    .SH "DESCRIPTION"
    \fBsshare\fR is used to view Slurm share information. This command is
    only viable when running with the priority/multifactor plugin.
    The sshare information is derived from a database with the interface
    being provided by \fBslurmdbd\fR (Slurm Database daemon) which is
    read in from the slurmctld and used to process the shares available
    to a given association. sshare provides Slurm share information of
    Account, User, Raw Shares, Normalized Shares, Raw Usage, Normalized
    Usage, Effective Usage, the Fair\-share factor, the GrpTRESMins limit,
    Partitions and accumulated currently running TRES\-minutes for each association.

    .SH "SSHARE OUTPUT FIELDS"

    .TP
    \f3Account\fP
    The Account.
    .IP

    .TP
    \f3User\fP
    The User.
    .IP
    The number of tres\-seconds (cpu\-seconds if TRESBillingWeights is not defined)
    of all the jobs charged to the account or user. This number will decay over
    time when PriorityDecayHalfLife is defined.
    .IP

    .TP
    \f3Norm Usage\fP (only appears with \fBsshare \-l\fR option)
    The Raw Usage normalized to the total number of tres\-seconds of all
    jobs run on the cluster, subject to the PriorityDecayHalfLife decay
    when defined.
    .IP

    .TP
    \f3Effectv Usage\fP
    The Effective Usage augments the normalized usage to account for usage
    from sibling accounts.
    .IP

    .TP
    \f3FairShare\fP
    The Fair\-Share factor, based on a user or account's assigned shares and
    the effective usage charged to them or their accounts.
    .IP

    .TP
    \f3GrpTRESMins\fP
    The TRES\-minutes limit set on the account. The total number of cpu
    minutes that can possibly be used by past, present and future jobs
    running from this account and its children.
    .IP

    .TP
    \f3GrpTRESRaw\fP
    The raw TRES usage that has been used by jobs running from
    this account and its children.
    .IP

    .TP
    \f3TRESRunMins\fP
    The number of TRES\-minutes allocated by jobs currently running against
    the account. Used to limit the combined total number of TRES minutes
    used by all jobs running with this account 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.
    .IP

    .SH "FAIR_TREE MODIFICATIONS"
    When PriorityFlags=FAIR_TREE is set (the default, unless NO_FAIR_TREE is set),
    calculations are done differently.
    As a result, the following fields are added or modified:

    as Norm Shares / Effectv Usage. If an association is over\-served, the value is
    between 0 and 1. If an association is under\-served, the value is greater than 1.
    Associations with no usage receive the highest possible value, infinity.
    .IP

    .LP
    More information about Fair Tree can be found in doc/html/fair_tree.html or
    at https://slurm.schedmd.com/fair_tree.html

    .SH "PERFORMANCE"
    .PP
    Executing \fBsshare\fR sends a remote procedure call to \fBslurmctld\fR. If
    enough calls from \fBsshare\fR or other Slurm client commands that send remote
    procedure calls to the \fBslurmctld\fR daemon come in at once, it can result in
    a degradation of performance of the \fBslurmctld\fR daemon, possibly resulting
    in a denial of service.
    .PP
    Do not run \fBsshare\fR or other Slurm client commands that send remote
    procedure calls to \fBslurmctld\fR from loops in shell scripts or other
    programs. Ensure that programs limit calls to \fBsshare\fR to the minimum
    necessary for the information you are trying to gather.

    .SH "ENVIRONMENT VARIABLES"
    .PP
    Some \fBsshare\fR 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.)

    .IP

    .TP
    \fBSLURM_DEBUG_FLAGS\fR

    \fBslurm.conf\fR(5) man page for a full list of flags. The environment
    variable takes precedence over the setting in the slurm.conf.
