_job_list in sge_types(1).
-f Force deletion of job(s). The job(s) are deleted from
the list of jobs registered at sge_qmaster(8) even if
the sge_execd(8) controlling the job(s) does not
respond to the delete request sent by sge_qmaster(8).
Users which are neither Sun Grid Engine managers nor
operators can only use the -f option (for their own
jobs) if the cluster configuration entry qmaster_params
contains the flag ENABLE_FORCED_QDEL (see sge_conf(5)).
However, behavior for administrative and non-
administrative users differs. Jobs are deleted from the
Sun Grid Engine database immediately in case of
administrators. Otherwise, a regular deletion is
attempted first and a forced cancellation is only exe-
cuted if the regular deletion was unsuccessful.
Additionally regular qdel requests can result in a
forced deletion of a job if
ENABLE_FORCED_QDEL_IF_UNKNOWN is set in the
qmaster_params (see sge_conf(5))
Prints a listing of all options.
-t Deletes specified tasks of array job. It means tasks
created by qsub -t command. For example after creating
array job by command "qsub -t 1-100
$SGE_ROOT/examples/sleeper.sh" it is possible to delete
tasks 5-10 from job array by command "qdel job_id -t
5-10". All other tasks (1-4 and 11-100) will be exe-
Deletes only those jobs which were submitted by users
specified in the list of usernames. For managers it is
possible to use qdel -u "*" to delete all jobs of all
users. If a manager wants to delete a specific job of a
user, he has to specify the user and the job. If no job
is specified all jobs from that user are deleted.
A list of jobs, which should be deleted
SGE_ROOT Specifies the location of the Sun Grid Engine
standard configuration files.
SGE_CELL If set, specifies the default Sun Grid Engine
cell. To address a Sun Grid Engine cell qdel
uses (in the order of precedence):
The name of the cell specified in the
environment variable SGE_CELL, if it is
The name of the default cell, i.e.
If set, specifies that debug information
should be written to stderr. In addition the
level of detail in which debug information is
generated is defined.
If set, specifies the tcp port on which
sge_qmaster(8) is expected to listen for com-
munication requests. Most installations will
use a services map entry for the service
"sge_qmaster" instead to define that port.
