A configuration approach to parallel programming

This paper advocates a configuration approach to parallel programming for distributed memory multicomputers, in particular, arrays of transputers. The configuration approach prescribes the rigorous separation of the logical structure of a program from its component parts. In the context of parallel programs, components are processes which communicate by exchanging messages. The configuration defines the instances of these processes which exist in the program and the paths by which they are interconnected.

The approach is demonstrated by a toolset (Tonic) which embodies the configuration paradigm. A separate configuration language is used to describe both the logical structure of the parallel program and the physical structure of the target multicomputer. Different logical to physical mappings can be obtained by applying different physical configurations to the same logical configuration. The toolset has been developed from the Conic system for distributed programming. The use of the toolset is illustrated through its application to the development of a parallel program to compute Mandelbrot sets.     

An experiment for truly parallel logic programming

A truly parallel logic programming system is proposed. The system is based on the commercially available parallel logic programming language STRAND, which has been extended in order to overcome the inherent limitations of such systems, like AND-type of parallelism, lack of backtracking, limited unification, etc. The system has been tested using an example from the area of natural language processing.     

Computational science in high schools: defining curricula and environments

The paper presents a new approach for the introduction of computational science into high level school curricula. It also discusses a set of real life problems that are appropriate for these curricula because they can be described through simple models. The computer based simulation of these systems require an ad hoc environment, including a programming language, suitable for this target age. The paper proposes a new environment, the ORESPICS environment, including a new programming language. The sequential part of the language integrates the classical imperative constructs with a simple set of graphical primitives, mostly taken from the LOGO language. The concurrent part of the language is based on the message passing paradigm. The solutions of some classical problems through ORESPICS are shown.

2DT-FP: A parallel functional programming language on two-dimensional data

We propose a new paradigm for programming multiprocessor systems, 2DT (two-dimensional transformations). 2DT programs are composed of local computations on linear data (columns) and global transformations on 2-dimensional combinations of columns (2D-arrays). Local computations can be expressed in a functional or imperative base language; a typed variant of Backus' FP is chosen for 2DT-FP. The level of abstraction of 2DT makes it suitable for programming a relevant set of algorithms, in general any algorithms, whose data can be easily mapped to 2-dimensional representations. A set of examples tries to prove this claim. An interleaving semantics for 2DT-FP is given, exposing the potential for parallel execution of 2DT-FP programs. The claim is proved that any sequential and thus any parallel execution will deliver the same result. The implementation realized on the Intel Hypercube is described.

: A heterogeneous environment for HPC applications

Technological directions for innovative HPC software environments are discussed in this paper. We focus on industrial user requirements of heterogeneous multidisciplinary applications, performance portability, rapid prototyping and software reuse, integration and interoperability of standard tools. The various issues are demonstrated with reference to the PQE2000project and its programming environment Skeleton-based Integrated Environment (). includes a coordination language, , allowing the designers to express, in a primitive and structured way, efficient combinations of data parallelism and task parallelism. The goal is achieving fast development and good efficiency for applications in different areas. Modules developed with standard languages and tools are encapsulated into structures to form the global application. Performance models associated to the coordination language allow powerful optimizations to be introduced both at run time and at compile time without the direct intervention of the programmer. The paper also discusses the features of the environment related to debugging, performance analysis tools, visualization and graphical user interface. A discussion of the results achieved in some applications developed using the environment concludes the paper.     

Uses of the SIMULA process concept

The class concept of the SIMULA programming language is well known as the father of the concept of abstract data types. A SIMULA class can however also act as a process. This paper illustrates by some examples for existing programs how the process aspect of the class concept can be used to structure programs in neat ways. All the examples are taken from real production programs in heavy usage today, but the examples have been simplified in this paper to illustrate the main ideas.
