Is Fortran Still Relevant? Comparing Fortran with Java and C++

A Standard Java Array Package for Technical Computing

Java is almost universally recognized as a good object-oriented language for writing portable programs. However, it still lags behind Fortran and C in performance, particularly for computationally intensive numerical programs. In this paper we present a true multidimensional Array package, and related compiler support, that can bring Fortran-like performance to Java numerical codes. We discuss ...

Mixed-language high-performance computing for plasma simulations

Java is receiving increasing attention as the most popular platform for distributed computing. However, programmers are still reluctant to embrace Java as a tool for writing scientific and engineering applications due to its still noticeable performance drawbacks compared with other programming languages such as Fortran or C. In this paper, we present a hybrid Java/Fortran implementation of a p...

A Comparative Study of Fortran With C++ and Java Using an Object-Oriented Ray Tracing Application

A prototype Fortran-to-Java converter

This is a report on a prototype of a FORTRAN 77 to Java converter, f2j. Translation issues are identi ed, approaches are presented, a URL is provided for interested readers to download the package, and some unsolved problems are brought up. F2j allows value added to some of the investment on FORTRAN code, in particular, those well established FORTRAN libraries for scienti c and engineering comp...
