sacctmgr - Man Page

Used to view and modify Slurm account information.

Examples (TL;DR)

Synopsis

sacctmgr [Options...] [COMMAND...]

Description

sacctmgr is used to view or modify Slurm account information. The account information is maintained within a database with the interface being provided by slurmdbd (Slurm Database daemon). This database can serve as a central storehouse of user and computer information for multiple computers at a single site. Slurm account information is recorded based upon four parameters that form what is referred to as an association. These parameters are user, cluster, partition, and account. user is the login name. cluster is the name of a Slurm managed cluster as specified by the ClusterName parameter in the slurm.conf configuration file. partition is the name of a Slurm partition on that cluster. account is the bank account for a job. The intended mode of operation is to initiate the sacctmgr command, add, delete, modify, and/or list association records then commit the changes and exit.

NOTE: The contents of Slurm's database are maintained in lower case. This may result in some sacctmgr output differing from that of other Slurm commands.

Options

-s,  --associations

Use with show or list to display associations with the entity. This is equivalent to the associations command.

-h,  --help

Print a help message describing the usage of sacctmgr. This is equivalent to the help command.

-i,  --immediate

Commit changes immediately without asking for confirmation.

-n,  --noheader

No header will be added to the beginning of the output.

-p,  --parsable

Output will be '|' delimited with a '|' at the end.

Output will be '|' delimited without a '|' at the end.

-Q,  --quiet

Print no messages other than error messages. This is equivalent to the quiet command.

-r,  --readonly

Makes it so the running sacctmgr cannot modify accounting information. The readonly option is for use within interactive mode.

-v,  --verbose

Enable detailed logging. This is equivalent to the verbose command.

-V , --version

Display version number. This is equivalent to the version command.

exit

Terminate sacctmgr interactive mode. Identical to the quit command.

quiet

Print no messages other than error messages.

quit

Terminate the execution of sacctmgr interactive mode. Identical to the exit command.

verbose

Entities

account

A bank account, typically specified at job submit time using the --account= option. These may be arranged in a hierarchical fashion, for example accounts 'chemistry' and 'physics' may be children of the account 'science'. The hierarchy may have an arbitrary depth.

association

The entity used to group information consisting of four parameters: account, cluster, partition (optional), and user. Used only with the list or show command.  Add, modify, and delete should be done to a user, account or cluster entity, which will in turn update the underlying associations. Modification of attributes like limits is allowed for an association but not a modification of the four core attributes of an association. You cannot change the partition setting (or set one if it has not been set) for an existing association. Instead, you will need to create a new association with the partition included. You can either keep the previous association with no partition defined, or delete it. Note that these newly added associations are unique entities and any existing usage information will not be carried over to the new association.

cluster

The ClusterName parameter in the slurm.conf configuration file, used to differentiate accounts on different machines.

configuration

Used only with the list or show command to report current system configuration.

coordinator

A special privileged user, usually an account manager, that can add users or sub-accounts to the account they are coordinator over. This should be a trusted person since they can change limits on account and user associations, as well as cancel, requeue or reassign accounts of jobs inside their realm.

event

Events like downed or draining nodes on clusters.

federation

A group of clusters that work together to schedule jobs.

job

Used to modify specific fields of a job: Derived Exit Code, Comment, AdminComment, SystemComment, or WCKey.

problem

Use with show or list to display entity problems.

qos

Quality of Service.

reservation

A collection of resources set apart for use by a particular account, user or group of users for a given period of time.

resource

Software resources for the system. Those are software licenses shared among clusters.

RunawayJobs

Used only with the list or show command to report current jobs that have been orphaned on the local cluster and are now runaway.  If there are jobs in this state it will also give you an option to "fix" them. NOTE: You must have an AdminLevel of at least Operator to perform this.

stats

Used with list or show command to view server statistics. Accepts optional argument of ave_time or total_time to sort on those fields. By default, sorts on increasing RPC count field.

transaction

List of transactions that have occurred during a given time period.

tres

Used with list or show command to view a list of Trackable RESources configured on the system.

user

The login name. Usernames are case-insensitive (forced to lowercase) unless the PreserveCaseUser option has been set in the SlurmDBD configuration file.

wckeys

Workload  Characterization  Key. An arbitrary  string  for  grouping orthogonal accounts.

General Specifications for Association Based Entities

NOTE: The group limits (GrpJobs, GrpTRES, etc.) are tested when a job is being considered for being allocated resources. If starting a job would cause any of its group limit to be exceeded, that job will not be considered for scheduling even if that job might preempt other jobs which would release sufficient group resources for the pending job to be initiated.

DefaultQOS=<default_qos>

The default QOS this association and its children should have. This is overridden if set directly on a user. To clear a previously set value use the modify command with a new value of -1.

Fairshare={<fairshare_number>|parent}
Share={<fairshare_number>|parent}

Number used in conjunction with other accounts to determine job priority. Can also be the string parent, when used on a user this means that the parent association is used for fairshare.  If Fairshare=parent is set on an account, that account's children will be effectively reparented for fairshare calculations to the first parent of their parent that is not Fairshare=parent.  Limits remain the same, only its fairshare value is affected.  To clear a previously set value use the modify command with a new value of -1.

GrpJobs=<max_jobs>

Maximum number of running jobs in aggregate for this association and all associations which are children of this association. To clear a previously set value use the modify command with a new value of -1.

GrpJobsAccrue=<max_jobs>

Maximum number of pending jobs in aggregate able to accrue age priority for this association and all associations which are children of this association. To clear a previously set value use the modify command with a new value of -1.

GrpSubmit=<max_jobs>
GrpSubmitJobs=<max_jobs>

Maximum number of jobs which can be in a pending or running state at any time in aggregate for this association and all associations which are children of this association. To clear a previously set value use the modify command with a new value of -1.

GrpTRES=TRES=<max_TRES>[,TRES=<max_TRES>,...]

Maximum number of TRES running jobs are able to be allocated in aggregate for this association and all associations which are children of this association. To clear a previously set value use the modify command with a new value of -1 for each TRES id.

NOTE: This limit only applies fully when using the Select Consumable Resource plugin.

GrpTRESMins=TRES=<minutes>[,TRES=<minutes>,...]

The total number of TRES minutes that can possibly be used by past, present and future jobs running from this association and its children. To clear a previously set value use the modify command with a new value of -1 for each TRES id.

NOTE: This limit is not enforced if set on the root association of a cluster.  So even though it may appear in sacctmgr output, it will not be enforced.

ALSO NOTE: This limit only applies when using the Priority Multifactor plugin.  The time is decayed using the value of PriorityDecayHalfLife or PriorityUsageResetPeriod as set in the slurm.conf.  When this limit is reached all associated jobs running will be killed and all future jobs submitted with associations in the group will be delayed until they are able to run inside the limit.

GrpTRESRunMins=TRES=<minutes>[,TRES=<minutes>,...]

Used to limit the combined total number of TRES minutes used by all jobs running with this association and its children.  This takes into consideration time limit of running jobs and consumes it, if the limit is reached no new jobs are started until other jobs finish to allow time to free up.

GrpWall=<max_wall>

Maximum wall clock time running jobs are able to be allocated in aggregate for this association and all associations which are children of this association. To clear a previously set value use the modify command with a new value of -1.

NOTE: This limit is not enforced if set on the root association of a cluster.  So even though it may appear in sacctmgr output, it will not be enforced.

ALSO NOTE: This limit only applies when using the Priority Multifactor plugin.  The time is decayed using the value of PriorityDecayHalfLife or PriorityUsageResetPeriod as set in the slurm.conf.  When this limit is reached all associated jobs running will be killed and all future jobs submitted with associations in the group will be delayed until they are able to run inside the limit.

MaxJobs=<max_jobs>

Maximum number of jobs each user is allowed to run at one time in this association. This is overridden if set directly on a user. Default is the cluster's limit. To clear a previously set value use the modify command with a new value of -1.

MaxJobsAccrue=<max_jobs>

Maximum number of pending jobs able to accrue age priority at any given time for the given association. This is overridden if set directly on a user. Default is the cluster's limit. To clear a previously set value use the modify command with a new value of -1.

MaxSubmit=<max_jobs>
MaxSubmitJobs=<max_jobs>

Maximum number of jobs which this association can have in a pending or running state at any time. Default is the cluster's limit. To clear a previously set value use the modify command with a new value of -1.

MaxTRESMins=TRES=<minutes>[,TRES=<minutes>,...]
MaxTRESMinsPerJob=TRES=<minutes>[,TRES=<minutes>,...]

Maximum number of TRES minutes each job is able to use in this association. This is overridden if set directly on a user. Default is the cluster's limit. To clear a previously set value use the modify command with a new value of -1 for each TRES id.

MaxTRES=TRES=<max_TRES>[,TRES=<max_TRES>,...]
MaxTRESPerJob=TRES=<max_TRES>[,TRES=<max_TRES>,...]

Maximum number of TRES each job is able to use in this association. This is overridden if set directly on a user. Default is the cluster's limit. To clear a previously set value use the modify command with a new value of -1 for each TRES id.

NOTE: This limit only applies fully when using cons_res or cons_tres select type plugins.

MaxWall=<max_wall>
MaxWallDurationPerJob=<max_wall>

Maximum wall clock time each job is able to use in this association. This is overridden if set directly on a user. Default is the cluster's limit. <max wall> format is <min> or <min>:<sec> or <hr>:<min>:<sec> or <days>-<hr>:<min>:<sec> or <days>-<hr>. The value is recorded in minutes with rounding as needed. To clear a previously set value use the modify command with a new value of -1.

NOTE: Changing this value will have no effect on any running or pending job.

Priority

What priority will be added to a job's priority when using this association. This is overridden if set directly on a user. Default is the cluster's limit. To clear a previously set value use the modify command with a new value of -1.

QosLevel<operator><comma_separated_list_of_qos_names>

Specify the default Quality of Service's that jobs are able to run at for this association.  To get a list of valid QOS's use 'sacctmgr list qos'. This value will override its parents value and push down to its children as the new default.  Setting a QosLevel to '' (two single quotes with nothing between them) restores its default setting.  You can also use the operator += and -= to add or remove certain QOS's from a QOS list.

Valid <operator> values include:

=

Set QosLevel to the specified value. Note: the QOS that can be used at a given account in the hierarchy are inherited by the children of that account. By assigning QOS with the = sign only the assigned QOS can be used by the account and its children.

+=

Add the specified <qos> value to the current QosLevel. The account will have access to this QOS and the other previously assigned to it.

-=

Remove the specified <qos> value from the current QosLevel.

Specifications for QoS

NOTE: The group limits (GrpJobs, GrpNodes, etc.) are tested when a job is being considered for being allocated resources. If starting a job would cause any of its group limit to be exceeded, that job will not be considered for scheduling even if that job might preempt other jobs which would release sufficient group resources for the pending job to be initiated.

Flags

Used by the slurmctld to override or enforce certain characteristics.
Valid options are

DenyOnLimit

If set, jobs using this QOS will be rejected at submission time if they do not conform to the QOS 'Max' or 'Min' limits as stand-alone jobs. Jobs that exceed these limits when other jobs are considered, but conform to the limits when considered individually will not be rejected. Instead they will pend until resources are available. Group limits (e.g. GrpTRES) will also be treated like 'Max' limits (e.g. MaxTRESPerNode) and jobs will be denied if they would violate the limit as stand-alone jobs. This currently only applies to QOS and Association limits.

EnforceUsageThreshold

If set, and the QOS also has a UsageThreshold, any jobs submitted with this QOS that fall below the UsageThreshold will be held until their Fairshare Usage goes above the Threshold.

NoDecay

If set, this QOS will not have its GrpTRESMins, GrpWall and UsageRaw decayed by the slurm.conf PriorityDecayHalfLife or PriorityUsageResetPeriod settings.  This allows a QOS to provide aggregate limits that, once consumed, will not be replenished automatically.  Such a QOS will act as a time-limited quota of resources for an association that has access to it.  Account/user usage will still be decayed for associations using the QOS.  The QOS GrpTRESMins and GrpWall limits can be increased or the QOS RawUsage value reset to 0 (zero) to again allow jobs submitted with this QOS to be queued (if DenyOnLimit is set) or run (pending with QOSGrp{TRES}MinutesLimit or QOSGrpWallLimit reasons, where {TRES} is some type of trackable resource).

NoReserve

If this flag is set and backfill scheduling is used, jobs using this QOS will not reserve resources in the backfill schedule's map of resources allocated through time. This flag is intended for use with a QOS that may be preempted by jobs associated with all other QOS (e.g use with a "standby" QOS). If this flag is used with a QOS which can not be preempted by all other QOS, it could result in starvation of larger jobs.

OverPartQOS

If set jobs using this QOS will be able to override any limits used by the requested partition's QOS limits.

PartitionMaxNodes

If set jobs using this QOS will be able to override the requested partition's MaxNodes limit.

PartitionMinNodes

If set jobs using this QOS will be able to override the requested partition's MinNodes limit.

PartitionTimeLimit

If set jobs using this QOS will be able to override the requested partition's TimeLimit.

RequiresReservation

If set jobs using this QOS must designate a reservation when submitting a job. This option can be useful in restricting usage of a QOS that may have greater preemptive capability or additional resources to be allowed only within a reservation.

UsageFactorSafe

If set, and AccountingStorageEnforce includes Safe, jobs will only be able to run if the job can run to completion with the UsageFactor applied.

GraceTime

Preemption grace time, in seconds, to be extended to a job which has been selected for preemption.

GrpJobs

Maximum number of running jobs in aggregate for this QOS.

GrpJobsAccrue

Maximum number of pending jobs in aggregate able to accrue age priority for this QOS. This limit only applies to the job's QOS and not the partition's QOS.

GrpSubmit
GrpSubmitJobs

GrpTRESRunMins

Used to limit the combined total number of TRES minutes used by all jobs running with this QOS.  This takes into consideration time limit of running jobs and consumes it, if the limit is reached no new jobs are started until other jobs finish to allow time to free up.

GrpWall

Maximum wall clock time running jobs are able to be allocated in aggregate for this QOS. If this limit is reached submission requests will be denied and the running jobs will be killed.

ID

Name

Name of the QOS.

Preempt

Other QOS' this QOS can preempt.

NOTE: The Priority of a QOS is NOT related to QOS preemption, only Preempt is used to define which QOS can preempt others.

PreemptExemptTime

Specifies a minimum run time for jobs of this QOS before they are considered for preemption. This QOS option takes precedence over the global PreemptExemptTime. This is only honored for PreemptMode=REQUEUE and PreemptMode=CANCEL.
Setting to -1 disables the option, allowing another QOS or the global option to take effect. Setting to 0 indicates no minimum run time and supersedes the lower priority QOS (see OverPartQOS) and/or the global option in slurm.conf.

PreemptMode

Mechanism used to preempt jobs or enable gang scheduling for this QOS when the cluster PreemptType is set to preempt/qos. This QOS-specific PreemptMode will override the cluster-wide PreemptMode for this QOS. Unsetting the QOS specific PreemptMode, by specifying "OFF", "" or "Cluster", makes it use the default cluster-wide PreemptMode.
The GANG option is used to enable gang scheduling independent of whether preemption is enabled (i.e. independent of the PreemptType setting). It can be specified in addition to a PreemptMode setting with the two options comma separated (e.g. PreemptMode=SUSPEND,GANG).
See <https://slurm.schedmd.com/preempt.html> and <https://slurm.schedmd.com/gang_scheduling.html> for more details.

NOTE: For performance reasons, the backfill scheduler reserves whole nodes for jobs, not partial nodes. If during backfill scheduling a job preempts one or more other jobs, the whole nodes for those preempted jobs are reserved for the preemptor job, even if the preemptor job requested fewer resources than that. These reserved nodes aren't available to other jobs during that backfill cycle, even if the other jobs could fit on the nodes. Therefore, jobs may preempt more resources during a single backfill iteration than they requested.
NOTE: For heterogeneous job to be considered for preemption all components must be eligible for preemption. When a heterogeneous job is to be preempted the first identified component of the job with the highest order PreemptMode (SUSPEND (highest), REQUEUE, CANCEL (lowest)) will be used to set the PreemptMode for all components. The GraceTime and user warning signal for each component of the heterogeneous job remain unique. Heterogeneous jobs are excluded from GANG scheduling operations.

OFF

Is the default value and disables job preemption and gang scheduling. It is only compatible with PreemptType=preempt/none at a global level.

CANCEL

The preempted job will be cancelled.

GANG

Enables gang scheduling (time slicing) of jobs in the same partition, and allows the resuming of suspended jobs. Gang scheduling is performed independently for each partition, so if you only want time-slicing by OverSubscribe, without any preemption, then configuring partitions with overlapping nodes is not recommended. Time-slicing won't happen between jobs on different partitions.

NOTE: Heterogeneous jobs are excluded from GANG scheduling operations.

REQUEUE

Preempts jobs by requeuing them (if possible) or canceling them. For jobs to be requeued they must have the --requeue sbatch option set or the cluster wide JobRequeue parameter in slurm.conf must be set to 1.

SUSPEND

The preempted jobs will be suspended, and later the Gang scheduler will resume them. Therefore the SUSPEND preemption mode always needs the GANG option to be specified at the cluster level. Also, because the suspended jobs will still use memory on the allocated nodes, Slurm needs to be able to track memory resources to be able to suspend jobs.
If PreemptType=preempt/qos is configured and if the preempted job(s) and the preemptor job are on the same partition, then they will share resources with the Gang scheduler (time-slicing). If not (i.e. if the preemptees and preemptor are on different partitions) then the preempted jobs will remain suspended until the preemptor ends.

NOTE: Suspended jobs will not release GRES. Higher priority jobs will not be able to preempt to gain access to GRES.

WITHIN

Allows for preemption between jobs sharing the same qos. By default, fBPreemptType=preempt/qos will only consider jobs to be eligible for preemption if they do not share the same qos value.

Priority

What priority will be added to a job's priority when using this QOS.

NOTE: The Priority of a QOS is NOT related to QOS preemption, see Preempt instead.

RawUsage=<value>

This allows an administrator to reset the raw usage accrued to a QOS.  The only value currently supported is 0 (zero).  This is a settable specification only - it cannot be used as a filter to list accounts.

UsageFactor

Usage factor when running with this QOS. See below for more details.

UsageThreshold

A float representing the lowest fairshare of an association allowable to run a job.  If an association falls below this threshold and has pending jobs or submits new jobs those jobs will be held until the usage goes back above the threshold.  Use sshare to see current shares on the system.

WithDeleted

Display information with previously deleted data. A QOS that is deleted within 24 hours of being created and did not have a job run in the QOS during that time will be removed from the database. Otherwise, the QOS will be marked as deleted and will be viewable with the WithDeleted flag.

List/Show QoS Format Options

Description

An arbitrary string describing a QOS.

GraceTime

Preemption grace time to be extended to a job which has been selected for preemption in the format of hh:mm:ss.  The default value is zero, no preemption grace time is allowed on this QOS. This value is only meaningful for QOS PreemptMode=CANCEL and PreemptMode=REQUEUE.

GrpJobs

Maximum number of running jobs in aggregate for this QOS. To clear a previously set value use the modify command with a new value of -1.

GrpJobsAccrue

To clear a previously set value use the modify command with a new value of -1 for each TRES id. NOTE: This limit only applies when using the Priority Multifactor plugin.  The time is decayed using the value of PriorityDecayHalfLife or PriorityUsageResetPeriod as set in the slurm.conf.  When this limit is reached all associated jobs running will be killed and all future jobs submitted with this QOS will be delayed until they are able to run inside the limit.

GrpWall

Maximum wall clock time running jobs are able to be allocated in aggregate for this QOS. To clear a previously set value use the modify command with a new value of -1. NOTE: This limit only applies when using the Priority Multifactor plugin.  The time is decayed using the value of PriorityDecayHalfLife or PriorityUsageResetPeriod as set in the slurm.conf.  When this limit is reached all associated jobs running will be killed and all future jobs submitted with this QOS will be delayed until they are able to run inside the limit.

LimitFactor

A float that is factored into an associations [Grp|Max]TRES limits.  For example, if the LimitFactor is 2, then an association with a GrpTRES of 30 CPUs, would be allowed to allocate 60 CPUs when running under this QOS.

NOTE: This factor is only applied to associations running in this QOS and is not applied to any limits in the QOS itself.

To clear a previously set value use the modify command with a new value of -1.

Name

Name of the QOS.  Needed for creation.

Preempt

Other QOS' this QOS can preempt. Setting a Preempt to '' (two single quotes with nothing between them) restores its default setting.  You can also use the operator += and -= to add or remove certain QOS's from a QOS list.

PreemptMode

Mechanism used to preempt jobs of this QOS if the clusters PreemptType is configured to preempt/qos.  The default preemption mechanism is specified by the cluster-wide PreemptMode configuration parameter. Possible values are "Cluster" (meaning use cluster default), "Cancel", and "Requeue".  This option is not compatible with PreemptMode=OFF or PreemptMode=SUSPEND (i.e. preempted jobs must be removed from the resources).

Priority

UsageFactor

A float that is factored into a job’s TRES usage (e.g. RawUsage, TRESMins, TRESRunMins). For example, if the usagefactor was 2, for every TRESBillingUnit second a job ran it would count for 2. If the usagefactor was .5, every second would only count for half of the time. A setting of 0 would add no timed usage from the job.

The usage factor only applies to the job's QOS and not the partition QOS.

If the UsageFactorSafe flag is set and AccountingStorageEnforce includes Safe, jobs will only be able to run if the job can run to completion with the UsageFactor applied.

If the UsageFactorSafe flag is not set and AccountingStorageEnforce includes Safe, a job will be able to be scheduled without the UsageFactor applied and will be able to run without being killed due to limits.

If the UsageFactorSafe flag is not set and AccountingStorageEnforce does not include Safe, a job will be able to be scheduled without the UsageFactor applied and could be killed due to limits.

See AccountingStorageEnforce in slurm.conf man page.

Default is 1. To clear a previously set value use the modify command with a new value of -1.

Type

The type of the trackable resource. Current types are BB (Burst buffer), CPU, Energy, GRES, License, Memory, and Node.

TRES information

Trackable RESources (TRES) are used in many QOS or Association limits. When setting the limits they are comma separated list.  Each TRES has a different limit, i.e. GrpTRESMins=cpu=10,mem=20 would make 2 different limits 1 for 10 cpu minutes and 1 for 20 MB memory minutes. This is the case for each limit that deals with TRES.  To remove the limit -1 is used i.e. GrpTRESMins=cpu=-1 would remove only the cpu TRES limit.

NOTE: When dealing with Memory as a TRES all limits are in MB.

NOTE: The Billing TRES is calculated from a partition's TRESBillingWeights. It is temporarily calculated during scheduling for each partition to enforce billing TRES limits. The final Billing TRES is calculated after the job has been allocated resources. The final number can be seen in scontrol show jobs and sacct output.

Global Format Option

When using the format option for listing various fields you can put a %NUMBER afterwards to specify how many characters should be printed.

e.g. format=name%30 will print 30 characters of field name right justified.  A -30 will print 30 characters left justified.

Flat File Dump and Load

sacctmgr has the capability to load and dump Slurm association data to and from a file.  This method can easily add a new cluster or copy an existing cluster's associations into a new cluster with similar accounts. Each file contains Slurm association data for a single cluster. Be aware that QOS information is not currently included in the information that can be dumped to a file. QOS information can be retrieved and loaded using the REST API or it must be transferred to a new cluster manually. Comments can be put into the file with the # character. Each line of information must begin with one of the four titles; Cluster, Parent, Account or User. Following the title is a space, dash, space, entity value, then specifications. Specifications are colon separated. If any variable, such as an Organization name, has a space in it, surround the name with single or double quotes.

To create a file of associations you can run

sacctmgr dump tux file=tux.cfg

To load a previously created file you can run

sacctmgr load file=tux.cfg

sacctmgr dump/load must be run as a Slurm administrator or root. If using sacctmgr load on a database without any associations, it must be run as root (because there aren't any users in the database yet).

Other options for load are:

clean     - delete what was already there and start from scratch with this information.
Cluster=  - specify a different name for the cluster than that which is in the file.

Since the associations in the system follow a hierarchy, so does the file.  Anything that is a parent needs to be defined before any children.  The only exception is the understood 'root' account.  This is always a default for any cluster and does not need to be defined.

To edit/create a file start with a cluster line for the new cluster:

Cluster - cluster_name:MaxTRESPerJob=node=15

Anything included on this line will be the default for all associations on this cluster.  The options for the cluster are:

FairShare=

Number used in conjunction with other associations to determine job priority.

GrpJobs=

Maximum number of running jobs in aggregate for this association and all associations which are children of this association.

GrpJobsAccrue=

Maximum number of pending jobs in aggregate able to accrue age priority for this association and all associations which are children of this association.

GrpNodes=

Maximum number of nodes running jobs are able to be allocated in aggregate for this association and all associations which are children of this association.

GrpSubmitJobs=

Maximum number of jobs which can be in a pending or running state at any time in aggregate for this association and all associations which are children of this association.

GrpTRES=

Maximum number of TRES running jobs are able to be allocated in aggregate for this association and all associations which are children of this association.

GrpTRESMins=

The total number of TRES minutes that can possibly be used by past, present and future jobs running from this association and its children.

GrpTRESRunMins=

Used to limit the combined total number of TRES minutes used by all jobs running with this association and its children.  This takes into consideration time limit of running jobs and consumes it, if the limit is reached no new jobs are started until other jobs finish to allow time to free up.

GrpWall=

Maximum wall clock time running jobs are able to be allocated in aggregate for this association and all associations which are children of this association.

MaxJobs=

Maximum number of jobs the children of this association can run.

MaxTRESPerJob=

Maximum number of trackable resources per job the children of this association can run.

MaxWallDurationPerJob=

Maximum time (not related to job size) children of this accounts jobs can run.

QOS=

Comma separated list of Quality of Service names (Defined in sacctmgr).

After the entry for the root account you will have entries for the other accounts on the system. The entries will look similar to this example:

Parent - root
Account - cs:MaxTRESPerJob=node=5:MaxJobs=4:FairShare=399:MaxWallDurationPerJob=40:Description='Computer Science':Organization='LC'
Parent - cs
Account - test:MaxTRESPerJob=node=1:MaxJobs=1:FairShare=1:MaxWallDurationPerJob=1:Description='Test Account':Organization='Test'

Any of the options after a ':' can be left out and they can be in any order. If you want to add any sub accounts just list the Parent THAT HAS ALREADY BEEN CREATED before the account you are adding.

Account options are:

Description=

A brief description of the account.

FairShare=

Number used in conjunction with other associations to determine job priority.

GrpTRESMins=

Maximum number of TRES hours running jobs are able to be allocated in aggregate for this association and all associations which are children of this association. GrpTRESRunMins= Used to limit the combined total number of TRES minutes used by all jobs running with this association and its children.  This takes into consideration time limit of running jobs and consumes it, if the limit is reached no new jobs are started until other jobs finish to allow time to free up.

GrpTRES=

Maximum number of TRES running jobs are able to be allocated in aggregate for this association and all associations which are children of this association.

GrpJobs=

Maximum number of running jobs in aggregate for this association and all associations which are children of this association.

GrpJobsAccrue

Maximum number of pending jobs in aggregate able to accrue age priority for this association and all associations which are children of this association.

GrpNodes=

Maximum number of nodes running jobs are able to be allocated in aggregate for this association and all associations which are children of this association.

GrpSubmitJobs=

Maximum number of jobs which can be in a pending or running state at any time in aggregate for this association and all associations which are children of this association.

GrpWall=

Maximum wall clock time running jobs are able to be allocated in aggregate for this association and all associations which are children of this association.

MaxJobs=

Maximum number of jobs the children of this association can run.

MaxNodesPerJob=

Maximum number of nodes per job the children of this association can run.

MaxWallDurationPerJob=

Maximum time (not related to job size) children of this accounts jobs can run.

Organization=

Name of organization that owns this account.

QOS(=,+=,-=)

Comma separated list of Quality of Service names (Defined in sacctmgr).

To add users to an account add a line after the Parent line, similar to this:

Parent - test
User - adam:MaxTRESPerJob=node:2:MaxJobs=3:FairShare=1:MaxWallDurationPerJob=1:AdminLevel=Operator:Coordinator='test'

User options are:

AdminLevel=

Type of admin this user is (Administrator, Operator)
Must be defined on the first occurrence of the user.

Coordinator=

Comma separated list of accounts this user is coordinator over
Must be defined on the first occurrence of the user.

DefaultAccount=

System wide default account name
Must be defined on the first occurrence of the user.

FairShare=

Number used in conjunction with other associations to determine job priority.

MaxJobs=

Maximum number of jobs this user can run.

MaxTRESPerJob=

Maximum number of trackable resources per job this user can run.

MaxWallDurationPerJob=

Maximum time (not related to job size) this user can run.

QOS(=,+=,-=)

Comma separated list of Quality of Service names (Defined in sacctmgr).

Archive Functionality

Sacctmgr has the capability to archive to a flatfile and or load that data if needed later.  The archiving is usually done by the slurmdbd and it is highly recommended you only do it through sacctmgr if you completely understand what you are doing.  For slurmdbd options see "man slurmdbd" for more information. Loading data into the database can be done from these files to either view old data or regenerate rolled up data.

archive dump

Dump accounting data to file. Data will not be archived unless the corresponding purge option is included in this command or in slurmdbd.conf. This operation cannot be rolled back once executed. If one of the following options is not specified when sacctmgr is called, the value configured in slurmdbd.conf is used.

Directory=

Directory to store the archive data.

Events

Archive Events.  If not specified and PurgeEventAfter is set all event data removed will be lost permanently.

Jobs

Archive Jobs.  If not specified and PurgeJobAfter is set all job data removed will be lost permanently.

PurgeEventAfter=

Purge cluster event records older than time stated in months.  If you want to purge on a shorter time period you can include hours, or days behind the numeric value to get those more frequent purges. (e.g. a value of '12hours' would purge everything older than 12 hours.)

PurgeJobAfter=

Purge job records older than time stated in months.  If you want to purge on a shorter time period you can include hours, or days behind the numeric value to get those more frequent purges. (e.g. a value of '12hours' would purge everything older than 12 hours.)

PurgeStepAfter=

Purge step records older than time stated in months.  If you want to purge on a shorter time period you can include hours, or days behind the numeric value to get those more frequent purges. (e.g. a value of '12hours' would purge everything older than 12 hours.)

PurgeSuspendAfter=

Purge job suspend records older than time stated in months.  If you want to purge on a shorter time period you can include hours, or days behind the numeric value to get those more frequent purges. (e.g. a value of '12hours' would purge everything older than 12 hours.)

Script=

Run this script instead of the generic form of archive to flat files.

Steps

Archive Steps.  If not specified and PurgeStepAfter is set all step data removed will be lost permanently.

Suspend

Archive Suspend Data.  If not specified and PurgeSuspendAfter is set all suspend data removed will be lost permanently.

archive load

Load in to the database previously archived data. The archive file will not be loaded if the records already exist in the database - therefore, trying to load an archive file more than once will result in an error. When this data is again archived and purged from the database, if the old archive file is still in the directory ArchiveDir, a new archive file will be created (see ArchiveDir in the slurmdbd.conf man page), so the old file will not be overwritten and these files will have duplicate records.

Archive files from the current or any prior Slurm release may be loaded through archive load.

File=

File to load into database. The specified file must exist on the slurmdbd host, which is not necessarily the machine running the command.

Insert=

SQL to insert directly into the database.  This should be used very cautiously since this is writing your sql into the database.

Performance

Executing sacctmgr sends a remote procedure call to slurmdbd. If enough calls from sacctmgr or other Slurm client commands that send remote procedure calls to the slurmdbd daemon come in at once, it can result in a degradation of performance of the slurmdbd daemon, possibly resulting in a denial of service.

Do not run sacctmgr or other Slurm client commands that send remote procedure calls to slurmdbd from loops in shell scripts or other programs. Ensure that programs limit calls to sacctmgr to the minimum necessary for the information you are trying to gather.

Environment Variables

Some sacctmgr options may be set via environment variables. These environment variables, along with their corresponding options, are listed below. (Note: Command line options will always override these settings.)

SLURM_CONF

The location of the Slurm configuration file.

SLURM_DEBUG_FLAGS

Specify debug flags for sacctmgr to use. See DebugFlags in the slurm.conf(5) man page for a full list of flags. The environment variable takes precedence over the setting in the slurm.conf.

Examples

NOTE: There is an order to set up accounting associations. You must define clusters before you add accounts and you must add accounts before you can add users.

$ sacctmgr create cluster tux
$ sacctmgr create account name=science fairshare=50
$ sacctmgr create account name=chemistry parent=science fairshare=30
$ sacctmgr create account name=physics parent=science fairshare=20
$ sacctmgr create user name=adam cluster=tux account=physics fairshare=10
$ sacctmgr delete user name=adam cluster=tux account=physics
$ sacctmgr delete account name=physics cluster=tux
$ sacctmgr modify user where name=adam cluster=tux account=physics set maxjobs=2 maxwall=30:00
$ sacctmgr add user brian account=chemistry
$ sacctmgr list associations cluster=tux format=Account,Cluster,User,Fairshare tree withd
$ sacctmgr list transactions Action="Add Users" Start=11/03-10:30:00 format=Where,Time
$ sacctmgr dump cluster=tux file=tux_data_file
$ sacctmgr load tux_data_file

A user's account can not be changed directly. A new association needs to be created for the user with the new account. Then the association with the old account can be deleted.

When modifying an object placing the key words 'set' and the optional 'where' is critical to perform correctly below are examples to produce correct results.  As a rule of thumb anything you put in front of the set will be used as a quantifier.  If you want to put a quantifier after the key word 'set' you should use the key word 'where'. The following is wrong:

$ sacctmgr modify user name=adam set fairshare=10 cluster=tux

This will produce an error as the above line reads modify user adam set fairshare=10 and cluster=tux. Either of the following is correct:

$ sacctmgr modify user name=adam cluster=tux set fairshare=10
$ sacctmgr modify user name=adam set fairshare=10 where cluster=tux

When changing qos for something only use the '=' operator when wanting to explicitly set the qos to something.  In most cases you will want to use the '+=' or '-=' operator to either add to or remove from the existing qos already in place.

If a user already has qos of normal,standby for a parent or it was explicitly set you should use qos+=expedite to add this to the list in this fashion.

If you are looking to only add the qos expedite to only a certain account and or cluster you can do that by specifying them in the sacctmgr line.

$ sacctmgr modify user name=adam set qos+=expedite

or

$ sacctmgr modify user name=adam acct=this cluster=tux set qos+=expedite

Let's give an example how to add QOS to user accounts. List all available QOSs in the cluster.

$ sacctmgr show qos format=name
      Name
  ---------
    normal
  expedite

List all the associations in the cluster.

$ sacctmgr show assoc format=cluster,account,qos
   Cluster    Account    QOS
  --------  ---------- -----
  zebra       root         normal
  zebra       root         normal
  zebra          g         normal
  zebra         g1         normal

Add the QOS expedite to account G1 and display the result. Using the operator += the QOS will be added together with the  existing QOS to this account.

$ sacctmgr modify account name=g1 set qos+=expedite
$ sacctmgr show assoc format=cluster,account,qos
   Cluster    Account   QOS
   --------  --------  -------
   zebra       root         normal
   zebra       root         normal
   zebra          g         normal
   zebra         g1  expedite,normal

Now set the QOS expedite as the only QOS for the account G and display the result. Using the operator = that expedite is the only usable QOS by account G

$ sacctmgr modify account name=G set qos=expedite
$ sacctmgr show assoc format=cluster,account,user,qos
   Cluster    Account  QOS
  ---------   -------- -----
  zebra       root      normal
  zebra       root      normal
  zebra          g      expedite
  zebra         g1      expedite,normal

If a new account is added under the account G it will inherit the QOS expedite and it will not have access to QOS normal.

$ sacctmgr add account banana parent=G
$ sacctmgr show assoc format=cluster,account,qos
   Cluster    Account   QOS
  ---------  --------  -----
  zebra       root       normal
  zebra       root       normal
  zebra          g       expedite
  zebra     banana       expedite
  zebra         g1       expedite,normal

An example of listing trackable resources:

$ sacctmgr show tres
      Type              Name      ID
---------- ----------------- --------
       cpu                          1
       mem                          2
    energy                          3
      node                          4
   billing                          5
      gres         gpu:tesla     1001
   license               vcs     1002
        bb              cray     1003
