 This will run 10 different tasks in parallel. Note that this will appear as a single job if you use *squeue* and that you can't separate the outputs in a different file for each task (To do that, you can refer to the [Job array section](Slurm job array)).

+- *"my sbatch option does not seem to be set"*
+  - the *bash* command will not interpret the *#SBATCH* options, make sure to use *sbatch* 
+  - the *sbatch* command will stop to interpret if it encounters anything different from a space, a comment   or a *#SBATCH* option. 
+- *"my tasks are not performed in parallel"*
+  - make sure that you properly set the correct number of task in the options
+  - make sure that you putted the "&" at the end of you command line (in your file)
