NAME
qselect - select queues.
SYNTAX
qselect [ -help ] [ -l resource=val,... ] [ -pe pe_name,... ] [ -q
wc_queue,... ] [ -s {r|p|s|z|hu|ho|hs|hj|ha|h}[+] ] [ -U user,... ]
DESCRIPTION
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.
OPTIONS
-help 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.
EXAMPLES
=====================================================
% 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
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 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.
SGE_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.
SGE_QMASTER_PORT
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.
