Which of the following is NOT required when submitting a job to an HPC system using SLURM?

Question

BlackTom AI · Accepted Answer

In SLURM-based job submissions, several elements are typically required to describe and control the execution. 
Option 1: Allocating the required number of processing cores. This is a standard requirement because SLURM must know how many CPUs to grant for the job, usually specified with something like --cpus-per-task or -n for tasks. Without this, the scheduler cannot allocate appropriate resources. 
Option 2: Specifying the maximum runtime for the job. This is another common requirement since SLURM uses a time limit (e.g., --time or -t) to manage scheduling and enforce fair usage; without a specified wall-time, the job may be withheld or fail to submit depending on the cluster policy. 
Option 3: Loading all necessary software modules in the job script. While not always mandatory for every single submission, loading the appropriate software modules is typically required to ensure the job runs with the correct environment and dependencies; otherwise the executable may fail due to missing libraries or incompatible versions. 
Option 4: Embedding job instructions directly into the SLURM queue manager without using a separate script. This statement describes an approach that is not standard practice: submitting a job by placing instructions inside the queue manager’s interface instead of via a separate submission script. In SLURM, the usual workflow is to prepare a job script (a batch script) and submit it with sbatch; embedding instructions directly into the queue manager is not the typical or recommended method. Therefore, this option is not required and, in fact, not how SLURM submissions are normally performed. 
Overall, the items in Options 1–3 reflect common submission requirements or best practices, while Option 4 describes an approach that is not standard and is not required for SLURM submissions.
