Emerging GPU architectures for high performance computing are well suited to a data-parallel programming model. This paper presents preliminary work examining a programming methodology that provides Fortran programmers with access to these emerging systems. We use array constructs in Fortran to show how this infrequently exploited, standardized language feature is easily transformed to lower-le...

ABSTRACT REC (Regular Expression Compiler) is a concise programming language development in mayor Mexican Universities at end of 60’s which allows students to write programs without knowledge of the complicated syntax of languages like FORTRAN and ALGOL. The language is recursive and contains only four elements for control. This paper describes use of the interpreter of REC written in FORTRAN o...

This is a useful definition of HPC – since it reflects the reality that HPC is a moving target: what is state of the art supercomputing this year will be desktop computing in a few years' time. Before we look towards the future for HPC, it is well worthwhile for us to spend a little time surveying the incredible technological progress in computing over the past 50 years. We will then quickly re...

In this paper we tackle the problem of connecting low-level Fortran programs to high-level Python programs. The difficulties of mixed language programming between Fortran and C are resolved in an almost compiler and platform independent way. We provide a polished software tool F2PY that can (semi-)automatically build interfaces between the Python and Fortran languages and hence almost completel...

In the past decade, the programming languages C++, FORTRAN 90 and Oberon-2 allevolved from their ancestors. This invites to reflect upon the suitability ofthese modern programming languages for scientific and engineering computing. Inthe first part, we compare their primary language features, as needed byscientists and engineers. In the second part, we list some useful featuresmissing in Oberon...

A_ In this paper I discuss the issues surrounding the comparison and selection of a programming language to be used in high energy physics software applications. The evaluation method used was specifically devised to address the issues of particular importance to HEP applications, not just the technical features of the languages considered. The method assumes a knowledge of the requirements of ...

We describe the design and implementation of a program generator that can produce extensions of Fortran that are specialized to support the programming of particular applications. Extensions are specified through parameter structures that can be referred to in Fortran programs to specify the dependency of program parts on these parameters. By providing parameter values, a parameterized Fortran ...

The construction of parallel solutions for numerical problems relates diierent types of languages, for example, speciication languages, programming languages and reasoning languages. Each language has a diierent mechanism for expressing its semantics. An extension of a new speciication language, namely TLA + Lam91b], 1 is introduced, which will be used to specify and develop parallel solutions ...
