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.

410 -p <partition>, --partition=<partition>
413 Print information only about the specified partition(s). Multi‐
414 ple partitions are separated by commas.
415 -r, --responding
418 If set only report state information for responding nodes.
419 -R, --list-reasons
422 List reasons nodes are in the down, drained, fail or failing
423 state. When nodes are in these states Slurm supports optional
424 inclusion of a "reason" string by an administrator. This option
425 will display the first 20 characters of the reason field and
426 list of nodes with that reason for all nodes that are, by
427 default, down, drained, draining or failing. This option may be
428 used with other node filtering options (e.g. -r, -d, -t, -n),
429 however, combinations of these options that result in a list of
430 nodes that are not down or drained or failing will not produce
431 any output. When used with -l the output additionally includes
432 the current node state.
433 -s, --summarize
436 List only a partition state summary with no node state details.
437 This is ignored if the --format option is specified.
438 -S <sort_list>, --sort=<sort_list>
441 Specification of the order in which records should be reported.
442 This uses the same field specification as the <output_format>.
443 Multiple sorts may be performed by listing multiple sort fields
444 separated by commas. The field specifications may be preceded
445 by "+" or "-" for ascending (default) and descending order
446 respectively. The partition field specification, "P", may be
447 preceded by a "#" to report partitions in the same order that
448 they appear in Slurm's configuration file, slurm.conf. For
449 example, a sort value of "+P,-m" requests that records be
450 printed in order of increasing partition name and within a par‐
451 tition by decreasing memory size. The default value of sort is
452 "#P,-t" (partitions ordered as configured then decreasing node
453 state). If the --Node option is selected, the default sort
454 value is "N" (increasing node name).
455 -t <states> , --states=<states>
458 List nodes only having the given state(s). Multiple states may
459 be comma separated and the comparison is case insensitive. Pos‐
460 sible values include (case insensitive): ALLOC, ALLOCATED, COMP,
461 COMPLETING, DOWN, DRAIN (for node in DRAINING or DRAINED
462 states), DRAINED, DRAINING, FAIL, FUTURE, FUTR, IDLE, MAINT,
463 MIX, MIXED, NO_RESPOND, NPC, PERFCTRS, POWER_DOWN, POWER_UP,
464 RESV, RESERVED, UNK, and UNKNOWN. By default nodes in the spec‐
465 ified state are reported whether they are responding or not.
466 The --dead and --responding options may be used to filtering
467 nodes by the responding flag.
468 -T, --reservation
471 Only display information about Slurm reservations.
472 --usage
475 Print a brief message listing the sinfo options.
476 -v, --verbose
479 Provide detailed event logging through program execution.
480 -V, --version
483 Print version information and exit.
484
487 AVAIL Partition state: up or down.

490 S:C:T Count of sockets (S), cores (C), and threads (T) on these nodes.
492 SOCKETS
494 Count of sockets on these nodes.
495 CORES Count of cores on these nodes.
497 THREADS

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