sinfo(1) Slurm Commands sinfo(1) NAME sinfo - View information about Slurm nodes and partitions. SYNOPSIS sinfo [OPTIONS...] DESCRIPTION sinfo is used to view partition and node information for a system running Slurm. OPTIONS -a, --all Display information about all partitions. This causes information to be displayed about partitions that are configured as hidden and par- titions that are unavailable to the user's group. -M, --clusters=<string> Clusters to issue commands to. Multiple cluster names may be comma separated. A value of 'all' will query all clusters. Note that the slurmdbd must be up for this option to work properly, unless running in a federation with either FederationParameters=fed_display config- ured or the --federation option set. This option implicitly sets the --local option. -d, --dead Only show nodes that have unexpectedly stopped responding. This may not show nodes in a POWERED_DOWN state since they are expected to be down. -e, --exact 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 mini- mum value followed by a "+" for nodes with the same partition and state (e.g. "250+"). --federation Show all partitions from the federation if a member of one. -F, --future Report nodes in FUTURE state. -o, --format=<output_format> Specify the information to be displayed using an sinfo format string. If the command is executed in a federated cluster environ- ment and information about more than one cluster is to be displayed and the -h, --noheader option is used, then the cluster name will be displayed before the default output formats shown below. Format strings transparently used by sinfo when running with various op- tions are: default "%#P %.5a %.10l %.6D %.6t %N" --summarize "%#P %.5a %.10l %.16F %N" --long "%#P %.5a %.10l %.10s %.4r %.8h %.10g %.6D %.11T %.11i %N" --Node "%#N %.6D %#P %6t" --long --Node "%#N %.6D %#P %.11T %.4c %.8z %.6m %.8d %.6w %.8f %20E" --list-reasons "%20E %9u %19H %N" --long --list-reasons "%20E %12U %19H %6t %N" In the above format strings, the use of "#" represents the maximum length of any partition name or node list to be printed. A pass is made over the records to be printed to establish the size in order to align the sinfo output, then a second pass is made over the records to print them. Note that the literal character "#" itself is not a valid field length specification, but is only used to docu- ment this behavior. The format of each field is "%[[.]size]type[suffix]" size Minimum field size. If no size is specified, whatever is needed to print the information will be used. . Indicates the output should be right justified and size must be specified. By default output is left justified. suffix Arbitrary string to append to the end of the field. Valid type specifications include: %all Print all fields available for this data type with a vertical bar separating each field. %a State/availability of a partition. %A Number of nodes by state in the format "allocated/idle". Do not use this with a node state option ("%t" or "%T") or the different node states will be placed on separate lines. %b Features currently active on the nodes, also see %f. %B The max number of CPUs per node available to jobs in the par- tition. %c Number of CPUs per node. %C Number of CPUs by state in the format "allo- cated/idle/other/total". Do not use this with a node state op- tion ("%t" or "%T") or the different node states will be placed on separate lines. %d Size of temporary disk space per node in mebibytes. %D Number of nodes. %e The total memory, in MiB, currently free on the node as re- ported by the OS. This value is for informational use only and is not used for scheduling. %E The reason a node is unavailable (down, drained, or draining states). %f Features available the nodes, also see %b. %F Number of nodes by state in the format "allo- cated/idle/other/total". Note the use of this format option with a node state format option ("%t" or "%T") will result in the different node states being be reported on separate lines. %g Groups which may use the nodes. %G Generic resources (gres) associated with the nodes. %h Print the OverSubscribe setting for the partition. %H Print the timestamp of the reason a node is unavailable. %i If a node is in an advanced reservation print the name of that reservation. %I Partition job priority weighting factor. %l Maximum time for any job in the format "days-hours:min- utes:seconds" %L Default time for any job in the format "days-hours:min- utes:seconds" %m Size of memory per node in mebibytes. %M PreemptionMode. %n List of node hostnames. %N List of node names. %o List of node communication addresses. %O CPU load of a node as reported by the OS. %p Partition scheduling tier priority. %P Partition name followed by "*" for the default partition, also see %R. %r Only user root may initiate jobs, "yes" or "no". %R Partition name, also see %P. %s Maximum job size in nodes. %S Allowed allocating nodes. %t State of nodes, compact form. %T State of nodes, extended form. %u Print the user name of who set the reason a node is unavail- able. %U Print the user name and uid of who set the reason a node is unavailable. %v Print the running slurmd version. If reporting on a node list, print the version of the first node in the list. %V Print the cluster name if running in a federation. %w Scheduling weight of the nodes. %X Number of sockets per node. %Y Number of cores per socket. %Z Number of threads per core. %z Extended processor information: number of sockets, cores, threads (S:C:T) per node. -O, --Format=<output_format> Specify the information to be displayed. Also see the -o <out- put_format>, --format=<output_format> option (which supports greater flexibility in formatting, but does not support access to all fields because we ran out of letters). Requests a comma separated list of job information to be displayed. The format of each field is "type[:[.][size][suffix]]" size The maximum field size. If no size is specified, 20 char- acters will be allocated to print the information. . Indicates the output should be right justified and size must be specified. By default, output is left justified. suffix Arbitrary string to append to the end of the field. Valid type specifications include: All Print all fields available in the -o format for this data type with a vertical bar separating each field. AllocMem Prints the amount of allocated memory on a node. AllocNodes Allowed allocating nodes. Available State/availability of a partition. Cluster Print the cluster name if running in a federation. Comment Comment. (Arbitrary descriptive string) Cores Number of cores per socket. CPUs Number of CPUs per node. CPUsLoad CPU load of a node as reported by the OS. CPUsState Number of CPUs by state in the format "allo- cated/idle/other/total". Do not use this with a node state option ("%t" or "%T") or the different node states will be placed on separate lines. DefaultTime Default time for any job in the format "days-hours:min- utes:seconds". Disk Size of temporary disk space per node in mebibytes. Extra Arbitrary string on the node. Features Features available on the nodes. Also see features_act. features_act Features currently active on the nodes. Also see features.

User Print the user name of who set the reason a node is unavail- able. UserLong Print the user name and uid of who set the reason a node is unavailable. Version Print the running slurmd version. If reporting on a node list, print the version of the first node in the list. Weight Scheduling weight of the nodes. --help Print a message describing all sinfo options. --hide 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. -i, --iterate=<seconds> 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. --json, --json=list, --json=<data_parser> Dump information as JSON using the default data_parser plugin or ex- plicit data_parser with parameters. All information is dumped, even if it would normally not be. Sorting and formatting arguments passed to other options are ignored; however, most filtering arguments are still used. -R, --list-reasons 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 op- tions (e.g. -r, -d, -t, -n), however, combinations of these options that result in a list of nodes that are not down or drained or fail- ing will not produce any output. When used with -l the output addi- tionally includes the current node state. --local Show only jobs local to this cluster. Ignore other clusters in this federation (if any). Overrides --federation. -l, --long Print more detailed information. This is ignored if the --format option is specified. --noconvert Don't convert units from their original type (e.g. 2048M won't be converted to 2G). -N, --Node Print information in a node-oriented format with one line per node and partition. That is, if a node belongs to more than one parti- tion, then one line for each node-partition pair will be shown. If --partition is also specified, then only one line per node in this partition is shown. The default is to print information in a parti- tion-oriented format. This is ignored if the --format option is specified. -n, --nodes=<nodes> 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 clus- ters. -h, --noheader Do not print a header on the output. -p, --partition=<partition> Print information about the node(s) in the specified partition(s). Multiple partitions are separated by commas. -T, --reservation Only display information about Slurm reservations. NOTE: This option causes sinfo to ignore most other options, which are focused on partition and node information. -r, --responding Exclude any nodes that have unexpectedly stopped responding. This is the opposite of --dead. -S, --sort=<sort_list> Specification of the order in which records should be reported. This uses the same field specification as the <output_format>. Mul- tiple sorts may be performed by listing multiple sort fields sepa- rated 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 re- port partitions in the same order that they appear in Slurm's con- figuration file, slurm.conf. 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 de- creasing node state). If the --Node option is selected, the default sort value is "N" (increasing node name). -t, --states=<states> List nodes only having the given state(s). Multiple states may be comma separated and the comparison is case insensitive. If the states are separated by '+', then the nodes must be in all states. The state can be prefixed with '~' which will invert the result of match. Possible values include (case insensitive): ALLOC, ALLO- CATED, BLOCKED, CLOUD, COMP, COMPLETING, DOWN, DRAIN (for node in DRAINING or DRAINED states), DRAINED, DRAINING, FAIL, FUTURE, FUTR, IDLE, MAINT, MIX, MIXED, NO_RESPOND, NPC, PERFCTRS, PLANNED, POWER_DOWN, POWERING_DOWN, POWERED_DOWN, POWERING_UP, REBOOT_ISSUED, REBOOT_REQUESTED, RESV, RESERVED, UNK, and UNKNOWN. By default nodes in the specified state are reported whether they are respond- ing or not. The --dead and --responding options may be used to fil- ter nodes by the corresponding flag. -s, --summarize List only a partition state summary with no node state details. This is ignored if the --format option is specified. --usage Print a brief message listing the sinfo options. -v, --verbose Provide detailed event logging through program execution. -V, --version Print version information and exit. --yaml, --yaml=list, --yaml=<data_parser> Dump information as YAML using the default data_parser plugin or ex- plicit data_parser with parameters. All information is dumped, even if it would normally not be. Sorting and formatting arguments passed to other options are ignored; however, most filtering arguments are still used. OUTPUT FIELD DESCRIPTIONS AVAIL Partition state. Can be either up, down, drain, or inact (for INAC- TIVE). See the partition definition's State parameter in the slurm.conf(5) man page for more information. CPUS Count of CPUs (processors) on these nodes. S:C:T Count of sockets (S), cores (C), and threads (T) on these nodes. SOCKETS Count of sockets on these nodes. CORES Count of cores on these nodes. THREADS Count of threads on these nodes. GROUPS Resource allocations in this partition are restricted to the named groups. all indicates that all groups may use this partition. JOB_SIZE 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. infinite is used to identify partitions without a max- imum node count. TIMELIMIT Maximum time limit for any user job in days-hours:minutes:seconds. infinite is used to identify partitions without a job time limit. MEMORY Size of real memory in mebibytes on these nodes. NODELIST Names of nodes associated with this particular configuration. NODES Count of nodes with this particular configuration. NODES(A/I) Count of nodes with this particular configuration by node state in the form "allocated/idle". NODES(A/I/O/T) Count of nodes with this particular configuration by node state in the form "allocated/idle/other/total". PARTITION Name of a partition. Note that the suffix "*" identifies the default partition. PORT Local TCP port used by slurmd on the node. ROOT Is the ability to allocate resources in this partition restricted to user root, yes or no. OVERSUBSCRIBE Whether the partition allows more than one job at a time on the same resource (node, socket, or core per SelectTypeParameters), and the maximum share when applicable. NO: no sharing, only one job per resource. YES:n: sharing allowed when the job requests --oversubscribe, up to n jobs per resource. FORCE:n: sharing always allowed, up to n jobs per resource (jobs cannot opt out). STATE State of the nodes. Possible states include: allocated, blocked, completing, down, drained, draining, fail, failing, future, idle, maint, mixed, perfctrs, planned, power_down, power_up, reserved, and unknown. Their abbreviated forms are: alloc, block, comp, down, drain, drng, fail, failg, futr, idle, maint, mix, npc, plnd, pow_dn, pow_up, resv, and unk respectively. NOTE: The suffix "*" identifies nodes that are presently not re- sponding. TMP_DISK Size of temporary disk space in mebibytes on these nodes. NODE STATE CODES 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 asso- ciated with the node. The following node suffixes and states are used: * 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 DOWN state (except in the case of COMPLETING, DRAINED, DRAINING, FAIL, FAIL- ING nodes). ~ The node is presently in powered off. # The node is presently being powered up or configured. ! The node is pending power down. % The node is presently being powered down. $ The node is currently in a reservation with a flag value of "mainte- nance". @ The node is pending reboot. ^ The node reboot was issued. - The node is planned by the backfill scheduler for a higher priority job. ALLOCATED The node has been allocated to one or more jobs. ALLOCATED+ The node is allocated to one or more active jobs plus one or more jobs are in the process of COMPLETING. BLOCKED The node has been blocked by exclusive topo job. COMPLETING All jobs associated with this node are in the process of COM- PLETING. This node state will be removed when all of the job's processes have terminated and the Slurm epilog program (if any) has terminated. While a node is in the COMPLETING state, it is not eligible for new job placement and no jobs will be sched- uled on it. See the Epilog parameter description in the slurm.conf(5) man page for more information. DOWN The node is unavailable for use. Slurm can automatically place nodes in this state if some failure occurs. System administra- tors may also explicitly place nodes in this state. If a node resumes normal operation, Slurm can automatically return it to service. See the ReturnToService and SlurmdTimeout parameter descriptions in the slurm.conf(5) man page for more informa- tion. DRAINED The node is unavailable for use per system administrator re- quest. See the update node command in the scontrol(1) man page or the slurm.conf(5) man page for more information. DRAINING The node is currently allocated a job, but will not be allo- cated additional jobs. The node state will be changed to state DRAINED when the last job on it completes. Nodes enter this state per system administrator request. See the update node command in the scontrol(1) man page or the slurm.conf(5) man page for more information. FAIL The node is expected to fail soon and is unavailable for use per system administrator request. See the update node command in the scontrol(1) man page or the slurm.conf(5) man page for more information. FAILING The node is currently executing a job, but is expected to fail soon and is unavailable for use per system administrator re- quest. See the update node command in the scontrol(1) man page or the slurm.conf(5) man page for more information. FUTURE The node is currently not fully configured, but expected to be available at some point in the indefinite future for use. IDLE The node is not allocated to any jobs and is available for use. INVAL The node did not register correctly with the controller. This happens when a node registers with less resources than config- ured in the slurm.conf file. The node will clear from this state with a valid registration (i.e. a slurmd restart is re- quired). MAINT The node is currently in a reservation with a flag value of "maintenance". REBOOT_ISSUED A reboot request has been sent to the agent configured to han- dle this request. REBOOT_REQUESTED A request to reboot this node has been made, but hasn't been handled yet. MIXED The node has some of its CPUs ALLOCATED while others are IDLE. Or the node has a suspended job allocated to some of its TRES (e.g. memory). PERFCTRS (NPC) Network Performance Counters associated with this node are in use, rendering this node as not usable for any other jobs PLANNED The node is planned by the backfill scheduler for a higher pri- ority job. POWER_DOWN The node is pending power down. POWERED_DOWN The node is currently powered down and not capable of running any jobs. POWERING_DOWN The node is in the process of powering down and not capable of running any jobs. POWERING_UP The node is in the process of being powered up. RESERVED The node is in an advanced reservation and not generally avail- able. UNKNOWN The Slurm controller has just started and the node's state has not yet been determined. PERFORMANCE Executing sinfo sends a remote procedure call to slurmctld. If enough calls from sinfo or other Slurm client commands that send remote procedure calls to the slurmctld daemon come in at once, it can result in a degradation of performance of the slurmctld daemon, possibly resulting in a denial of ser- vice. Do not run sinfo or other Slurm client commands that send remote procedure calls to slurmctld from loops in shell scripts or other programs. Ensure that programs limit calls to sinfo to the minimum necessary for the infor- mation you are trying to gather. ENVIRONMENT VARIABLES Some sinfo options may be set via environment variables. These environment variables, along with their corresponding options, are listed below. NOTE: Command line options will always override these settings. SINFO_ALL Same as -a, --all SINFO_FEDERATION Same as --federation SCONTROL_FUTURE -F, --future SINFO_FORMAT Same as -o <output_format>, --format=<output_format> SINFO_LOCAL Same as --local SINFO_PARTITION Same as -p <partition>, --partition=<partition> SINFO_SORT Same as -S <sort>, --sort=<sort> SLURM_CLUSTERS Same as --clusters SLURM_CONF The location of the Slurm configuration file. SLURM_DEBUG_FLAGS Specify debug flags for sinfo to use. See DebugFlags in the slurm.conf(5) man page for a full list of flags. The environment variable takes precedence over the set- ting in the slurm.conf. SLURM_JSON Control JSON serialization: compact Output JSON as compact as possible. pretty Output JSON in pretty format to make it more readable. SLURM_TIME_FORMAT Specify the format used to report time stamps. A value of standard, the default value, generates output in the form "year-month-dateThour:minute:second". A value of relative returns only "hour:minute:second" if the cur- rent day. For other dates in the current year it prints the "hour:minute" preceded by "Tomorr" (tomor- row), "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"). SLURM_YAML Control YAML serialization: compact Output YAML as compact as possible. pretty Output YAML in pretty format to make it more readable.
