This section lists the following queue attributes:
This section also lists some queue resource limits (see Assigning queue resource limits).
For Boolean attributes, T, t, 1, Y, and y are all synonymous with "TRUE," and F, f, 0, N, and n all mean "FALSE."
| acl_groups | |
|---|---|
| Format | <GROUP>[@<HOST>][+<USER>[@<HOST>]]... |
| Default | --- |
| Description |
Specifies the list of groups which may submit jobs to the queue. If acl_group_enable is set to true, only users with a primary group listed in acl_groups may utilize the queue.
If the PBSACLUSEGROUPLIST variable is set in the pbs_server environment, acl_groups checks against all groups of which the job user is a member. |
| Example |
> qmgr -c "set queue batch acl_groups=staff"
Used in conjunction with acl_group_enable. |
| acl_group_enable | |
|---|---|
| Format | <BOOLEAN> |
| Default | FALSE |
| Description | If TRUE, constrains TORQUE to only allow jobs submitted from groups specified by the acl_groups parameter. |
| Example | qmgr -c "set queue batch acl_group_enable=true" |
| acl_group_sloppy | |
|---|---|
| Format | <BOOLEAN> |
| Default | FALSE |
| Description | If TRUE, acl_groups will be checked against all groups of which the job users is a member. |
| Example | --- |
| acl_hosts | |

qmgr -c "set queue batch acl_hosts=h1+h2+h3"
Used in conjunction with acl_host_enable. |
| acl_host_enable | |
|---|---|
| Format | <BOOLEAN> |

Used in conjunction with acl_user_enable. |
| acl_user_enable | |
|---|---|
| Format | <BOOLEAN> |
| Default | FALSE |

| Default | 0 |
| Description | Specifies the priority value associated with the queue. |
| Example | qmgr -c "set queue batch priority=20" |
| queue_type | |
|---|---|
| Format | One of e, execution, r, or route (see Creating a routing queue) |
| Default | --- |
| Description |
Specifies the queue type. 
This value must be explicitly set for all queues. |

<queue>[@<host>] |
| Default | --- |
| Description |
Specifies the potential destination queues for jobs submitted to the associated routing queue.
This attribute is only valid for routing queues (see Creating a routing queue). |

To set multiple queue specifications, use multiple commands: > qmgr -c 's s route_destinations=batch'
|
| started | |
|---|---|
| Format | <BOOLEAN> |
| Default | FALSE |
| Description | Specifies whether jobs in the queue are allowed to execute. |
| Example | qmgr -c "set queue batch started=true" |
Resources may include one or more of the following: arch, mem, nodes, ncpus, nodect, procct, pvmem, and walltime.
Assigning queue resource limits
Administrators can use resources limits to help direct what kind of jobs go to different queues. There are four queue attributes where resource limits can be set: resources_available, resources_default, resources_max, and resources_min. The list of supported resources that can be limited with these attributes are arch, mem, ncpus, nodect, nodes, procct, pvmemvmem, and walltime.
| Resource | Format | Description |
|---|---|---|
| arch | string | Specifies the administrator defined system architecture required. |
| mem | size | Amount of physical memory used by the job. (Ignored on Darwin, Digital Unix, Free BSD, HPUX 11, IRIX, NetBSD, and SunOS. Also ignored on Linux if number of nodes is not 1. Not implemented on AIX and HPUX 10.) |
| ncpus | integer | An artifact of job centric mode is that if a job does not have an attribute set, the server and routing queue defaults are not applied when queue resource limits are checked. Consequently, a job that requests 32 nodes (not ncpus=32) will not be checked against a min_resource.ncpus limit. |
| nodect | integer | Sets the number of nodes available. By default, TORQUE will set the number of nodes available to the number of nodes listed in the $TORQUE_HOME/server_priv/nodes file. nodect can be set to be greater than or less than that number. Generally, it is used to set the node count higher than the number of physical nodes in the cluster. |
| nodes | integer | Specifies the number of nodes. |
| procct | integer |
Sets limits on the total number of execution slots (procs) allocated to a job. The number of procs is calculated by summing the products of all node and ppn entries for a job. For example qsub -l nodes=2:ppn=2+3:ppn=4 job.sh would yield a procct of 16. 2*2 (2:ppn=2) + 3*4 (3:ppn=4). |
| pvmem | size | Amount of virtual memory used by any single process in a job. |
| vmem | size | Amount of virtual memory used by all concurrent processes in the job. |
| walltime | seconds, or [[HH:]MM:]SS | Amount of real time during which a job can be in a running state. |
The size format specifies the maximum amount in terms of bytes or words. It is expressed in the form integer[suffix]. The suffix is a multiplier defined in the following table ("b" means bytes [the default] and "w" means words). The size of a word is calculated on the execution server as its word size.
| Suffix | Multiplier | |
|---|---|---|
| b | w | 1 |
| kb | kw | 1024 |
| mb | mw | 1,048,576 |
| gb | gw | 1,073,741,824 |
| tb | tw | 1,099,511,627,776 |
