smap(1)

NAME
smap - graphically view information about Slurm jobs, partitions, and set configurations parameters.

SYNOPSIS
smap [OPTIONS...]

DESCRIPTION
smap is used to graphically view job, partition and node information for a system running Slurm. Note that information about nodes and partitions to which you lack access will always be displayed to avoid obvious gaps in the output. This is equivalent to the --all option of the sinfo and squeue commands.

OPTIONS

-c, --commandline
    Print output to the commandline, no curses.

-D <option>, --display=<option>
    sets the display mode for smap, showing relevant information about the selected view and displaying a corresponding node chart. Note that unallocated nodes are indicated by a '.' and nodes in the DOWN, DRAINED or FAIL state by a '#'. When the --iterate=<seconds> option is also selected, you can switch displays by typing a different letter from the list below.

    j   Displays information about jobs running on system.

    r   Display information about advanced reservations. While all current and future reservations will be listed, only currently active reservations will appear on the node map.

    s   Displays information about slurm partitions on the system

-h, --noheader
    Do not print a header on the output.

-H, --show_hidden
    Display hidden partitions and their jobs.

--help,
    Print a message describing all smap options.

-i <seconds> , --iterate=<seconds>
    Print the state on a periodic basis. Sleep for the indicated number of seconds between reports. User can exit at anytime by typing 'q' or hitting the return key. If user is in configure mode type 'exit' to exit program, 'quit' to exit configure mode.

-M, --clusters=<string>
    Clusters to issue commands to. Note that the SlurmDBD must be up for this option to work properly.

-n, --nodes
    Only show objects with these nodes.

-Q, --quiet
    Avoid printing error messages.

--usage
    Print a brief message listing the smap options.

-V , --version
    Print version information and exit.

INTERACTIVE OPTIONS
When using smap in curses mode and when the --iterate=<seconds> option is also selected, you can scroll through the different windows using the arrow keys. The up and down arrow keys scroll the window containing the grid, and the left and right arrow keys scroll the window containing the text information.

With the iterate option selected, you can use any of the options available to the -D option listed above (except 'c') to change screens. You can also hide or make visible hidden partitions by pressing 'h' at any moment.

OUTPUT FIELD DESCRIPTIONS

ACCESS_CONTROL
    Identifies the users or bank accounts which can use this advanced reservation. A prefix of "A:" indicates that the following account names may use this reservation. A prefix of "U:" indicates that the following user names may use this reservation.

AVAIL
    Partition state: up or down.

END_TIME
    The time when an advanced reservation ended.

ID  Key to identify the nodes associated with this entity in the node chart.

NAME
    Name of the job or advanced reservation.

NODELIST
    Names of nodes associated with this configuration, partition or reservation.

NODES
    Count of nodes with this particular configuration.

PARTITION
    Name of a partition. Note that the suffix "*" identifies the default partition.

ST  State of a job in compact form. Possible states include: PD (pending), R (running), S (suspended), CD (completed), CF (configuring), CG (completing), F (failed), TO (timeout), and NF (node failure). See JOB STATE CODES section below for more information.

START_TIME
    The time when an advanced reservation started.

STATE
    State of the nodes. Possible states include: allocated, completing, down, drained, draining, fail, failing, idle, and unknown plus their abbreviated forms: alloc, comp, down, drain, drng, fail, failg, idle, and unk respectively. Note that the suffix "*" identifies nodes that are presently not responding. See NODE STATE CODES section below for more information.

TIMELIMIT
    Maximum time limit for any user job in days-hours:minutes:seconds. infinite is used to identify jobs or partitions without a job time limit.

TOPOGRAPHY INFORMATION

The node chart is designed to indicate relative locations of
    the nodes. On most Linux clusters this will represent a one-dimensional array of nodes. Larger clusters will utilize multiple as needed with right side of one line being logically followed by the left side of the next line.

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 associated with the node. The following node sufficies 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, FAILING nodes).

~   The node is presently in a power saving mode (typically running at reduced frequency).

#   The node is presently being powered up or configured.

$   The node is currently in a reservation with a flag value of "maintenance".

@   The node is pending reboot.

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.

COMPLETING
    All jobs associated with this node are in the process of COMPLETING. This node state will be removed when all of the job's processes have terminated and the Slurm epilog program (if any) has terminated. See the Epilog parameter description in the slurm.conf 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 administrators 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 information.

DRAINED
    The node 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.

DRAINING
    The node is currently executing a job, but will not be allocated to 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 request. See the update node command in the scontrol(1) man page or the slurm.conf(5) man page for more information.

IDLE
    The node is not allocated to any jobs and is available for use.

MAINT
    The node is currently in a reservation with a flag value of "maintainence".

REBOOT
    The node is currently scheduled to be rebooted.

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

JOB STATE CODES
Jobs typically pass through several states in the course of their execution. The typical states are PENDING, RUNNING, SUSPENDED, COMPLETING, and COMPLETED. An explanation of each state follows.

BF  BOOT_FAIL
    Job terminated due to launch failure, typically due to a hardware failure (e.g. unable to boot the node or block and the job can not be requeued).

CA  CANCELLED
    Job was explicitly cancelled by the user or system administrator. The job may or may not have been initiated.

CD  COMPLETED
    Job has terminated all processes on all nodes with an exit code of zero.

CG  COMPLETING
    Job is in the process of completing. Some processes on some nodes may still be active.

CF  CONFIGURING
    Job has been allocated resources, but are waiting for them to become ready for use (e.g. booting).

F   FAILED
    Job terminated with non-zero exit code or other failure condition.

NF  NODE_FAIL
    Job terminated due to failure of one or more allocated nodes.

PD  PENDING
    Sibling job (in federation) revoked.

PR  PREEMPTED
    Job terminated due to preemption.

RV  REVOKED
    Job currently has an allocation.

R   RUNNING
    Job currently has an allocation.

SI  SIGNALING
    Signal of job currently in progress.

SO  STAGE_OUT
    Staging out data after job completion.

SE  SPECIAL_EXIT
    The job was requeued in a special state. This state can be set by users, typically in EpilogSlurmctld, if the job has terminated with a particular exit value.

ST  STOPPED
    Job has an allocation, but execution has been stopped with SIGSTOP signal. CPUS have been retained by this job.

S   SUSPENDED
    Job has an allocation, but execution has been suspended and CPUs have been released for other jobs.

TO  TIMEOUT
    Job terminated upon reaching its time limit.

ENVIRONMENT VARIABLES
The following environment variables can be used to override settings compiled into smap.

SLURM_CONF
    The location of the Slurm configuration file.
