The JLAPACK project provides the LAPACK numerical subroutines translated from their subset FORTRAN 77 source into class files, executable by the Java Virtual Machine (JVM) and suitable for use by Java programmers. This makes it possible for Java applications or applets, distributed on the World Wide Web (WWW) to use established legacy numerical code that was originally written in FORTRAN. The t...

LAPACK3E is a version of the public domain numerical linear algebra package LAPACK 3 enhanced with selected features of Fortran 90. The use of Fortran 90 enhances LAPACK by allowing a common source for single and double precision, more uniform specification of scaling constants, and encapsulation of some internal subroutine interfaces. Thread-safety is introduced as a new feature for LAPACK by ...

Fortran 90 is the actual standard in term of data parallel language for scientiic computing. To develop a data parallel algorithm on a distributed memory machine, programmers generally use the High Performance Fortran extension of Fortran 90, in particular the data mapping directives. HPF-Builder8] graphical environment goal is to free the HPF programmers of all the syntactic constraints due to...

MPI is a de facto standard for portable parallel programming using a message passing paradigm. Interest is growing in other paradigms, in particular Partitioned Global Address Space (PGAS) languages such as Coarray Fortran, UPC and Titanium. Most Computational Science and Engineering codes are written in Fortran, and the 2008 Fortran standard will include coarrays, a Cray initiated PGAS extensi...

This paper discusses the concept, application, and usefulness of software design patterns for scientific programming in Fortran 90/95. An example from the discipline of object-oriented design patterns, that of a game based on navigation through a maze, is used to describe how some important patterns can be implemented in Fortran 90/95 and how the progressive introduction of design patterns can ...

Bouclettes is a source to source loop nest parallelizer. It takes as an input Fortran uniform, perfectly nested loops and gives as an output an equivalent High Performance Fortran program with data distribution directives and parallel ($HPF! INDEPENDENT) loops. This paper explains how the HPF program is built from a “shifted linear schedule” and a data allocation. We focus on the problems we ha...

In this paper we will give a short introduction to the installation and efficiency of state-of-the-art direct solver packages like CROUT and UMFPACK for linear systems, combined with highly processor optimised BLAS libraries. We will give an overview about the methods that can be used to integrate these libraries into Fortran programs compiled with the Compaq® Visual Fortran or the Intel® Fortr...

A collaborative software development approach is described. The software product is an adaptation of proven computational capabilities combined with new capabilities to form the Agency’s next generation aerothermodynamic and aerodynamic analysis and design tools. To efficiently produce a cohesive, robust, and extensible software suite, the approach uses agile software development techniques; sp...

High-performance scientific applications are usually built from software modules written in multiple programming languages. This raises the issue of language interoperability which involves making calls between languages, converting basic types, and bridging disparate programming models. Babel provides a featurerich, extensible, high-performance solution to the language interoperability problem...
