sinfo(1)
NAME
sinfo - view information about Slurm nodes and partitions.
SYNOPSIS
sinfo [OPTIONS...]
DESCRIPTION
sinfo is used to view partition and node information for a system running Slurm.
OPTIONS
-a, --all
Display information about all partitions. This causes
information to be displayed about partitions that are configured
as hidden and partitions that are unavailable to user's group.
-b, --bgl
Display information about bglblocks (on Blue Gene systems only).
-d, --dead
If set only report state information for non-responding (dead)
nodes.
-e, --exact
If set, do not group node information on multiple nodes unless
their configurations to be reported are identical. Otherwise cpu
count, memory size, and disk space for nodes will be listed with
the minimum value followed by a "+" for nodes with the same
partition and state (e.g., "250+").
-h, --noheader
Do not print a header on the output.
--help Print a message describing all sinfo options.
--hide Do not display information about hidden partitions. By default,
partitions that are configured as hidden or are not available to
the user's group will not be displayed (i.e. this is the default
behavior).
-i <seconds>, --iterate=<seconds>
Print the state on a periodic basis. Sleep for the indicated
number of seconds between reports. By default, prints a time
stamp with the header.
-l, --long
Print more detailed information. This is ignored if the
--format option is specified.
-M, --clusters=<string>
Clusters to issue commands to. Multiple cluster names may be
comma separated. A value of of 'all' will query to run on all
clusters.
-n <nodes>, --nodes=<nodes>
Print information only about the specified node(s). Multiple
nodes may be comma separated or expressed using a node range
expression. For example "linux[00-07]" would indicate eight
nodes, "linux00" through "linux07." Performance of the command
can be measurably improved for systems with large numbers of
nodes when a single node name is specified.
--noconvert
Don't convert units from their original type (e.g. 2048M won't
be converted to 2G).
-N, --Node
Print information in a node-oriented format with one line per
node. The default is to print information in a
partition-oriented format. This is ignored if the --format
option is specified.
-o <output_format>, --format=<output_format>
Specify the information to be displayed using an sinfo format
string. Format strings transparently used by sinfo when running
with various options are
default "%#P %.5a %.10l %.6D %.6t %N"
--summarize "%#P %.5a %.10l %.16F %N"
--long "%#P %.5a %.10l %.10s %.4r %.8h %.10g %.6D %.11T
%N"
--Node "%#N %.6D %#P %6t"
--long --Node "%#N %.6D %#P %.11T %.4c %.8z %.6m %.8d %.6w %.8f
%20E"
--list-reasons "%20E %9u %19H %N"
--long --list-reasons
"%20E %12U %19H %6t %N"
In the above format strings, the use of "#" represents the
maximum length of any partition name or node list to be printed.
A pass is made over the records to be printed to establish the
size in order to align the sinfo output, then a second pass is
made over the records to print them. Note that the literal
character "#" itself is not a valid field length specification,
but is only used to document this behaviour.
The field specifications available include:
%all Print all fields available for this data type with a
vertical bar separating each field.

-p <partition>, --partition=<partition>
Print information only about the specified partition(s).
Multiple partitions are separated by commas.
-r, --responding
If set only report state information for responding nodes.
-R, --list-reasons
List reasons nodes are in the down, drained, fail or failing
state. When nodes are in these states Slurm supports optional
inclusion of a "reason" string by an administrator. This option
will display the first 35 characters of the reason field and
list of nodes with that reason for all nodes that are, by
default, down, drained, draining or failing. This option may be
used with other node filtering options (e.g. -r, -d, -t, -n),
however, combinations of these options that result in a list of
nodes that are not down or drained or failing will not produce
any output. When used with -l the output additionally includes
the current node state.
-s, --summarize
List only a partition state summary with no node state details.
This is ignored if the --format option is specified.
-S <sort_list>, --sort=<sort_list>
Specification of the order in which records should be reported.
This uses the same field specification as the <output_format>.
Multiple sorts may be performed by listing multiple sort fields
separated by commas. The field specifications may be preceded
by "+" or "-" for ascending (default) and descending order
respectively. The partition field specification, "P", may be
preceded by a "#" to report partitions in the same order that
they appear in Slurm's configuration file, slurm.conf. For
example, a sort value of "+P,-m" requests that records be
printed in order of increasing partition name and within a
partition by decreasing memory size. The default value of sort
is "#P,-t" (partitions ordered as configured then decreasing
node state). If the --Node option is selected, the default sort
value is "N" (increasing node name).
-t <states> , --states=<states>
List nodes only having the given state(s). Multiple states may
be comma separated and the comparison is case insensitive.
Possible values include (case insensitive): ALLOC, ALLOCATED,
COMP, COMPLETING, DOWN, DRAIN (for node in DRAINING or DRAINED
states), DRAINED, DRAINING, ERR, ERROR, FAIL, FUTURE, FUTR,
IDLE, MAINT, MIX, MIXED, NO_RESPOND, NPC, PERFCTRS, POWER_DOWN,
POWER_UP, RESV, RESERVED, UNK, and UNKNOWN. By default nodes in
the specified state are reported whether they are responding or
not. The --dead and --responding options may be used to
filtering nodes by the responding flag.
-T, --reservation
Only display information about Slurm reservations.
--usage
Print a brief message listing the sinfo options.
-v, --verbose
Provide detailed event logging through program execution.
-V, --version
Print version information and exit.
OUTPUT FIELD DESCRIPTIONS
AVAIL Partition state: up or down.
CPUS Count of CPUs (processors) on each node.

THREADS
Count of threads on these nodes.
GROUPS Resource allocations in this partition are restricted to the
named groups. all indicates that all groups may use this
partition.
JOB_SIZE
Minimum and maximum node count that can be allocated to any user
job. A single number indicates the minimum and maximum node
count are the same. infinite is used to identify partitions
without a maximum node count.
TIMELIMIT
Maximum time limit for any user job in
days-hours:minutes:seconds. infinite is used to identify
partitions without a job time limit.
MEMORY Size of real memory in megabytes on these nodes.
NODELIST or BP_LIST (BlueGene systems only)
Names of nodes associated with this configuration/partition.
NODES Count of nodes with this particular configuration.
NODES(A/I)
Count of nodes with this particular configuration by node state
in the form "available/idle".
NODES(A/I/O/T)
Count of nodes with this particular configuration by node state
in the form "available/idle/other/total".
PARTITION
Name of a partition. Note that the suffix "*" identifies the
default partition.
ROOT Is the ability to allocate resources in this partition
restricted to user root, yes or no.
OVERSUBSCRIBE
Will jobs allocated resources in this partition oversubscribe
those compute resources (i.e. CPUs). no indicates resources are
never oversubscribed. exclusive indicates whole nodes are
dedicated to jobs (equivalent to srun --exclusive option, may be
used even with select/cons_res managing individual processors).
force indicates resources are always available to be
oversubscribed. yes indicates resource may be oversubscribed or
not per job's resource allocation.
STATE State of the nodes. Possible states include: allocated,
completing, down, drained, draining, fail, failing, future,
idle, maint, mixed, perfctrs, power_down, power_up, reserved,
and unknown plus Their abbreviated forms: alloc, comp, down,
drain, drng, fail, failg, futr, idle, maint, mix, npc, pow_dn,
pow_up, resv, and unk respectively. Note that the suffix "*"
identifies nodes that are presently not responding.
TMP_DISK
Size of temporary disk space in megabytes on these nodes.
NODE STATE CODES
Node state codes are shortened as required for the field size. These
node states may be followed by a special character to identify state
flags associated with the node. The following node sufficies and
states are used:
* The node is presently not responding and will not be allocated any
new work. If the node remains non-responsive, it will be placed in
the DOWN state (except in the case of COMPLETING, DRAINED,
DRAINING, FAIL, FAILING nodes).
~ The node is presently in a power saving mode (typically running at
reduced frequency).
# The node is presently being powered up or configured.
$ The node is currently in a reservation with a flag value of
"maintenance" or is scheduled to be rebooted.
ALLOCATED The node has been allocated to one or more jobs.
ALLOCATED+ The node is allocated to one or more active jobs plus one
or more jobs are in the process of COMPLETING.
COMPLETING All jobs associated with this node are in the process of
COMPLETING. This node state will be removed when all of
the job's processes have terminated and the Slurm epilog
program (if any) has terminated. See the Epilog parameter
description in the slurm.conf man page for more
information.
DOWN The node is unavailable for use. Slurm can automatically
place nodes in this state if some failure occurs. System
administrators may also explicitly place nodes in this
state. If a node resumes normal operation, Slurm can
automatically return it to service. See the ReturnToService
and SlurmdTimeout parameter descriptions in the
slurm.conf(5) man page for more information.
DRAINED The node is unavailable for use per system administrator
request. See the update node command in the scontrol(1)
man page or the slurm.conf(5) man page for more
information.
DRAINING The node is currently executing a job, but will not be
allocated to additional jobs. The node state will be
changed to state DRAINED when the last job on it completes.
Nodes enter this state per system administrator request.
See the update node command in the scontrol(1) man page or
the slurm.conf(5) man page for more information.
ERROR The node is currently in an error state and not capable of
running any jobs. Slurm can automatically place nodes in
this state if some failure occurs. System administrators
may also explicitly place nodes in this state. If a node
resumes normal operation, Slurm can automatically return it
to service. See the ReturnToService and SlurmdTimeout
parameter descriptions in the slurm.conf(5) man page for
more information.
FAIL The node is expected to fail soon and is unavailable for
use per system administrator request. See the update node
command in the scontrol(1) man page or the slurm.conf(5)
man page for more information.
FAILING The node is currently executing a job, but is expected to
fail soon and is unavailable for use per system
administrator request. See the update node command in the
scontrol(1) man page or the slurm.conf(5) man page for more
information.
FUTURE The node is currently not fully configured, but expected to
be available at some point in the indefinite future for
use.
IDLE The node is not allocated to any jobs and is available for
use.
MAINT The node is currently in a reservation with a flag value of
"maintenance" or is scheduled to be rebooted.
MIXED The node has some of its CPUs ALLOCATED while others are
IDLE.
PERFCTRS (NPC)
Network Performance Counters associated with this node are
in use, rendering this node as not usable for any other
jobs
POWER_DOWN The node is currently powered down and not capable of
running any jobs.
POWER_UP The node is currently in the process of being powered up.
RESERVED The node is in an advanced reservation and not generally
available.
UNKNOWN The Slurm controller has just started and the node's state
has not yet been determined.
ENVIRONMENT VARIABLES
Some sinfo 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.)
SINFO_ALL -a, --all
SINFO_FORMAT -o <output_format>, --format=<output_format>
SINFO_PARTITION -p <partition>, --partition=<partition>
SINFO_SORT -S <sort>, --sort=<sort>
SLURM_CLUSTERS Same as --clusters
SLURM_CONF The location of the Slurm configuration file.
SLURM_TIME_FORMAT Specify the format used to report time stamps. A
value of standard, the default value, generates
output in the form
"year-month-dateThour:minute:second". A value of
relative returns only "hour:minute:second" if the
current day. For other dates in the current year
it prints the "hour:minute" preceded by "Tomorr"
(tomorrow), "Ystday" (yesterday), the name of the
day for the coming week (e.g. "Mon", "Tue", etc.),
otherwise the date (e.g. "25 Apr"). For other
years it returns a date month and year without a
time (e.g. "6 Jun 2012"). All of the time stamps
use a 24 hour format.
A valid strftime() format can also be specified.
For example, a value of "%a %T" will report the day
of the week and a time stamp (e.g. "Mon 12:34:56").
