+## What Are Accounts?
 
 Users can belong to multiple Slurm accounts and multiple users can belong to a single Slurm account. Slurm accounts typically correspond with a group of users and we generally create them on a project basis. Slurm accounts are used for tracking usage and enforcing resource limits. When new project accounts are created, they will consume a portion of the shares allocated for the parent account, which is typically associated with a broader administrative entity, such as an institution, department, or research group.

+## What QOS Should I Choose for My Job?
 
 QoS (Quality of Service) define job with different priorities and resource limits. Selecting the appropriate QoS can influence your job’s priority in the queue. Be mindful of the tradeoff that comes with a higher QOS: while higher QoS levels allow longer runtimes, they may result in longer wait times due to lower scheduling priority.

 For long jobs, select the **long QoS**, which allows for extended runtimes but may have lower scheduling priority. It’s advisable to implement **checkpointing** in your application if possible. Checkpointing allows your job to save progress at intervals, so you can resume from the last checkpoint in case of interruptions, mitigating the risk of resource wastage due to unexpected failures.

 1. **Shorten the time limit** on your job, if possible. This may allow the scheduler to fit your job into a time window while it is trying to make room for a larger job (using Slurm's **backfill functionality**).
