Slurm Workload Manager - Job State Codes

# Job State Codes

Each job in the Slurm system has a state assigned to it. How the job state is displayed depends on the method used to identify the state.

## Overview

In the Slurm code, there are base states and state flags. Each job has a base state and may have additional state flags set. When using the REST API, both the base state and current flag(s) will be returned.

When the squeue and sacct command report a job state, they represent it as a single state. Both will recognize all base states but not all state flags. If a recognized flag is present, it will be reported instead of the base state. Refer to the relevant command documentation for details.

This page represents all job codes and flags that are represented in the code. The names provided are the string representations that are used in user-facing output. For most, the names used in the code are identical, with `JOB_` at the start. For more visibility into the job states and flags, set `DebugFlags=TraceJobs` and `SlurmctldDebug=verbose` (or higher) in slurm.conf.

## Job states

Each job known to the system will have one of the following states:

Name | Description
`BOOT_FAIL` | terminated due to node boot failure
`CANCELLED` | cancelled by user or administrator
`COMPLETED` | completed execution successfully; finished with an exit code of zero on all nodes
`DEADLINE` | terminated due to reaching the latest acceptable start time specified for the job
`FAILED` | completed execution unsuccessfully; non-zero exit code or other failure condition
`NODE_FAIL` | terminated due to node failure
`OUT_OF_MEMORY` | experienced out of memory error
`PENDING` | queued and waiting for initiation; will typically have a reason code specifying why it has not yet started
`PREEMPTED` | terminated due to preemption; may transition to another state based on the configured PreemptMode and job characteristics
`RUNNING` | allocated resources and executing
`SUSPENDED` | allocated resources but execution suspended, such as from preemption or a direct request from an authorized user
`TIMEOUT` | terminated due to reaching the time limit, such as those configured in slurm.conf or specified for the individual job

## Job flags

Jobs may have additional flags set:

Name | Description
`COMPLETING` | job has finished or been cancelled and is performing cleanup tasks, including the epilog script if present
`CONFIGURING` | job has been allocated nodes and is waiting for them to boot or reboot
`LAUNCH_FAILED` | failed to launch on the chosen node(s); includes prolog failure and other failure conditions
`POWER_UP_NODE` | job has been allocated powered down nodes and is waiting for them to boot
`RECONFIG_FAIL` | node configuration for job failed
`REQUEUED` | job is being requeued, such as from preemption or a direct request from an authorized user
`REQUEUE_FED` | requeued due to conditions of its sibling job in a federated setup
`REQUEUE_HOLD` | same as `REQUEUED` but will not be considered for scheduling until it is released
`RESIZING` | the size of the job is changing; prevents conflicting job changes from taking place
`RESV_DEL_HOLD` | held due to deleted reservation
`REVOKED` | revoked due to conditions of its sibling job in a federated setup
`SIGNALING` | outgoing signal to job is pending
`SPECIAL_EXIT` | same as `REQUEUE_HOLD` but used to identify a special situation that applies to this job
`STAGE_OUT` | staging out data (burst buffer)
`STOPPED` | received SIGSTOP to suspend the job without releasing resources
`UPDATE_DB` | sending an update about the job to the database
