batch execution example OpenMP

At https://doc.zih.tu-dresden.de/jobs_and_resources/slurm/

Into the "Job file OpenMP" example it's written openmpi_application. Although I believe should be openmp_application. I also believe that this information shall be over there: The enviroment variable SLURM_CPUS_PER_TASK Number of cpus requested per task. Only set if the --cpus-per-task option is specified.
