NAME

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

CONTENTS

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 GrpCPUMins limit, Partitions and accumulated currently running CPU-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.

-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 cpu-seconds of all the jobs that charged the account by the 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 cpu-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.

GrpCPUMins
  The CPU-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.

CPURunMins
  The number of CPU-minutes allocated by jobs currently running against the account. Used to limit the combined total number of CPU 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.

More information about Fair Tree can be found in doc/html/fair_tree.html or

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)
SLURM_CONF The location of the Slurm configuration file.

EXAMPLES

> sshare -A <Account>
> sshare --parsable --users=<User>
