Job Templates

Here you can find example job script templates for a variety of job types

  1. Single-threaded tasks
  2. Array jobs
  3. Multi-threaded tasks
  4. MPI tasks
  5. Hybrid MPI/OpenMP tasks
  6. GPU tasks
  7. MPI+GPU tasks

You can copy and paste the examples to use as a base - don't forget to edit the account and e-mail address!

Single threaded tasks

Here we want to use a tool that cannot make use of more than one CPU at a time.

The important things to know are:

  • How long do I expect the job to run for?
  • How much memory do I think I need?
  • Do I want e-mail notifications?
  • What modules (or other software) do I need to load?
#!/bin/bash

#SBATCH --nodes 1
#SBATCH --ntasks 1
#SBATCH --partition cpu
#SBATCH --mem 8G
#SBATCH --time 12:00:00

#SBATCH --mail-type END,FAIL 
#SBATCH --mail-user ursula.lambda@unil.ch

module purge
module load gcc r

Rscript myrcode.R

Array jobs

Here we want to run an array job where there are N almost identical jobs that differ only in the input parameters.

See our introductory course for more details

The important things to know are:

  • How long do I expect each individual job to run for?
  • How much memory do I think I need per individual job?
  • How many array elements do I have?
  • How am I going to prepare my inputs for the elements?
  • Do I want e-mail notifications?
  • What modules (or other software) do I need to load?
