• Node: A single machine in a supercomputer. This will be either a physical machine or a virtual machine. 

• Scheduler:  The application on our end that assigns compute resources for jobs.

• Slurm: The brand name of our scheduler which manages and allocates resources.

• MPI: Message Passing Interface (MPI) is a standardized and portable function used on parallel computing architecturesSBATCH: This is a means of submitting a batch job, from which tasks will be executed, to execute on allocated resources.

What is a Job?

A job is any work submitted to the supercomputer that requests or uses its resources. There are three types of jobs that a user can request:

...

This reduced example will still allocate 50 cores with 5 cores per task on any number of available nodes. Note, since there is no MPI capability in the Aloe environment, you will likely always add -N 1. This will ensure that each job’s worker has the lowest latency to each other.
