qdel - delete 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 belonging 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. A manager using a job name or pattern 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(5).
- 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
Users who are neither 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, the behavior for administrative and non-administrative users differs. Jobs are deleted from the Grid Engine database immediately in the case of administrators. Otherwise, a regular deletion is attempted first and a forced cancellation is only executed 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.
- Deletes specified tasks of an array job. It means tasks created by the qsub -t command. For example, after creating an array job with the command "qsub -t 1-100 $SGE_ROOT/examples/sleeper.sh" it is possible to delete tasks 5-10 from the job array with the command "qdel job_id -t 5-10". All other tasks (1-4 and 11-100) will be executed.
- -u wc_user_list
- 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.
- Specifies the location of the Grid Engine standard configuration files.
- If set, specifies the default Grid Engine cell. To address a Grid Engine cell qdel uses (in the order of precedence):
The name of the default cell, i.e. default.
- 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 communication requests. Most installations will use a services map entry for the service "sge_qmaster" instead to define that port.
