Editorial: Portable software tools for parallel architectures

Portable Tools for Interoperable Grids Modular Architectures and Software for Job and Workflow Management

The emergence of Grid computing infrastructures enables researchers to share resources and collaborate in more efficient ways than before, despite belonging to different organizations and being geographically distributed. While the Grid computing paradigm offers new opportunities, it also gives rise to new difficulties. This thesis investigates methods, architectures, and algorithms for a range...

PRELUDE: A System for Portable Parallel Software

In this paper we describe Prelude, a programming language and accompanying system support for writing portable MIMD parallel programs. Prelude supports a methodology for designing and organizing parallel programs that makes them easier to tune for particular architectures and to port to new architectures. It builds on earlier work on Emerald, Amber, and various Fortran extensions to allow the p...

A Portable 3D FFT Package for Distributed-Memory Parallel Architectures

1 I n t r o d u c t i o n Multidimensional FF’I’s are used frequently in engineerillg and scientific calculations, especially in image processing. Parallel implementations of FFT generally follow two approaches. One is the binary-exchange approach[l ,2], where data exchanges take place in all pairs of processors with processor numbers differing by one bit. Another one is the transpose approach[...

Tools for Design and Mapping of Portable Parallel Programs

In this paper, we study tools for design and mapping of portable parallel programs. An essential component of such a tool is a mapping algorithm which can map arbitrary program tasks onto arbitrary computer systems. A generic fast recursive mapping algorithm, which is part of the Cluster-M parallel programming tool, is presented. This algorithm is suitable for the task scheduling problem as wel...
