Slurm Workload Manager -

    .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 the 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. Partitions
    that are configured as hidden or are not available to the user's group
    will not be displayed. 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 \fB\-\-federation\fR.
    \fB\-n <nodes>\fR, \fB\-\-nodes=<nodes>\fR
    Print information about the specified node(s).
    Multiple nodes may be comma separated or expressed using a
    node range expression (e.g. "linux[00\-17]")
    Limiting the query to just the relevant nodes can measurably improve the
    performance of the command for large clusters.

    .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.
    If the command is executed in a federated cluster environment and information
    about more than one cluster is to be displayed and the \fB\-h, \-\-noheader\fR
    option is used, then the cluster name will be displayed before the default
    output formats shown below.
    Format strings transparently used by \fBsinfo\fR when running with various
    options are:

    Print information only about the specified partition(s). Multiple partitions
    are separated by commas.

    .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 the 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\fR option is selected, the
    The \fB\-\-dead\fR and \fB\-\-responding\fR options may be
    used to filter nodes by the corresponding flag.

    .TP
    \fB\-T\fR, \fB\-\-reservation\fR
    Only display information about Slurm reservations.

    \fBNOTE\fR: This option causes \fBsinfo\fR to ignore most other options,
    which are focused on partition and node information.

    .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.

    .TP
    \fBOVERSUBSCRIBE\fR
    Whether jobs allocated resources in this partition can/will oversubscribe
    those compute resources (e.g. CPUs).
    \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, if requested by the job's
    resource allocation.

    \fBNOTE\fR: If OverSubscribe is set to FORCE or YES,
    the OversubScribe value will be appended to the output.

    parameter description in the \fBslurm.conf\fR(5) 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

    The node is currently executing a job, but will not be allocated
    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

    The Slurm controller has just started and the node's state
    has not yet been determined.

    .SH "PERFORMANCE"
    .PP
    Executing \fBsinfo\fR sends a remote procedure call to \fBslurmctld\fR. If
    enough calls from \fBsinfo\fR or other Slurm client commands that send remote
    procedure calls to the \fBslurmctld\fR daemon come in at once, it can result in
    a degradation of performance of the \fBslurmctld\fR daemon, possibly resulting
    in a denial of service.
    .PP
    Do not run \fBsinfo\fR or other Slurm client commands that send remote procedure
    calls to \fBslurmctld\fR from loops in shell scripts or other programs. Ensure
    that programs limit calls to \fBsinfo\fR to the minimum necessary for the
    information you are trying to gather.

    Specify the format used to report time stamps. A value of \fIstandard\fR, the

    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").
