man smap (1): graphically view information about Slurm jobs, partitions, and set

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 (except 'c').

b: Displays information about BlueGene partitions on the system
c: Displays current BlueGene node states and allows users to configure the system. Type 'quit' to end the configure mode. Type 'exit' to end the configuration mode and exit smap.
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.

-I, --ionodes

Only show objects with these ionodes this support is only for bluegene systems. This should be used inconjuction with the '-n' option. Only specify the ionode number range here. Specify the node name with the '-n' option.

-M, --clusters=<string>

Clusters to issue commands to.

-n, --nodes

Only show objects with these nodes. If querying to the ionode level use the option '-I' in conjunction with this option.

-Q, --quiet

Avoid printing error messages.

-R <RACK_MIDPLANE_ID/XYZ>, --resolve=<RACK_MIDPLANE_ID/XYZ>

Returns the XYZ coords for a Rack/Midplane id or vice-versa.

To get the XYZ coord for a Rack/Midplane id input -R R101 where 10 is the rack and 1 is the midplane.

To get the Rack/Midplane id from a XYZ coord input -R 101 where X=1 Y=1 Z=1 with no leading 'R'.

--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.

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.

On BlueGene systems, the node chart will indicate the three
dimensional topography of the system.
The X dimension will increase from left to right on a given line.
The Y dimension will increase in planes from bottom to top.
The Z dimension will increase within a plane from the back
line to the front line of a plane.

CONFIGURATION INSTRUCTIONS

For Admin use. From this screen one can create a configuration file that is used to partition and wire the system into usable blocks.

OUTPUT

BG_BLOCK: BlueGene Block Name.
CONN: Connection Type: TORUS or MESH or SMALL (for small blocks).
ID: Key to identify the nodes associated with this entity in the node chart.
MODE: Mode Type: COPROCESS or VIRTUAL.

INPUT COMMANDS

resolve <RACK_MIDPLANE_ID/XYZ>

Returns the XYZ coords for a Rack/Midplane id or vice-versa.

To get the XYZ coord for a Rack/Midplane id input -R R101 where 10 is the rack and 1 is the midplane.

To get the Rack/Midplane id from a XYZ coord input -R 101 where X=1 Y=1 Z=1 with no leading 'R'.

load <bluegene.conf file>

Load an already existent bluegene.conf file. This will verify and mapout a bluegene.conf file. After loaded the configuration may be edited and saved as a new file.

create <size> <options>

Submit request for partition creation. The size may be specified either as a count of base partitions or specific dimensions in the X, Y and Z directions separated by "x", for example "2x3x4". A variety of options may be specified. Valid options are listed below. Note that the option and their values are case insensitive (e.g. "MESH" and "mesh" are equivalent).

Start = XxYxZ

Identify where to start the partition. This is primarily for testing purposes. For convenience one can only put the X coord or XxY will also work. The default value is 0x0x0.

Connection = MESH | TORUS | SMALL

Identify how the nodes should be connected in network. The default value is TORUS.

Small: Equivalent to "Connection=Small". If a small connection is specified the base partition chosen will create smaller partitions based on options 32CNBlocks and 128CNBlocks respectively for a Bluegene L system. 16CNBlocks, 64CNBlocks, and 256CNBlocks are also available for Bluegene P systems. Keep in mind you must have enough ionodes to make all these configurations possible.
These number will be altered to take up the entire base partition. Size does not need to be specified with a small request, we will always default to 1 base partition for allocation.
Mesh: Equivalent to "Connection=Mesh".
Torus: Equivalent to "Connection=Torus".

Rotation = TRUE | FALSE

Specifies that the geometry specified in the size parameter may be rotated in space (e.g. the Y and Z dimensions may be switched). The default value is FALSE.

Rotate

Equivalent to "Rotation=true".

Elongation = TRUE | FALSE

If TRUE, permit the geometry specified in the size parameter to be altered as needed to fit available resources. For example, an allocation of "4x2x1" might be used to satisfy a size specification of "2x2x2". The default value is FALSE.

Elongate

Equivalent to "Elongation=true".

copy <id> <count>

Submit request for partition to be copied. You may copy a specific partition by specifying its id, by default the last configured partition is copied. You may also specify a number of copies to be made. By default, one copy is made.

delete <id>

Delete the specified block.

down <node_range>

Down a specific node or range of nodes. i.e. 000, 000-111 [000x111]

up <node_range>

Bring a specific node or range of nodes up. i.e. 000, 000-111 [000x111]

alldown

Set all nodes to down state.

allup

Set all nodes to up state.

save <file_name>

Save the current configuration to a file. If no file_name is specified, the configuration is written to a file named "bluegene.conf" in the current working directory.

clear

Clear all partitions created.

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" or is scheduled to be rebooted.
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".
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: Job is awaiting resource allocation.
PR PREEMPTED: Job terminated due to preemption.
R RUNNING: Job currently has an allocation.
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.
