1sinfo(1) Slurm Commands sinfo(1)
2
6 sinfo - view information about Slurm nodes and partitions.
7
10 sinfo [OPTIONS...]
11
13 sinfo is used to view partition and node information for a system run‐
14 ning Slurm.
15
18 -a, --all
19 Display information about all partitions. This causes informa‐
20 tion to be displayed about partitions that are configured as
21 hidden and partitions that are unavailable to user's group.
22 -d, --dead
25 If set only report state information for non-responding (dead)
26 nodes.
27 -e, --exact
30 If set, do not group node information on multiple nodes unless
31 their configurations to be reported are identical. Otherwise cpu
32 count, memory size, and disk space for nodes will be listed with
33 the minimum value followed by a "+" for nodes with the same par‐
34 tition and state (e.g., "250+").
35 --federation
38 Show all partitions from the federation if a member of one.
39 -h, --noheader
42 Do not print a header on the output.
43 --help Print a message describing all sinfo options.
46 --hide Do not display information about hidden partitions. By default,
49 partitions that are configured as hidden or are not available to
50 the user's group will not be displayed (i.e. this is the default
51 behavior).
52 -i <seconds>, --iterate=<seconds>
55 Print the state on a periodic basis. Sleep for the indicated
56 number of seconds between reports. By default, prints a time
57 stamp with the header.
58 --local
61 Show only jobs local to this cluster. Ignore other clusters in
62 this federation (if any). Overrides --federation.
63 -l, --long
66 Print more detailed information. This is ignored if the --for‐
67 mat option is specified.
68 -M, --clusters=<string>
71 Clusters to issue commands to. Multiple cluster names may be
72 comma separated. A value of of 'all' will query to run on all
73 clusters. Note that the SlurmDBD must be up for this option to
74 work properly. This option implicitly sets the --local option.
75 -n <nodes>, --nodes=<nodes>
78 Print information only about the specified node(s). Multiple
79 nodes may be comma separated or expressed using a node range
80 expression. For example "linux[00-07]" would indicate eight
81 nodes, "linux00" through "linux07." Performance of the command
82 can be measurably improved for systems with large numbers of
83 nodes when a single node name is specified.
84 --noconvert
87 Don't convert units from their original type (e.g. 2048M won't
88 be converted to 2G).
89 -N, --Node
92 Print information in a node-oriented format with one line per
93 node and partition. That is, if a node belongs to more than one
94 partition, then one line for each node-partition pair will be
95 shown. If --partition is also specified, then only one line per
96 node in this partition is shown. The default is to print infor‐
97 mation in a partition-oriented format. This is ignored if the
98 --format option is specified.
99 -o <output_format>, --format=<output_format>
102 Specify the information to be displayed using an sinfo format
103 string. Format strings transparently used by sinfo when running
104 with various options are
105 default "%#P %.5a %.10l %.6D %.6t %N"
107 --summarize "%#P %.5a %.10l %.16F %N"
109 --long "%#P %.5a %.10l %.10s %.4r %.8h %.10g %.6D %.11T
111 %N"
112 --Node "%#N %.6D %#P %6t"
114 --long --Node "%#N %.6D %#P %.11T %.4c %.8z %.6m %.8d %.6w %.8f
116 %20E"
117 --list-reasons "%20E %9u %19H %N"
119 --long --list-reasons
121 "%20E %12U %19H %6t %N"
122 In the above format strings, the use of "#" represents the maxi‐
125 mum length of any partition name or node list to be printed. A
126 pass is made over the records to be printed to establish the
127 size in order to align the sinfo output, then a second pass is
128 made over the records to print them. Note that the literal
129 character "#" itself is not a valid field length specification,
130 but is only used to document this behaviour.
131 The field specifications available include:
133 %all Print all fields available for this data type with a ver‐
135 tical bar separating each field.

417 ple partitions are separated by commas.
418 -r, --responding
421 If set only report state information for responding nodes.
422 -R, --list-reasons
425 List reasons nodes are in the down, drained, fail or failing
426 state. When nodes are in these states Slurm supports optional
427 inclusion of a "reason" string by an administrator. This option
428 will display the first 20 characters of the reason field and
429 list of nodes with that reason for all nodes that are, by
430 default, down, drained, draining or failing. This option may be
431 used with other node filtering options (e.g. -r, -d, -t, -n),
432 however, combinations of these options that result in a list of
433 nodes that are not down or drained or failing will not produce
434 any output. When used with -l the output additionally includes
435 the current node state.
436 -s, --summarize
439 List only a partition state summary with no node state details.
440 This is ignored if the --format option is specified.
441 -S <sort_list>, --sort=<sort_list>
444 Specification of the order in which records should be reported.
445 This uses the same field specification as the <output_format>.
446 Multiple sorts may be performed by listing multiple sort fields
447 separated by commas. The field specifications may be preceded
448 by "+" or "-" for ascending (default) and descending order
449 respectively. The partition field specification, "P", may be
450 preceded by a "#" to report partitions in the same order that
451 they appear in Slurm's configuration file, slurm.conf. For
452 example, a sort value of "+P,-m" requests that records be
453 printed in order of increasing partition name and within a par‐
454 tition by decreasing memory size. The default value of sort is
455 "#P,-t" (partitions ordered as configured then decreasing node
456 state). If the --Node option is selected, the default sort
457 value is "N" (increasing node name).
458 -t <states> , --states=<states>
461 List nodes only having the given state(s). Multiple states may
462 be comma separated and the comparison is case insensitive. Pos‐
463 sible values include (case insensitive): ALLOC, ALLOCATED, COMP,
464 COMPLETING, DOWN, DRAIN (for node in DRAINING or DRAINED
465 states), DRAINED, DRAINING, FAIL, FUTURE, FUTR, IDLE, MAINT,
466 MIX, MIXED, NO_RESPOND, NPC, PERFCTRS, POWER_DOWN, POWER‐
467 ING_DOWN, POWER_UP, RESV, RESERVED, UNK, and UNKNOWN. By
468 default nodes in the specified state are reported whether they
469 are responding or not. The --dead and --responding options may
470 be used to filtering nodes by the responding flag.
471 -T, --reservation
474 Only display information about Slurm reservations.
475 --usage
478 Print a brief message listing the sinfo options.
479 -v, --verbose
482 Provide detailed event logging through program execution.
483 -V, --version
486 Print version information and exit.
487
490 AVAIL Partition state: up or down.

505 named groups. all indicates that all groups may use this parti‐
506 tion.
507 JOB_SIZE
509 Minimum and maximum node count that can be allocated to any user
510 job. A single number indicates the minimum and maximum node
511 count are the same. infinite is used to identify partitions
512 without a maximum node count.
513 TIMELIMIT
515 Maximum time limit for any user job in days-hours:minutes:sec‐
516 onds. infinite is used to identify partitions without a job
517 time limit.
518 MEMORY Size of real memory in megabytes on these nodes.
520 NODELIST
522 Names of nodes associated with this configuration/partition.
523 NODES Count of nodes with this particular configuration.
525 NODES(A/I)
527 Count of nodes with this particular configuration by node state
528 in the form "available/idle".
529 NODES(A/I/O/T)
531 Count of nodes with this particular configuration by node state
532 in the form "available/idle/other/total".
533 PARTITION
535 Name of a partition. Note that the suffix "*" identifies the
536 default partition.
537 PORT Local TCP port used by slurmd on the node.
539 ROOT Is the ability to allocate resources in this partition
541 restricted to user root, yes or no.
542 OVERSUBSCRIBE
544 Will jobs allocated resources in this partition oversubscribe
545 those compute resources (i.e. CPUs). no indicates resources are
546 never oversubscribed. exclusive indicates whole nodes are dedi‐
547 cated to jobs (equivalent to srun --exclusive option, may be
548 used even with select/cons_res managing individual processors).
549 force indicates resources are always available to be oversub‐
550 scribed. yes indicates resource may be oversubscribed or not
551 per job's resource allocation.
552 STATE State of the nodes. Possible states include: allocated, com‐
554 pleting, down, drained, draining, fail, failing, future, idle,
555 maint, mixed, perfctrs, power_down, power_up, reserved, and
556 unknown plus Their abbreviated forms: alloc, comp, down, drain,
557 drng, fail, failg, futr, idle, maint, mix, npc, pow_dn, pow_up,
558 resv, and unk respectively. Note that the suffix "*" identifies
559 nodes that are presently not responding.
560 TMP_DISK
562 Size of temporary disk space in megabytes on these nodes.
563
566 Node state codes are shortened as required for the field size. These
567 node states may be followed by a special character to identify state
568 flags associated with the node. The following node sufficies and
569 states are used:
570 * The node is presently not responding and will not be allocated any
572 new work. If the node remains non-responsive, it will be placed in
573 the DOWN state (except in the case of COMPLETING, DRAINED, DRAIN‐
574 ING, FAIL, FAILING nodes).
575 ~ The node is presently in a power saving mode (typically running at
577 reduced frequency).
578 # The node is presently being powered up or configured.
580 % The node is presently being powered down.
582 $ The node is currently in a reservation with a flag value of "main‐
584 tenance".
585 @ The node is pending reboot.
587 ALLOCATED The node has been allocated to one or more jobs.
589 ALLOCATED+ The node is allocated to one or more active jobs plus one
591 or more jobs are in the process of COMPLETING.
592 COMPLETING All jobs associated with this node are in the process of
594 COMPLETING. This node state will be removed when all of
595 the job's processes have terminated and the Slurm epilog
596 program (if any) has terminated. See the Epilog parameter
597 description in the slurm.conf man page for more informa‐
598 tion.
599 DOWN The node is unavailable for use. Slurm can automatically
601 place nodes in this state if some failure occurs. System
602 administrators may also explicitly place nodes in this
603 state. If a node resumes normal operation, Slurm can auto‐
604 matically return it to service. See the ReturnToService and
605 SlurmdTimeout parameter descriptions in the slurm.conf(5)
606 man page for more information.
607 DRAINED The node is unavailable for use per system administrator
609 request. See the update node command in the scontrol(1)
610 man page or the slurm.conf(5) man page for more informa‐
611 tion.
612 DRAINING The node is currently executing a job, but will not be
614 allocated to additional jobs. The node state will be
615 changed to state DRAINED when the last job on it completes.
616 Nodes enter this state per system administrator request.
617 See the update node command in the scontrol(1) man page or
618 the slurm.conf(5) man page for more information.
619 FAIL The node is expected to fail soon and is unavailable for
621 use per system administrator request. See the update node
622 command in the scontrol(1) man page or the slurm.conf(5)
623 man page for more information.
624 FAILING The node is currently executing a job, but is expected to
626 fail soon and is unavailable for use per system administra‐
627 tor request. See the update node command in the scon‐
628 trol(1) man page or the slurm.conf(5) man page for more
629 information.
630 FUTURE The node is currently not fully configured, but expected to
632 be available at some point in the indefinite future for
633 use.
634 IDLE The node is not allocated to any jobs and is available for
636 use.
637 MAINT The node is currently in a reservation with a flag value of
639 "maintainence".
640 REBOOT The node is currently scheduled to be rebooted.
642 MIXED The node has some of its CPUs ALLOCATED while others are
644 IDLE.
645 PERFCTRS (NPC)
647 Network Performance Counters associated with this node are
648 in use, rendering this node as not usable for any other
649 jobs
650 POWER_DOWN The node is currently powered down and not capable of run‐
652 ning any jobs.
653 POWERING_DOWN
655 The node is currently powering down and not capable of run‐
656 ning any jobs.
657 POWER_UP The node is currently in the process of being powered up.
659 RESERVED The node is in an advanced reservation and not generally
661 available.
662 UNKNOWN The Slurm controller has just started and the node's state
664 has not yet been determined.
665
668 Some sinfo options may be set via environment variables. These environ‐
669 ment variables, along with their corresponding options, are listed
670 below. (Note: Commandline options will always override these settings.)
671 SINFO_ALL -a, --all
673 SINFO_FEDERATION Same as --federation
675 SINFO_FORMAT -o <output_format>, --format=<output_format>
677 SINFO_LOCAL Same as --local
679 SINFO_PARTITION -p <partition>, --partition=<partition>
681 SINFO_SORT -S <sort>, --sort=<sort>
683 SLURM_CLUSTERS Same as --clusters
685 SLURM_CONF The location of the Slurm configuration file.
687 SLURM_TIME_FORMAT Specify the format used to report time stamps. A
689 value of standard, the default value, generates
690 output in the form
691 "year-month-dateThour:minute:second". A value of
692 relative returns only "hour:minute:second" if the
693 current day. For other dates in the current year
694 it prints the "hour:minute" preceded by "Tomorr"
695 (tomorrow), "Ystday" (yesterday), the name of the
696 day for the coming week (e.g. "Mon", "Tue", etc.),
697 otherwise the date (e.g. "25 Apr"). For other
698 years it returns a date month and year without a
699 time (e.g. "6 Jun 2012"). All of the time stamps
700 use a 24 hour format.
701 A valid strftime() format can also be specified.
703 For example, a value of "%a %T" will report the day
704 of the week and a time stamp (e.g. "Mon 12:34:56").
