DKLAG6 is a FORTRAN 77 code widely used to solve delay differential equations (DDEs). Like all the popular Fortran DDE solvers, new users find it formidable and in many respects, it is not easy to use. We have applied our experience writing DDE solvers in Matlab and the capabilities of Fortran 90 to the development of a friendly Fortran DDE solver. How we accomplished this may be of interest to...

We describe a technique and a tool supporting partial evaluation of Fortran programs, i.e. their specialization for specific values of their input variables. We aim at understanding old programs, which have become very complex due to numerous extensions. From a given Fortran program and these values of its input variables, the tool provides a simplified program, which behaves like the initial o...

The GPSS-FORTRAN simulator is a Fortran program package suitable for modelling discrete systems. It consists of a chassis, the main program, into which calls to the modules, GPSS-FORTRAN's subroutines are inserted. Its construction makes it superior in several respects to its grandparent, GPSS. Other simulation languages and tools for the analysis of discrete systems such as SIMULA, SIMSCRIPT a...

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...

‘caffa3d.MB’ is a project under development since 2004, which includes a finite volume incompressible 3D fluid flow solver, with several extensions. caffa3d.MB is implemented in FORTRAN, mainly using standard FORTRAN 77 features, but also including some FORTRAN 95/90 extensions. Parallel programming techniques have been applied to caffa3d.MB through OpenMP directives to take advantage of shared...

Current Connection Machine (CM) Fortran codes developed for the CM-2 and the CM-5 represent an important class of parallel applications. Several users have employed CM Fortran codes in production mode on the CM-2 and the CM-5 for the last five to six years, constituting a heavy investment in terms of cost and time. With Thinking Machines Corporation’s decision to withdraw from the hardware busi...
