 .TH SINFO "1" "May 2008" "sinfo 2.0" "Slurm components"

 .SH "NAME"
 sinfo \- view information about SLURM nodes and partitions.

 .SH "SYNOPSIS"
 \fBsinfo\fR [\fIOPTIONS\fR...]
 .SH "DESCRIPTION"
 \fBsinfo\fR is used to view partition and node information for a
 system running SLURM.

 .SH "OPTIONS"

 .TP
 \fB\-a\fR, \fB\-\-all\fR
 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.

 .TP
 \fB\-b\fR, \fB\-\-bgl\fR
 Display information about bglblocks (on Blue Gene systems only).

 .TP
 \fB\-d\fR, \fB\-\-dead\fR
 If set only report state information for non\-responding (dead) nodes.

 .TP
 \fB\-e\fR, \fB\-\-exact\fR
 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+").

 .TP
 \fB\-h\fR, \fB\-\-noheader\fR
 Do not print a header on the output.

 .TP
 \fB\-\-help\fR
 Print a message describing all \fBsinfo\fR options.
 .TP

 \fB\-\-hide\fR
 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).

 .TP
 \fB\-i <seconds>\fR, \fB\-\-iterate=<seconds>\fR
 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.

 .TP
 \fB\-l\fR, \fB\-\-long\fR
 Print more detailed information.
 This is ignored if the \fB\-\-format\fR option is specified.

 .TP
 \fB\-n <nodes>\fR, \fB\-\-nodes=<nodes>\fR
 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."

 .TP
 \fB\-N\fR, \fB\-\-Node\fR
 Print information in a node\-oriented format.
 The default is to print information in a partition\-oriented format.
 This is ignored if the \fB\-\-format\fR option is specified.

 .TP
 \fB\-o <output_format>\fR, \fB\-\-format=<output_format>\fR
 Specify the information to be displayed using an \fBsinfo\fR
 format string. Format strings transparently used by \fBsinfo\fR
 when running with various options are

 .TP 4
 \fB%a\fR
 State/availability of a partition
 .TP
 \fB%A\fR

 Do not use this with a node state option ("%t" or "%T") or
 the different node states will be placed on separate lines.
 .TP
 \fB%c\fR

 .RE

 .TP
 \fB\-p <partition>\fR, \fB\-\-partition=<partition>\fR
 Print information only about the specified partition.

 .TP
 \fB\-r\fR, \fB\-\-responding\fR
 If set only report state information for responding nodes.

 .TP
 \fB\-R\fR, \fB\-\-list\-reasons\fR
 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. \fB\-r\fR, \fB\-d\fR, \fB\-t\fR, \fB\-n\fR),
 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 \fB\-l\fR the output additionally includes
 the current node state.

 .TP
 \fB\-s\fR, \fB\-\-summarize\fR
 List only a partition state summary with no node state details.
 This is ignored if the \fB\-\-format\fR option is specified.

 .TP
 \fB\-S <sort_list>\fR, \fB\-\-sort=<sort_list>\fR
 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 preceeded
 by "+" or "\-" for assending (default) and desending order
 respectively.  The partition field specification, "P", may be
 preceeded by a "#" to report partitions in the same order that
 they appear in SLURM's  configuration file, \fBslurm.conf\fR.
 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 \fB\-\-Node\fB option is selected, the
 default sort value is "N" (increasing node name).

 .TP
 \fB\-t <states>\fR , \fB\-\-states=<states>\fR
 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 \fB\-\-dead\fR and \fB\-\-responding\fR options may be
 used to filtering nodes by the responding flag.

 .TP
 \fB\-\-usage\fR
 Print a brief message listing the \fBsinfo\fR options.

 .TP
 \fB\-v\fR, \fB\-\-verbose\fR
 Provide detailed event logging through program execution.

 .TP
 \fB\-V\fR, \fB\-\-version\fR
 Print version information and exit.

 .SH "OUTPUT FIELD DESCRIPTIONS"
 .TP

 named groups.  \fBall\fR indicates that all groups may use
 this partition.
 .TP
 \fBJOB_SIZE\fR
 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.  \fBinfinite\fR is used to identify
 partitions without a maximum node count.
 .TP
 \fBTIMELIMIT\fR
 Maximum time limit for any user job in
 days\-hours:minutes:seconds.  \fBinfinite\fR is used to identify
 partitions without a job time limit.
 .TP
 \fBMEMORY\fR
 Size of real memory in megabytes on these nodes.
 .TP
 \fBNODELIST\fR or \fBBP_LIST\fR (BlueGene systems only)
 Names of nodes associated with this configuration/partition.
 .TP
 \fBNODES\fR
 Count of nodes with this particular configuration.
 .TP
 \fBNODES(A/I)\fR
 Count of nodes with this particular configuration by node
 state in the form "available/idle".
 .TP
 \fBNODES(A/I/O/T)\fR
 Count of nodes with this particular configuration by node
 state in the form "available/idle/other/total".
 .TP
 \fBPARTITION\fR
 Name of a partition.  Note that the suffix "*" identifies the
 default partition.
 .TP
 \fBROOT\fR
 Is the ability to allocate resources in this partition
 restricted to user root, \fByes\fR or \fBno\fR.
 .TP
 \fBSHARE\fR
 Will jobs allocated resources in this partition share those
 resources.
 \fBno\fR indicates resources are never shared.
 \fBexclusive\fR indicates whole nodes are dedicated to jobs
 (equivalent to srun \-\-exclusive option, may be used even
 with shared/cons_res managing individual processors).
 \fBforce\fR indicates resources are always available to be shared.
 \fByes\fR indicates resource may be shared or not
 per job's resource allocation.
 .TP
 \fBSTATE\fR
 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.
 .TP
 \fBTMP_DISK\fR
 Size of temporary disk space in megabytes on these nodes.

 .SH "NODE STATE CODES"
 .PP
 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 \fBDOWN\fR state (except in the case of
 \fBCOMPLETING\fR, \fBDRAINED\fR, \fBDRAINING\fR,
 \fBFAIL\fR, \fBFAILING\fR 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).
 .TP 12
 \fBALLOCATED\fR
 The node has been allocated to one or more jobs.
 .TP
 \fBALLOCATED+\fR
 The node is allocated to one or more active jobs plus
 one or more jobs are in the process of COMPLETING.
 .TP
 \fBCOMPLETING\fR
 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 \fBEpilog\fR
 parameter description in the \fBslurm.conf\fR man page for
 more information.
 .TP
 \fBDOWN\fR
 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 \fBReturnToService\fR
 and \fBSlurmdTimeout\fR parameter descriptions in the
 \fBslurm.conf\fR(5) man page for more information.
 .TP
 \fBDRAINED\fR
 The node is unavailable for use per system administrator
 request.  See the \fBupdate node\fR command in the
 \fBscontrol\fR(1) man page or the \fBslurm.conf\fR(5) man page
 for more information.
 .TP
 \fBDRAINING\fR
 The node is currently executing a job, but will not be allocated
 to additional jobs. The node state will be changed to state
 \fBDRAINED\fR when the last job on it completes. Nodes enter
 this state per system administrator request. See the \fBupdate
 node\fR command in the \fBscontrol\fR(1) man page or the
 \fBslurm.conf\fR(5) man page for more information.
 .TP
 \fBFAIL\fR
 The node is expected to fail soon and is unavailable for
 use per system administrator request.
 See the \fBupdate node\fR command in the \fBscontrol\fR(1)
 man page or the \fBslurm.conf\fR(5) man page for more information.
 .TP
 \fBFAILING\fR
 The node is currently executing a job, but is expected to fail
 soon and is unavailable for use per system administrator request.
 See the \fBupdate node\fR command in the \fBscontrol\fR(1)
 man page or the \fBslurm.conf\fR(5) man page for more information.
 .TP
 \fBIDLE\fR
 The node is not allocated to any jobs and is available for use.
 .TP
 \fBMAINT\fR
 The node is currently in a reservation with a flag value of "maintainence".
 .TP
 \fBUNKNOWN\fR
 The SLURM controller has just started and the node's state
 has not yet been determined.

 .SH "ENVIRONMENT VARIABLES"
 .PP
 Some \fBsinfo\fR 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.)
 .TP 20

	.TP
	\fB\-p <partition>\fR, \fB\-\-partition=<partition>\fR
	Print information only about the specified partition.

	.TP
	\fB\-r\fR, \fB\-\-responding\fR
	If set only report state information for responding nodes.

	.TP
	\fB\-R\fR, \fB\-\-list\-reasons\fR
	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. \fB\-r\fR, \fB\-d\fR, \fB\-t\fR, \fB\-n\fR),
	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 \fB\-l\fR the output additionally includes
	the current node state.

	.TP
	\fB\-s\fR, \fB\-\-summarize\fR
	List only a partition state summary with no node state details.
	This is ignored if the \fB\-\-format\fR option is specified.

	.TP
	\fB\-S <sort_list>\fR, \fB\-\-sort=<sort_list>\fR
	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 preceeded
	by "+" or "\-" for assending (default) and desending order
	respectively. The partition field specification, "P", may be
	preceeded by a "#" to report partitions in the same order that
	they appear in SLURM's configuration file, \fBslurm.conf\fR.
	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 \fB\-\-Node\fB option is selected, the
	default sort value is "N" (increasing node name).

	.TP
	\fB\-t <states>\fR , \fB\-\-states=<states>\fR
	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 \fB\-\-dead\fR and \fB\-\-responding\fR options may be
	used to filtering nodes by the responding flag.

	.TP
	\fB\-\-usage\fR
	Print a brief message listing the \fBsinfo\fR options.

	.TP
	\fB\-v\fR, \fB\-\-verbose\fR
	Provide detailed event logging through program execution.

	.TP
	\fB\-V\fR, \fB\-\-version\fR
	Print version information and exit.

	node count are the same. \fBinfinite\fR is used to identify
	partitions without a maximum node count.
	.TP
	\fBTIMELIMIT\fR
	Maximum time limit for any user job in
	days\-hours:minutes:seconds. \fBinfinite\fR is used to identify

	Is the ability to allocate resources in this partition
	restricted to user root, \fByes\fR or \fBno\fR.
	.TP
	\fBSHARE\fR
	Will jobs allocated resources in this partition share those
	resources.
	\fBno\fR indicates resources are never shared.
	\fBexclusive\fR indicates whole nodes are dedicated to jobs
	(equivalent to srun \-\-exclusive option, may be used even
	with shared/cons_res managing individual processors).
	\fBforce\fR indicates resources are always available to be shared.
	\fByes\fR indicates resource may be shared or not
	per job's resource allocation.
	.TP
	\fBSTATE\fR
	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,

	Note that the suffix "*" identifies nodes that are presently
	not responding.
	.TP
	\fBTMP_DISK\fR
	Size of temporary disk space in megabytes on these nodes.

	.SH "NODE STATE CODES"
	.PP
	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 \fBDOWN\fR state (except in the case of
	\fBCOMPLETING\fR, \fBDRAINED\fR, \fBDRAINING\fR,
	\fBFAIL\fR, \fBFAILING\fR 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).
	.TP 12
	\fBALLOCATED\fR
	The node has been allocated to one or more jobs.
	.TP
	\fBALLOCATED+\fR
	The node is allocated to one or more active jobs plus
	one or more jobs are in the process of COMPLETING.
	.TP
	\fBCOMPLETING\fR
	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 \fBEpilog\fR
	parameter description in the \fBslurm.conf\fR man page for
	more information.
	.TP
	\fBDOWN\fR
	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 \fBReturnToService\fR

	for more information.
	.TP
	\fBDRAINING\fR
	The node is currently executing a job, but will not be allocated
	to additional jobs. The node state will be changed to state
	\fBDRAINED\fR when the last job on it completes. Nodes enter
	this state per system administrator request. See the \fBupdate
	node\fR command in the \fBscontrol\fR(1) man page or the
	\fBslurm.conf\fR(5) man page for more information.
