 ## Running Parallel Matlab Using Distributed Computing Toolbox / Engine
 
 Recommended parallel mode for running parallel Matlab on Anselm is MPIEXEC mode. In this mode user allocates resources through PBS prior to starting Matlab. Once resources are granted the main Matlab instance is started on the first compute node assigned to job by PBS and workers are started on all remaining nodes. User can use both interactive and non-interactive PBS sessions. This mode guarantees that the data processing is not performed on login nodes, but all processing is on compute nodes.
