    .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 partitions. This causes information to be
    displayed about partitions that are configured as hidden and partitions that
    are unavailable to user's group.

    .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\-\-federation\fR
    Show all partitions from the federation if a member of one.

    .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\-\-local\fR
    Show only jobs local to this cluster. Ignore other clusters in this federation
    (if any). Overrides \-\-federation.
    \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."
    Performance of the command can be measurably improved for systems with large
    numbers of nodes when a single node name is specified.

    .TP
    \fB\-\-noconvert\fR
    Don't convert units from their original type (e.g. 2048M won't be converted to
    2G).

    .TP
    \fB\-N\fR, \fB\-\-Node\fR
    Print information in a node\-oriented format with one line per node
    and partition. That is, if a node belongs to more than one partition, then one
    line for each node\-partition pair will be shown.
    If \fB\-\-partition\fR is also specified, then only one line per node in this
    partition is shown.
    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

    \fBweight\fR
    Scheduling weight of the nodes.
    When nodes are in these states Slurm supports optional inclusion
    of a "reason" string by an administrator.
    This option will display the first 20 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 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, \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, FUTURE, FUTR,
    IDLE, MAINT, MIX, MIXED, NO_RESPOND, NPC, PERFCTRS,
    POWER_DOWN, POWERING_DOWN, POWER_UP, RESV, RESERVED, 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\-T\fR, \fB\-\-reservation\fR
    Only display information about Slurm reservations.
    .TP
    \fBAVAIL\fR

    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

    state in the form "available/idle/other/total".
    .TP
    \fBno\fR indicates resources are never oversubscribed.
    \fBexclusive\fR indicates whole nodes are dedicated to jobs
    (equivalent to srun \-\-exclusive option, may be used even
    with select/cons_res managing individual processors).
    \fBforce\fR indicates resources are always available to be oversubscribed.
    \fByes\fR indicates resource may be oversubscribed or not
    per job's resource allocation.
    .TP
    \fBSTATE\fR
    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.
    .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.
    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:
    .TP 4

    .TP
    \fBSLURM_TIME_FORMAT\fR
    Specify the format used to report time stamps. A value of \fIstandard\fR, the
    default value, generates output in the form "year\-month\-dateThour:minute:second".
    A value of \fIrelative\fR 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").
