A parallel pool is a set of MATLAB ® workers on a compute cluster or desktop. With default preferences, MATLAB ® starts a pool on the local machine with one worker per physical CPU core, up to the preferred number of workers. Thus, it helps make good and full use of the CPU. I assume such scenarios have lead to the recommendation of at most 1 worker per CPU in clusters. You use functions in the Parallel Computing Toolbox to automatically divide tasks and assign them to these workers to execute the computations in parallel. 7 Parallel Capabilities Task Parallel Data Parallel Environment Built-in support with Simulink, toolboxes, and blocksets matlabpool Local workers parfor distributed array >200 functions Configurations batch MathWorks job manager job/task spmd co-distributed array MPI interface The goal of this paper is to analyze and compare serial algorithm with parallel algorithm using parallel matlab toolbox.
