For the commands that do use Spark, you can request multiple CPUs. NOTE: Please provide the exact number of CPUs to the spark command. For example if you requested 10 CPUs, use --spark-master local[10] instead of --spark-master local[*]. If you want to use multiple nodes to scale the Spark cluster, you have to first deploy a SPARK cluster and then set the appropriate variables in the GATK command.
