sshare(1)

NAME
sshare - Tool for listing the shares of associations to a cluster.

SYNOPSIS
sshare [OPTIONS...]

DESCRIPTION
sshare 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 slurmdbd (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.

OPTIONS

-A, --accounts=
    Display information for specific accounts (comma separated list).

-a, --all
    Display information for all users.

-h, --noheader
    No header will be added to the beginning of the output.

-l, --long
    Long listing - includes the normalized usage information.

-M, --clusters=<string>
    Clusters to issue commands to. Note that the SlurmDBD must be up for this option to work properly.

-m, --partition
    Is there are association based partition in the system print their names.

-p, --parsable
    Output will be '|' delimited with a '|' at the end.

-P, --parsable2
    Output will be '|' delimited without a '|' at the end.

-u, --users=
    Display information for specific users (comma separated list).

-U, --Users
    If specified only the users information are printed, the parent and ancestors are not displayed.

-v, --verbose
    Display more information about the specified options.

-V, --version
    Display the version number of sshare.

--help
    --usage Display a description of sshare options and commands.

SSHARE OUTPUT FIELDS

Account
    The Account.

User
    The User.

Raw Shares
    The raw shares assigned to the user or account.

Norm Shares
    The shares assigned to the user or account normalized to the total number of assigned shares.

Raw Usage
    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.

Norm Usage (only appears with sshare -l 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.

Effectv Usage
    The Effective Usage augments the normalized usage to account for usage from sibling accounts.

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

GrpTRESMins
    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.

GrpTRESRaw
    The raw TRES usage that has been used by jobs running from this account and its children.

TRESRunMins
    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.

FAIR_TREE MODIFICATIONS
When PriorityFlags=FAIR_TREE is set, calculations are done differently. As a result, the following fields are added or modified:

Norm Shares
    The shares assigned to the user or account normalized to the total number of assigned shares within the level.

Effectv Usage
    Effectv Usage is the association's usage normalized with its parent.

Level FS (only appears with sshare -l option)
    This is the association's fairshare value compared to its siblings, calculated 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.

ENVIRONMENT VARIABLES

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