SLURM Reference Manual for HP XC System Software

SINFO (List Nodes)
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 (page 46) 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 (page 61) 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.
