StandingReservation

This class represents a standing reservation.

A standing reservation is any reservation that is not a one-time reservation. This includes reservations that recur every day or every week, or infinite reservations.

Field Name Type Description
id String

The unique ID of the standing reservation.
access ReservationAccess

If set to ReservationAccess.SHARED, allows a standing reservation to use resources already allocated to other non-job reservations. Otherwise, these other reservations block resource access.
accounts Set<String>

Specifies that jobs with the associated accounts may use the resources contained within this reservation.

Specifies the user to which Moab will charge all idle cycles within the reservation (via the accounting manager).
Must be used in conjunction with chargeAccount
classes Set<String>

Specifies that jobs with the associated classes/queues may use the resources contained within this reservation.
clusters Set<String>

Specifies that jobs originating within the listed clusters may use the resources contained within this reservation.
comment String

flags Set<ReservationFlag>

Specifies special reservation attributes.
groups Set<String>

Specifies the groups allowed access to this standing reservation.
hosts Set<String>

Specifies the set of hosts that the scheduler can search for resources to satisfy the reservation. If specified using the class:X format, Moab only selects hosts that support the specified class. If TASKCOUNT is also specified, only TASKCOUNT tasks are reserved. Otherwise, all matching hosts are reserved.
jobAttributes Set<JobFlag>

Specifies job attributes that grant a job access to the reservation.
Values can be specified with a != assignment to only allow jobs NOT requesting a certain feature inside the reservation.
maxJob Integer

Specifies the maximum number of jobs that can run in the reservation.

Specifies the maximum time for jobs allowable. Can be used with affinity to attract jobs with same maxTime.
messages Set<String>

Messages associated with the reservation.
nodeFeatures Set<String>

Specifies the required node features for nodes that are part of the standing reservation.
os String

Specifies the operating system that should be in place during the reservation. Moab provisions this OS at reservation start and restores the original OS at reservation completion.
owner EmbeddedCredential

Specifies the owner of the reservation. Setting ownership for a reservation grants the user management privileges, including the power to release it.
Setting a user as the owner of a reservation gives that user privileges to query and release the reservation.
For sandbox reservations, sandboxes are applied to a specific peer only if owner is set to CLUSTER:<PEERNAME>
partition String

Specifies the partition in which to create the standing reservation. Defaults to ALL.
period TimeWindow

Period of the Standing reservation. Defaults to TimeWindow.DAY.

Specifies what resources constitute a single standing reservation task. (Each task must be able to obtain all of its resources as an atomic unit on a single node.)
Supported resources currently include the following:

  • PROCS (number of processors)
  • MEM (real memory in MB)
  • DISK (local disk in MB)
  • SWAP (virtual memory in MB)
rollbackOffset Integer

Specifies the minimum time in the future at which the reservation may start. This offset is rolling meaning the start time of the reservation will continuously roll back into the future to maintain this offset. Rollback offsets are a good way of providing guaranteed resource access to users under the conditions that they must commit their resources in the future or lose dedicated access. See QoS Credential in the Moab Workload Manager documentation for more information on quality of service and service level agreements.
startOffset Long

The starting offset, in seconds, from the beginning of the current period (DAY or WEEK), for this standing reservation. If period is DAY, the offset is from midnight (00:00) of the current day. If period is WEEK, the offset is from midnight Sunday of the current week.

Example 1: For a standing reservation that begins at 9:00 and ends at 17:00 every day, period is DAY, startOffset is 32400 (9*60*60), and endOffset is 61200 (17*60*60).

Example 2: For a standing reservation that begins at 9:00 Monday and ends at 17:00 Friday every week, period is WEEK, startOffset is 118800 ((24+9)*60*60), and endOffset is 493200 (((5*24)+17)*60*60).

Value Description
DEDICATED
SHARED

AclRule

This class represents a rule that can be in Moab's access control list (ACL) mechanism.

The basic AclRule information is the object's name and type. The type directly maps to an AclType value. The default mechanism Moab uses to check the ACL for a particular item is if the user or object coming in has ANY of the values in the ACL, then the user or object is given access. If no values match the user or object in question, the user or object is rejected access.

Field Name Type Description
affinity AclAffinity

Reservation ACLs allow or deny access to reserved resources but they may also be configured to affect a job's affinity for a particular reservation. By default, jobs gravitate toward reservations through a mechanism known as positive affinity. This mechanism allows jobs to run on the most constrained resources leaving other, unreserved resources free for use by other jobs that may not be able to access the reserved resources. Normally this is a desired behavior. However, sometimes, it is desirable to reserve resources for use only as a last resort-using the reserved resources only when there are no other resources available. This last resort behavior is known as negative affinity.

Defaults to AclAffinity.POSITIVE.
comparator ComparisonOperator

The type of comparison to make against the ACL object.

Defaults to ComparisonOperator.EQUAL.
type AclType

The type of the object that is being granted (or denied) access.
value String

The name of the object that is being granted (or denied) access.

AclAffinity

This enumeration describes the values available for describing how a rule is used in establishing access to an object in Moab. Currently, these ACL affinities are used only for granting access to reservations.

Value Description
NEGATIVE Access to the object is repelled using this rule until access is the last choice.
NEUTRAL Access to the object is not affected by affinity.
POSITIVE Access to the object is looked at as the first choice.
PREEMPTIBLE Access to the object given the rule gives preemptible status to the accessor. Supported only during GET.
REQUIRED The rule in question must be satisified in order to gain access to the object. Supported only during GET.
UNAVAILABLE The rule does not have its affinity available. Supported only during GET.

ComparisonOperator

This enumeration is used when Moab needs to compare items. One such use is in Access Control Lists (ACLs).

Value Description
GREATER_THAN Valid values: ">", "gt"
GREATER_THAN_OR_EQUAL Valid values: ">=", "ge"
LESS_THAN Valid values: "<", "lt"
LESS_THAN_OR_EQUAL Valid values: "<=", "le"
EQUAL Valid values: "==", "eq", "="
NOT_EQUAL Valid values: "!=", "ne", "<>"
LEXIGRAPHIC_SUBSTRING Valid value: "%<"
LEXIGRAPHIC_NOT_EQUAL Valid value: "%!"
LEXIGRAPHIC_EQUAL Valid value: "%="

Reservation

A reservation is the mechanism by which Moab guarantees the availability of a set of resources at a particular time. Each reservation consists of three major components: (1) a set of resources, (2) a time frame, and (3) an access control list. It is a scheduler role to ensure that the access control list is not violated during the reservation's lifetime (that is, its time frame) on the resources listed. For example, a reservation may specify that node002 is reserved for user Tom on Friday. The scheduler is thus constrained to make certain that only Tom's jobs can use node002 at any time on Friday.

RESET_ON_MODIFY The trigger resets if the object it is attached to is modified, even if multifire is not set.
SOFT_KILL By default, a SIGKILL (kill -9) signal is sent to the kill the script when a trigger times out. This flag will instead send a SIGTERM (kill -15) signal to kill the script. The SIGTERM signal will allow the script to trap the signal so that the script can clean up any residual information on the system (instead of just dying, as with the SIGKILL signal).

NOTE: A timed-out trigger will only receive one kill signal. This means that if you specify this flag, a timed-out trigger will only receive the SIGTERM signal, and never the SIGKILL signal.

rollbackOffset Integer

Specifies the minimum time in the future at which the reservation may start. This offset is rolling meaning the start time of the reservation will continuously roll back into the future to maintain this offset. Rollback offsets are a good way of providing guaranteed resource access to users under the conditions that they must commit their resources in the future or lose dedicated access. See QoS Credential in the Moab Workload Manager documentation for more information on quality of service and service level agreements.

SHARED

AclRule

This class represents a rule that can be in Moab's access control list (ACL) mechanism.

The basic AclRule information is the object's name and type. The type directly maps to an AclType value. The default mechanism Moab uses to check the ACL for a particular item is if the user or object coming in has ANY of the values in the ACL, then the user or object is given access. If no values match the user or object in question, the user or object is rejected access.

Field Name Type Description
affinity AclAffinity

Reservation ACLs allow or deny access to reserved resources but they may also be configured to affect a job's affinity for a particular reservation. By default, jobs gravitate toward reservations through a mechanism known as positive affinity. This mechanism allows jobs to run on the most constrained resources leaving other, unreserved resources free for use by other jobs that may not be able to access the reserved resources. Normally this is a desired behavior. However, sometimes, it is desirable to reserve resources for use only as a last resort-using the reserved resources only when there are no other resources available. This last resort behavior is known as negative affinity.

Defaults to AclAffinity.POSITIVE.
comparator ComparisonOperator

The type of comparison to make against the ACL object.

Defaults to ComparisonOperator.EQUAL.
type AclType

The type of the object that is being granted (or denied) access.
value String

The name of the object that is being granted (or denied) access.

AclAffinity

This enumeration describes the values available for describing how a rule is used in establishing access to an object in Moab. Currently, these ACL affinities are used only for granting access to reservations.

Value Description
NEGATIVE Access to the object is repelled using this rule until access is the last choice.
NEUTRAL Access to the object is not affected by affinity.
POSITIVE Access to the object is looked at as the first choice.
PREEMPTIBLE Access to the object given the rule gives preemptible status to the accessor. Supported only during GET.
REQUIRED The rule in question must be satisified in order to gain access to the object. Supported only during GET.
UNAVAILABLE The rule does not have its affinity available. Supported only during GET.

ComparisonOperator

This enumeration is used when Moab needs to compare items. One such use is in Access Control Lists (ACLs).

Value Description
GREATER_THAN Valid values: ">", "gt"
GREATER_THAN_OR_EQUAL Valid values: ">=", "ge"
LESS_THAN Valid values: "<", "lt"
LESS_THAN_OR_EQUAL Valid values: "<=", "le"
EQUAL Valid values: "==", "eq", "="
NOT_EQUAL Valid values: "!=", "ne", "<>"
LEXIGRAPHIC_SUBSTRING Valid value: "%<"
LEXIGRAPHIC_NOT_EQUAL Valid value: "%!"
LEXIGRAPHIC_EQUAL Valid value: "%="

Reservation

A reservation is the mechanism by which Moab guarantees the availability of a set of resources at a particular time. Each reservation consists of three major components: (1) a set of resources, (2) a time frame, and (3) an access control list. It is a scheduler role to ensure that the access control list is not violated during the reservation's lifetime (that is, its time frame) on the resources listed. For example, a reservation may specify that node002 is reserved for user Tom on Friday. The scheduler is thus constrained to make certain that only Tom's jobs can use node002 at any time on Friday.

RESET_ON_MODIFY The trigger resets if the object it is attached to is modified, even if multifire is not set.
SOFT_KILL By default, a SIGKILL (kill -9) signal is sent to the kill the script when a trigger times out. This flag will instead send a SIGTERM (kill -15) signal to kill the script. The SIGTERM signal will allow the script to trap the signal so that the script can clean up any residual information on the system (instead of just dying, as with the SIGKILL signal).

NOTE: A timed-out trigger will only receive one kill signal. This means that if you specify this flag, a timed-out trigger will only receive the SIGTERM signal, and never the SIGKILL signal.
