MATLAB Parallel Computing: Some Announcements
ITHACA is an IBM iDataPlex cluster recently installed by Virginia Tech’s Advanced Research Computing facility. It is intended to gradually take over the high performance computing load from System X. ITHACA supports OpenMP, MPI and Parallel MATLAB programming. Right Now: Friendly users accepted for Ithaca (talk to John Burkardt if you are interested,); Mid October: Ithaca opened to general users (accounts given out through online application.).

MATLAB Parallel Computing: Things Change

“Why There Isn’t Parallel MATLAB”
”There actually have been a few experimental versions of MATLAB for parallel computers... We have learned enough from these experiences to make us skeptical about the viability of a fully functional MATLAB running on today’s parallel machines.” Cleve Moler, 1995.

Introduction: MATLAB

MATLAB is a computing environment that is halfway between a programming language (where a user must do everything) and a menu-driven application (where the user only makes high level decisions). Users always have the ability to lay out the precise details of an algorithm themselves. They rely on MATLAB commands to access intelligent, flexible, and optimized versions of standard algorithms.

Introduction: MATLAB Adds Parallelism

The MathWorks has recognized that parallel computing is necessary for scientific computation. The underlying MATLAB core and algorithms are being extended to work with parallelism. An explicit set of commands has been added to allow the user to request parallel execution or to control distributed memory. New protocols and servers allow multiple copies of MATLAB to carry out the user’s requests, to transfer data and to communicate. MATLAB’s parallelism can be enjoyed by novices and exploited by experts.

Introduction: Local Parallelism

MATLAB has developed a Parallel Computing Toolbox which is required for all parallel applications. The Toolbox allows a user to run a job in parallel on a desktop machine, using up to 8 ”workers” (additional copies of MATLAB) to assist the main copy. If the desktop machine has multiple processors, the workers will activate them, and...
