Job status

  • In order to see your jobs only, and no others, run
    $ squeue -u <username>

Interactive running

  • Using salloc, you get an interactive shell to run your jobs in, when your nodes are allocated. This works like an interactive shell (-I) does in PBS - including the fact that you cannot use the window while you wait for - perhaps - a long time before the job starts.

SLURM commands and information

SLURM commands and information

There are many more commands than the ones we have chosen to look at below, but they are the most commonly used ones. You can find more information on the SLURM homepage: SLURM documentation

You can run programs either by giving all the commands on the command line or by submitting a job script. If you ask for the resources on the command line, you will wait for the program to run before you can use the window again (unless you can send it to the background with &).

Batch systems

The Batch system

Once a parallel program has been successfully compiled it can be run on multi-processor/multi-core computing nodes directly or, in production environment, by means of a batch system. Batch systems keeps track of available system resources and takes care of scheduling jobs of multiple users running their tasks simultaneously. It typically organizes submitted jobs into some sort of prioritized queue. The batch system is also used to enforce local system resource usage and job scheduling policies.



This section provides information about the compilers at HPC2N. There are instructions about their usage, and some of the most popular flags, as well as the provided libraries and how to link to them.

There is also a section with an introduction to makefiles, a few examples, and links to more information.
