Parallel Computing Toolbox Perform parallel computations on multicore computers, GPUs, and computer clusters Parallel Computing Toolbox™ lets you solve computationally and data-intensive problems using multicore processors, GPUs, and computer clusters. High-level constructs—parallel for-loops, special array types, and parallelized numerical algorithms—let you parallelize MATLAB® applications without CUDA or MPI programming. You can use the toolbox with Simulink® to run multiple simulations of a model in parallel. The toolbox provides twelve workers (MATLAB computational engines) to execute applications locally on a multicore desktop. Without changing the code, you can run the same application on a computer cluster or a grid computing service (using MATLAB Distributed Computing Server™). You can run parallel applications interactively or in batch. Built-in Parallel Computing Support in MathWorks Products Key Features ▪ Parallel for-loops (parfor) for running task-parallel algorithms on multiple processors ▪ Support for CUDA-enabled NVIDIA GPUs ▪ Ability to run twelve workers locally on a multicore desktop ▪ Computer cluster and grid support (with MATLAB Distributed Computing Server) ▪ Interactive and batch execution of parallel applications ▪ Distributed arrays and single program multiple data (spmd) construct for large dataset handling and data-parallel algorithms

Implementing Data-Parallel Applications using the Toolbox and MATLAB Distributed Computing Server Distributed arrays in Parallel Computing Toolbox are special arrays that hold several times the amount of data that your desktop computer's memory (RAM) can hold. Distributed arrays apportion the data across several MATLAB worker processes running on a computer cluster (using MATLAB Distributed Computing Server). As a result, with distributed arrays you can overcome the memory limits of your desktop computer and solve problems that require manipulating very large matrices. With over 150...

Running applications interactively is suitable when execution time is relatively short. When your applications need to run for a long time, you can use the toolbox to set them up to run as batch jobs. This enables you to free your MATLAB session for other activities while you execute large MATLAB and Simulink applications. While your application executes in batch, you can shut down your MATLAB session and retrieve results later. The toolbox provides several mechanisms to manage offline execution of parallel programs, such as the batch function and j ob and task objects. Both the batch...
