pbs_queue_attributes - Man Page

Queue public attributes are alterable on request by a client.  The client must be acting for a user with administrator (manager) or operator privilege. Certain attributes require the user to have full administrator privilege before they can be modified. The following attributes apply to both queue types:

acl_group_enable

Attribute which when true directs the server to use the queue group access control list acl_groups . Format: boolean, "TRUE", "True", "true", "Y", "y", "1", "FALSE", "False", "false", "N", "n", "0"; default value: false = disabled.

acl_group_sloppy

Search a job user's secondary groups if the effective group doesn't match the group acl. Warning, this can be very slow and expensive. Format: boolean, "TRUE", "True", "true", "Y", "y", "1", "FALSE", "False", "false", "N", "n", "0"; default value: false = disabled.

acl_groups

List which allows or denies enqueuing of jobs owned by members of the listed groups.  The groups in the list are groups on the server host, not submitting hosts.  If acl_group_enable is set to true, only groups listed in the acl_groups attribute will be allowed access to the queue. See section 10.1, Authorization, in the PBS External Reference Specification. Format: "[+|-]group_name[,...]"; default value: all groups allowed.

acl_host_enable

Attribute which when true directs the server to use the acl_hosts access list. Format: boolean (see acl_group_enable); default value: disabled.

acl_hosts

List of hosts which may enqueue jobs in the queue. See section 10.1, Authorization, in the PBS External Reference Specification. Format: "[+|-]hostname[...]"; default value: all hosts allowed.

acl_logic_or

Modifies the way acls are applied if both acl_user_enable and acl_group_enable are set to true.  If acl_logic_or is true, then user and group acls are logically OR'ed together (a job can pass either the user or group acl lists to be allowed access to the queue).  If I acl_logic_or is false, then user and group acls are logically AND'ed together (a job would have to pass both user and group acl lists). Format: boolean (see acl_group_enable and acl_user_enable); default value: disabled.

acl_user_enable

Attribute which when true directs the server to use the the acl_users access list for this queue. Format: boolean (see acl_group_enable); default value: disabled.

acl_users

List of users allowed or denied the ability to enqueue jobs in this queue. See section 10.1, Authorization, in the PBS External Reference Specification.  If acl_user_enable is set to true, only users listed in the acl_groups attribute will be allowed access to the queue.

Format: "[+|-]user[@host][,...]"; default value: all users allowed.

disallowed_types

List of job "types" (interactive,batch,rerunable,nonrerunable,fault_tolerant,fault_intolerant) that are not allowed in this queue.

default value: all types allowed.

enabled

Queue will or will not accept new jobs.  When false the queue is disabled and will not accept jobs.  Format: boolean (see acl_group_enable); default value: disabled.

from_route_only

When true, this queue will not accept jobs except when being routed by the server from a local routing queue.  This is used to force user to submit jobs into a routing queue used to distribute jobs to other queues based on job resource limits.  Format: boolean; default value: disabled.

is_transit

When true, jobs will be allowed into this queue that do not fit server  resource limitations. This is to allow the jobs to be routed to a server that  does have the appropriate resources.  Any queue limits are checked.

max_queuable

The maximum number of jobs allowed to reside in the queue at any given time. Format: integer; default value: infinite.

max_user_queuable

The maximum number of jobs owned by a single user that are allowed to reside  in the queue at any given time. Format: integer; default value: infinite.

max_running

The maximum number of jobs allowed to be selected from this queue for routing or execution at any given time.  For a routing queue, this is enforced, if  set, by the server.  For an execution queue, this attribute is advisory to  the Scheduler, it is not enforced by the server.  Format: integer.

Priority

The priority of this queue against other queues of the same type on this server.  May affect job selection for execution/routing.  Advisory to the Scheduler, not used by the server.  Format: integer.

queue_type

The type of the queue: execution or route. Format: "execution", "e", "route", "r". This attribute must be explicitly set.

resources_max

The maximum amount of each resource which can be requested by a single job in this queue.  The queue value supersedes any server wide maximum limit. Format: "resources_max.resource_name=value", see qmgr(1B); default value: infinite usage.

resources_min

The minimum amount of each resource which can be requested by a single job in this queue. Format: see resources_max, default value: zero usage.

resources_default

The list of default resource values which are set as limits for a job  residing in this queue and for which the job did not specify a limit. Format: "resources_default.resource_name=value", see qmgr(1B); default value: none;  if not set, the default limit for a job is determined by the first of the following attributes which is set: server's resources_default, queue's resources_max, server's resources_max.  If none of these are set, the job will unlimited resource usage.

started 

Jobs may be scheduled for execution from this queue. When false, the queue is considered stopped. Advisory to the Scheduler, not enforced by the server. [default value: false, but depends on scheduler interpretation] Format: boolean (see acl_group_enable).

The following attributes apply only to execution queues:

checkpoint_defaults

Specifies the queues default checkpointing values to be used for a job that does not have any checkpointing specified.  Format: string; default value: none.

checkpoint_min

Specifies the minimum interval of cpu time, in minutes, which is allowed between checkpoints of a job.  If a user specifies a time less than this value, this value is used instead.  Format: integer; default value: no minimum.

resources_available

The list of resource and amounts available to jobs running in this queue. The sum of the resource of each type used by all jobs running from this queue cannot exceed the total amount listed here. Advisory to the Scheduler, not enforced by the server. Format: "resources_available.resource_name=value", see qmgr(1B).

keep_completed

Number of seconds to retain completed jobs in the C state.  This overrides the server attribute of the same name.  EXPERIMENTAL Format: integer; default value: 0.

kill_delay

The amount of the time delay between the sending of SIGTERM and SIGKILL when a qdel command is issued against a running job.  This overrides the server attribute of the same name. Format: integer seconds; default value: 2 seconds.

max_user_run

The maximum number of jobs owned by a single user that are allowed to be  running from this queue at one time.  This attribute is advisory to the Scheduler, it is not enforced by the server.  Format: integer; default value: none.

max_group_run

The maximum number of jobs owned by any users in a single group that are allowed to be running from this queue at one time. This attribute is advisory to the Scheduler, it is not enforced by the server. Format: integer; default value: none.

The following attributes apply only to routing queues:

route_destinations

The list of destinations to which jobs may be routed. [default value: none, should be set to at least one valid destination]

alt_router

If true, an site supplied, alternative job router function is used to determine the destination for routing jobs from this queue.  Otherwise, the default, round-robin router is used. Format: boolean (see acl_group_enable); default value: false.

route_held_jobs

If true, jobs with a hold type set may be routed from this queue.  If false, held jobs are not to be routed. Format: boolean (see acl_group_enable); default value: false.

route_waiting_jobs

If true, jobs with a future execution_time attribute may be routed from this queue.  If false, they are not to be routed. Format: boolean (see acl_group_enable); default value: false.

route_retry_time

Time delay between route retries.  Typically used when the network between servers is down.  Format: integer seconds; default value: {PBS_NET_RETRY_TIME} (30 seconds).

route_lifetime

The maximum time a job is allowed to exist in a routing queue.  If the job cannot be routed in this amount of time, the job is aborted. If unset or set to a value of zero (0), the lifetime is infinite. Format: integer seconds; default infinite.

The following data items are read-only attributes of the queue. They are visible to but cannot be changed by clients.

Items which apply to all types of queues are:

total_jobs

The number of jobs currently residing in the queue.

state_count

The total number of jobs currently residing in the queue in each state.

These read-only attributes only apply to execution queues:

resources_assigned

The total amount of certain types of resources allocated to jobs running from this queue.
