Created page with "Each partition (or “pool”) now has several QoS tiers that determine job priority and preemption behavior. {| class="wikitable" |+ QOS types for each pool |- ! QOS !! Purp..."

New page

Each partition (or “pool”) now has several QoS tiers that determine job priority and preemption behavior.

{| class="wikitable"
|+ QOS types for each pool
|-
! QOS !! Purpose !! Preempts !! Can be preempted by
|-
| Share-type QoS (e.g. 0.125_48c_8g, 0.75_48c_8g) || For multi-owner pools; defines each owner’s guaranteed slice (CPU/GPU portion). || owner,public || --
|-
| owner|| Used on your lab’s pool to run above your guaranteed slice (higher than public). || public || share-type QoS
|-
| public (partition: power-general-shared-pool) || Used on cluster-wide shared pools for friendly or opportunistic runs || -- || owner, share-type QoS
|-
| public (partition: power-general-public-pool) || Used on cluster-wide shared, little group of nodes, not preemptable || -- || --
|}

Preemption rule summary:
share-type QoS > owner > public

This means:

• A share-type QoS job can preempt owner or public jobs on the same pool.

• An owner job can preempt public jobs.

• Public jobs cannot preempt any other jobs.

==How to Submit Jobs with the Correct QoS==
Below are examples of how to use the new QoS tiers with your account:
'''Owner QoS (on your lab’s pool)'''
<pre>
sbatch -A UIDHERE-users_v2 -p UIDHERE-pool --qos=owner --time=02:00:00 run.sh
</pre>
'''Share-type QoS (on a multi-owner pool, for your guaranteed slice)'''
<pre>
sbatch -A UIDHERE-users_v2 -p gpu-dudu-tzach-yoav-pool --qos=0.125_48c_8g --gres=gpu:A100:1 run.sh
</pre>
'''Public QoS (friendly, cluster-wide)'''
<pre>
sbatch -A UIDHERE-users_v2 -p power-general-shared-pool --qos=public --time=01:00:00 run.sh
</pre>
'''For the small, protected CPU pool'''
<pre>
sbatch -A UIDHERE-users_v2 -p power-general-public-pool --qos=public --time=01:00:00 run.sh
</pre>
===Handy Checks During Usage===
You can monitor your jobs and see their QoS and reasons:
<pre>
squeue --me -O "JOBID,ACCOUNT,PARTITION,QOS,STATE,REASON"
sprio -w
</pre>
If your job was preempted, check:
<pre>
sacct -j <jobid> --format=JobID,State,Reason
</pre>
