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.
- -A, --accounts=
Display information for specific accounts (comma separated list).
- -a, --all
Display information for all users.
- -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
If there are association based partitions in the system print their names.
- -n, --noheader
No header will be added to the beginning of the output.
- -o, --format=
Comma separated list of fields (use "--helpformat" for a list of available fields).
- -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.
--usage Display a description of sshare options and commands.
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
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.
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)
The location of the Slurm configuration file.
- 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>
