Nodes, Tasks and CPU's per task

In Slurm terminology, a task is an instance of a running a program.

If your program supports communication across computers or you plan on running independent tasks in parallel, request multiple tasks with the following command. The default value is set to 1.

--ntasks=<number>

For more advanced programs, you can request, multiple nodes, multiple tasks and multiple CPUs per task and/or per nodes.

If you need multiple nodes, then you can define the number of nodes like this

 --nodes=<number>
