==Submitting Jobs==
=== Resource Scheduler ===
[[Slurm]] 20.11.9 is used for job scheduling.

There are '''2''' main ways to request resources:

* '''Interactive:''' Use <code>srun</code> for jobs where you need direct interaction with the running task, often after using `salloc` for interactive sessions.
* '''Batch:''' Use <code>sbatch</code> for jobs that can run without user interaction, typically for longer or resource-intensive tasks, submitting them to the Slurm queue for scheduled execution.
Here's an overview of our main partitions:

* '''debug'''
<pre>
Purpose: Quick, short jobs for testing and debugging.
      Max Time: 12 hours
  Default Time: 1 hour
      Max GPUs: 2
      Max CPUs: 64
           QoS: debug_qos
   Limitations: No array jobs
</pre>

* '''general'''
<pre>
Purpose: General, standard computing tasks.
      Max Time: 2 days
  Default Time: 6 hours
      Max GPUs: 8
      Max CPUs: 128
           QoS: normal
   Limitations: No interactive sessions | sbatch only
</pre>

* '''preempt'''
<pre>
Purpose: Long-running jobs that can be preempted for higher priority tasks.
      Max Time: 31 days
  Default Time: 3 hours
      Max GPUs: 24
      Max CPUs: 256
           QoS: preempt_qos
   Limitations: No interactive sessions | sbatch only
</pre>

* '''cpu'''
<pre>
Purpose: CPU-only computing tasks.
      Max Time: 2 days
  Default Time: 6 hours
      Max GPUs: 0
      Max CPUs: 128
           QoS: cpu_qos
   Limitations: No interactive sessions | sbatch only
</pre>

* '''array'''
<pre>
Purpose: Array jobs for parallel task execution.
      Max Time: 12 days
  Default Time: 6 hours
      Max GPUs: 8
      Max CPUs: 256
           QoS: array_qos
   Limitations: No interactive sessions | sbatch only
</pre>

=== Viewing Partition Details ===

To explore the full configuration of all partitions, use the <code>scontrol</code> command:

* <code>scontrol show part</code>: Displays detailed information about all available partitions.

For specifics on a particular partition, include its name:

* <code>scontrol show part <partition_name></code>: Shows detailed settings for the specified partition (e.g., <code>scontrol show part debug</code>).

For detailed information on how to use these partitions, see our documentation [[Slurm|here]].

=== Viewing QoS Details ===
Each partition is associated with a specific QoS (e.g., <code>debug_qos</code>, <code>normal</code>, <code>preempt_qos</code>), which defines rules such as maximum resource usage and preemption behavior.

To view QoS information associated with your user account:
  
  sacctmgr show user $USER withassoc format=User,Account,DefaultQOS,QOS%4
