Slurm Job Status Reference Sheet

Below is a reference sheet for slurm job statuses, their meaning, and common causes.

Code	Status	Description	Common Cause or Example
PD	Pending	The job is awaiting resource allocation and has not yet started execution.	Waiting for resources, partition limits, or job dependencies.
R	Running	The job currently has an allocation and is actively executing on the assigned nodes.	Job is actively running code or computations.
CD	Completed	The job has successfully terminated all processes on all allocated nodes and completed its execution.	Normal completion — program exited cleanly with code 0.
F	Failed	The job terminated with a non-zero exit code or encountered another failure condition during execution.	Script error, segmentation fault, or crash.
CG	Completing	The job is in the process of completing, but some processes on some nodes may still be active.	Cleanup in progress after job termination.
CA	Cancelled	The job was explicitly cancelled by the user or a system administrator.	User ran scancel <jobid> or dependency job failed.
CF	Configuring	The job has been allocated resources, but is waiting for them to become ready for use (e.g., booting up).	Nodes are powering on or network initialization is pending.
S	Suspended	The job has an allocation, but its execution has been temporarily suspended.	Admin intervention, system load balancing, or checkpoint/restart testing.
ST	Stopped	The job has been stopped, but its cores are retained, unlike a suspended job which releases its cores.	Manually paused for debugging or maintenance.
TO	Timeout	The job reached its allocated time limit and was terminated.	Walltime (#SBATCH -t) exceeded before job finished.
OOM	Out of Memory	The job terminated due to an out-of-memory error.	Process exceeded node memory; increase --mem or optimize code.
NF	Node Fail	The job terminated due to the failure of one or more allocated nodes.	Hardware failure, network outage, or node reboot.
PR	Preempted	The job was terminated by another job, typically due to a higher priority or resource requirement.	Higher-priority user or system reservation took precedence.
