Parallel Computing

Mathematica has the ability to execute computations on a set of workers in parallel. These workers can run on the local workstation and/or on a set of workstations.

Official documentation is provided at http://reference.wolfram.com/mathematica/guide/ParallelComputing.html.

Simple examples are provided at http://reference.wolfram.com/mathematica/ParallelTools/tutorial/ParallelEvaluation.html.

Setup

By default Mathematica starts workers only on the local workstation. To enable workers on more than one machine follow these instructions:

• Start Mathematica and open the Preferences window via Edit->Preferences....
• Open the tab Parallel.
• Open the subtab Lightweight Grid.
• Click on Enable Lightweight Grid.
• A list with computers should appear and be filled automatically within a few seconds. (see screenshot)
• Adjust the number of kernels to run on each node by using the + and - buttons in the computer list.

To verify the configuration click on Parallel Kernel Status.... The window Parallel Kernel Status should open and the kernels on the specified computers should be launched automatically. (see screenshot)
