    SINFO Execute Line

    SINFO reports current status information on node partitions and on individual nodes for computer systems managed by SLURM. SINFO's reports can help you plan job submittals and avoid hardware problems. SINFO's output is a table whose content and format you can control with SINFO options. (To report on job status rather than on node status, use SQUEUE instead.)

    BASIC RUN.
    To run SINFO (on any machine with SLURM installed), type

    sinfo [opts]


    where opts is a blank-delimited list of SINFO output-control options and their quoted, comma-delimited arguments.

    COLUMNS.
    If run without options, SINFO reports by default on these node properties (in this order in six columns left to right) and then ends:

         partition
         availability
         time limit
         node count
         node state [for state codes, see later section]
         node list (specific node names covered)
    
    
    See the first example below for typical default SINFO output. You can change the properties reported (and the order of the output columns) by using SINFO's -o (lowercase oh, --format) option.

    ROWS.
    Each row in the SINFO report describes one node partition (or, if you use node-oriented options such as -n or -N, one or more specific nodes). SINFO sorts the rows by partition name (in a preconfigured order as specified in the file /etc/slurm/slurm.conf) and then in decreasing order by node state (or in increasing order by node name for node-oriented reports). However, you can change the order in which SINFO sorts rows by using SINFO's -S (uppercase ess, --sort) option, described in the next section.
