qdel-ge: delete Grid Engine jobs from queues

NAME

qdel - delete Grid Engine jobs from queues

SYNTAX

qdel [ -f ] [ -help ] [ -u wc_user_list ] [ wc_job_range_list ] [ -t task_id_range ]

DESCRIPTION

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. 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.

OPTIONS

-f

Force deletion of job(s). The job(s) are deleted from the list of jobs registered at even if the controlling the job(s) does not respond to the delete request sent by

Users which 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 However, behavior for administrative and non-administrative users differs. Jobs are deleted from the Grid Engine database immediately in 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

-help

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 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.

wc_job_range_list

A list of jobs, which should be deleted

ENVIRONMENTAL VARIABLES

GE_ROOT

Specifies the location of the Grid Engine standard configuration files.

GE_CELL

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 cell specified in the environment variable GE_CELL, if it is set.

The name of the default cell, i.e. default.

GE_DEBUG_LEVEL

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.

GE_QMASTER_PORT

If set, specifies the tcp port on which 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.
