sinfo

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 partions. 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.

-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."

-N, --Node

Print information in a node-oriented format. 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

"%9P %5a %.10l %.5D %6t %N"

--summarize

"%9P %5a %.10l %16F %N"

--long

"%9P %5a %.10l %.8s %4r %5h %10g %.5D %11T %N"

--Node

"%N %.5D %9P %6t"

--long --Node

"%N %.5D %9P %11T %.4c %.8z %.6m %.8d %.6w %8f %R"

--list-reasons

"%50R %N"

--long --list-reasons

"%50R %6t %N"

In the above format strings the use of "#" represents the maximum length of an node list to be printed.

The field specifications available include:

%a

State/availability of a partition

%A

Number of nodes by state in the format "allocated/idle". Do not use this with a node state option ("%t" or "%T") or the different node states will be placed on separate lines.

%c

Number of CPUs per node

%C

Number of CPUs by state in the format "allocated/idle/other/total". Do not use this with a node state option ("%t" or "%T") or the different node states will be placed on separate lines.

%d

Size of temporary disk space per node in megabytes

%D

Number of nodes

%E

The reason a node is unavailable (down, drained, or draining states). This is the same as %R except the entries will be sorted by time rather than the reason string.

%f

Features associated with the nodes

%F

Number of nodes by state in the format "allocated/idle/other/total". Do not use this with a node state option ("%t" or "%T") or the different node states will be placed on separate lines.

%g

Groups which may use the nodes

%h

Jobs may share nodes, "yes", "no", or "force"

%l

Maximum time for any job in the format "days-hours:minutes:seconds"

%L

Default time for any job in the format "days-hours:minutes:seconds"

%m

Size of memory per node in megabytes

%N

List of node names

%P

Partition name

%r

Only user root may initiate jobs, "yes" or "no"

%R

The reason a node is unavailable (down, drained, draining, fail or failing states)

%s

Maximum job size in nodes

%S

Allowed allocating nodes

%t

State of nodes, compact form

%T

State of nodes, extended form

%w

Scheduling weight of the nodes

%X

Number of sockets per node

%Y

Number of cores per socket

%Z

Number of threads per core

%z

Extended processor information: number of sockets, cores, threads (S:C:T) per node

%.<*>

right justification of the field

%<Number><*>

size of field

-p <partition>, --partition=<partition>

Print information only about the specified partition.

-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 specifciation 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 assending (default) and desending 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, FAIL, FAILING, IDLE, MAINT, NO_RESPOND, POWER_SAVE, 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.

--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.

S:C:T

Count of sockets (S), cores (C), and threads (T) on these nodes.

SOCKETS

Count of sockets on these nodes.

CORES

Count of cores on these nodes.

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.

SHARE

Will jobs allocated resources in this partition share those resources. no indicates resources are never shared. exclusive indicates whole nodes are dedicated to jobs (equivalent to srun --exclusive option, may be used even with shared/cons_res managing individual processors). force indicates resources are always available to be shared. yes indicates resource may be shared or not per job's resource allocation.

STATE

State of the nodes. Possible states include: allocated, completing, down, drained, draining, fail, failing, idle, and unknown plus their abbreviated forms: alloc, comp, donw, drain, drng, fail, failg, idle, 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. If the node state code is followed by "*", this indicates 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).

If the node state code is followed by "~", this indicates the node is presently in a power saving mode (typically running at reduced frequency). If the node state code is followed by "#", this indicates the node is presently being powered up or configured.

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.

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.

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 "maintainence".

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
