In this paper, an object-oriented design for beam dynamics simulations in accelerators is implemented using Fortran language. Using module and derived type in F90, we can emulate object concept in the object-oriented design. This gives Fortran code a better maintainability, reusability, and extensibility. The overhead associated with the objectoriented implementation has only a minor effect on ...

This manual describes version 1.6 of the programming language hepawk, designed for convenient scanning of data structures arising in the simulation of high energy physics events. The interpreter for this language has been implemented in FORTRAN-77, therefore hepawk runs on any machine with a FORTRAN-77 compiler. e-mail: [email protected]

The program MadGraph is presented which automatically generates postscript Feynman diagrams and Fortran code to calculate arbitrary tree level helicity amplitudes by calling HELAS[1] subroutines. The program is written in Fortran and is available in Unix and VMS versions. MadGraph currently includes standard model interactions of QCD and QFD, but is easily modi ed to include additional models s...

SVM-Fortran is a language designed t o program highly parallel systems with a global address space. A compiler for SVM-Fortran is described which generates code for parallel machines; our current target machine is the Intel Paragon X P / S with an SVMextension called ASVM. Performance numbers are given for applications and compared to results obtained with corresponding HPFversions.

Geobrowser tools offer easy access to geographical and map images over which geospatial data can be overlaid, a process that provides a powerful new visualization resource for scientists. Many of these tools make use of the well-documented KML/XML data formats, and the challenge for the scientist is to generate KML files from their simulation and analysis programs. Since many of these programs ...

High Performance Fortran is an informal standard for extensions to Fortran 90 to assist its implementation on parallel architectures, particularly for data-parallel computation. Among other things, it includes directives for expressing data distribution across multiple memories, and concurrent execution features. This paper provides an informal introduction to the main features of HPF.

This article describes the way to use pthreads library in Fortran programs. With most of the modern day processors having more and more built in capability of parallelism, there is ample need of utilizing this power at the application level, especially in scientific applications which involves lots of number crunching and multi GB disk handling. To utilize the power of multi threading for scien...

A basic problem in programming for parallel architectures is that each machine has its own design, and also its own specific software for accessing its hardware features. In 1992, as a response to this situation, the High Performance Fortran Forum (HPFF) was founded, under the guidance of Professor Ken Kennedy, to produce a portable Fortran-based interface to parallel machines for the solution ...

Fortran D is a version of Fortran extended with data decomposition speciications. It is designed to provide a machine-independent programming model for data-parallel applications and has heavily innuenced the design of High Performance Fortran (HPF). In previous work we described Fortran D compilation algorithms for individual procedures. This paper presents an interprocedural approach to analy...

In this paper we describe an algorithm and a Fortran 90 module (Conical) for the computation of the conical function P −1 2+iτ (x) for x > −1, m ≥ 0, τ > 0. These functions appear in the solution of Dirichlet problems for domains bounded by cones; because of this, they are involved in a large number of applications in Engineering and Physics. In the Fortran 90 module, the admissible parameter r...
