Parallel programming is widely acknowledged to be more diicult than sequential programming. One reason for this is that parallel programming systems are more diicult to use than their sequential counterparts. In particular, few parallel programming systems can support the software engineering requirements of large applications. We intend to assess and compare the usability of a variety of paral...

We present a new experimental framework, the F-PRAM model, for modeling and studying the effects of different properties of parallel machines. The goal of the new model is to provide programmer-level facilities for more accurate and portable computation-communication balancing. As a computation model, F-PRAM provides shared memory but guides the usage of the shared memory by a set of parameters...

Motivated by biological inspiration and the issue of code disruption, we develop a new form of LGP called Parallel LGP (PLGP). PLGP programs consists of n lists of instructions. These lists are executed in parallel, after which the resulting vectors are combined to produce program output. PGLP limits the disruptive effects of crossover and mutation, which allows PLGP to significantly outperform...

The ParaScope project is developing an integrated collection of tools to help scientiic programmers implement correct and eecient parallel programs. The centerpiece of this collection is the ParaScope Editor, an intelligent interactive editor for parallel Fortran programs. The ParaScope Editor reveals to users potential hazards of a proposed parallelization in a program. It also provides a vari...

The aim of this dissertation was to demonstrate that using visual parallel programming languages can provide natural and intuitive representations of the parallel applications in order to assist programmers and make parallel programming more accessible. The approach taken was to define a new visual parallel programming language, called Vidim, based on the partitioned global address space (PGAS)...

MatlabMPI is a Matlab implementation of the Message Passing Interface (MPI) standard and allows any Matlab program to exploit multiple processors. MatlabMPI currently implements the basic six functions that are the core of the MPI point-to-point communications standard. The key technical innovation of MatlabMPI is that it implements the widely used MPI " look and feel " on top of standard Matla...

In this workshop session, three speakers present their viewpoints and contributions to the topic of portable parallel programming languages. They are Dennis Gannon from In-diana University, David Loveman from Digital Equipment Corporation, and David Padua from the University of Illinois. Their presentations discuss extensions to C ++ , Fortran, and compiler support for standard languages on par...
