The Random Walk with Parallel Programming item shows how to use Parallel Region and Parallel Loop Model Elements to simultaneously compute N random walks on a lattice. The simulations show how computational performance depends on the number of threads and how the computational load is distributed among the processor cores.  Random walk trajectories are displayed in a plot window and additional windows display the computational performance of each thread and the time evolution of the average displacement of the random walks.  

The parallel Random Walk simulations were developed using the Easy Java Simulations (EJS) modeling tool and are distributed as a ready-to-run (compiled) jar files.  Users can modify these simulations if they have EJS installed by right-clicking within the plot and selecting "Open Ejs Model" from the pop-up menu item.
