 ==== Example of a very basic job script ====
-Consider the following example of a very basic job script named ''job1.sh'':

-Now just submit your job script using ''sbatch job1.sh'' from the command line. Please try to run jobs directly from the /scratch///username// cluster wide filesystem to lower the load on the /home server. For testing purposes set the runtime of your job below 1 minute and submit it to the test partition by adding ''-p test'' to sbatch:
+Please note that your job will be killed by the queueing system if it tries to use more memory than requested or if it runs longer than the time specified in the batch script. So to be on the safe side you can set these values a litte bit higher. If you set the values to high, your job might not start because there are not enough resources (e.g. no machine has that amount of memory you are asking for).
