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=<account>
              Display information for specific accounts (comma separated list).

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

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

       -o, --format=<output_format>
              Comma separated list of fields (use "--helpformat" for a list of available fields).

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

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

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

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

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

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

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

              not displayed.

              Display the version number of sshare.

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  (the  default,  unless   NO_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.

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

PERFORMANCE

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

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

ENVIRONMENT VARIABLES

       Some sshare 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  sshare  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

       Display information about users in a particular account:

              $ sshare -A <Account>

       Display information about a specific user in a parsable format:

              $ sshare --parsable --users=<User>
