After years of being dismissed as too slow for scientiic computing , C++ has caught up with Fortran and appears ready to give it stii competition. We survey the reasons for the historically poor performance of C++ (pairwise expression evaluation, the abstraction penalty, aliasing ambiguities) and explain how these problems have been resolved. C++ can be faster than Fortran for some applications...

In their current Fortran product CF77TM, Cray Research, Inc. has defined a Fortran based programming model for the Cray T3DTM system that allows programmers to specify both data sharing and work sharing. Analysis of this programming model identifies key language features to be retained and others that should be eliminated. Because future Fortran programming directions are based on CF90TM, this ...

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...

This paper briefly introduces SaC: a data-parallel language with an imperative feel but side-effect free and declarative. The experiences of porting a simulation of unsteady shock waves in the Euler system from Fortran to SaC are reported. Both the SaC and Fortran code was run on a 16-core AMD machine. We demonstrate scalability and performance of our approach by comparison to Fortran.

This paper reports on the status of the Fortran translator for the Cedar computer at the end of March, 1991. A brief description of the Cedar Fortran language is followed by a discussion of the fortran77 to Cedar Fortran parallelizer that describes the techniques currently being implemented. A collection of experiments illustrate the e ectiveness of the current implementation, and point toward ...

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...
