qselect — select queues.


qselect [ -help ] [ -l resource=val,... ] [ -pe pe_name,... ] [ -q wc_queue,... ] [ -s {r|p|s|z|hu|ho|hs|hj|ha|h}[+] ] [ -U user,... ]


qselect prints a list of Sun Grid Engine queue names corresponding to  selection criteria specified in the qselect arguments described below. The output of qselect can be fed into other Sun Grid Engine commands to apply  actions on the selected queue sets. For example together with the -mqattr option to qconf(1), qselect can be used to modify queue attributes on a set of queues.



Prints a listing of all options.

-l resource[=value],...

Defines the resources to be granted by the queues which should be  included in the queue list output. Matching is performed on  queues based on non-mutable resource availability information only.  That means load values are always ignored except the so-called static  load values (i.e. "arch", "num_proc", "mem_total", "swap_total" and  "virtual_total") ones. Also consumable utilization is ignored. If there are multiple -l resource requests they will be concatenated by a logical AND: a queue needs to offer all resources to be displayed.

-pe pe_name,...

Includes queues into the output which are attached to at least one of the  parallel environments enlisted in the comma separated option argument.

-q wc_queue,...

Directly specifies the wildcard expression queue list to be included in the output.  This option usually is only meaningful in conjunction with another qselect option to extract a subset of queue names from a list given by -q. Description of wc_queue can be found in sge_types(1).

-qs {a|c|d|o|s|u|A|C|D|E|S}

This option allows to filter for queue instances in certain states.

-U user,...

Includes the queues to which the specified users have access in the qselect output.



% qselect -l arch=linux
% qselect -l arch=linux -U andreas,shannon
% qconf -mattr queue h_vmem=1GB `qselect -l arch=linux`


The first example prints the names of those queues residing on Linux  machines. The second command in addition restricts the output to those  queues with access permission for the users andreas and shannon. The third command changes the queue attribute h_vmem to 1 Gigabyte on queues residing on Linux machines (see the qconf(1) manual page for details on the -mattr option and the queue_conf(5) manual page on details of queue configuration entries).

Environmental Variables


Specifies the location of the Sun Grid Engine standard configuration files.


If set, specifies the default Sun Grid Engine cell. To address a Sun Grid Engine cell qselect uses (in the order of precedence):

The name of the cell specified in the environment  variable SGE_CELL, if it is set.

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.
