Fortran to Lisp Translation using f2cl

The need for both algebraic and numerical capabilities within mathematical computation systems has highlighted the need to translate numerical software written in Fortran77 to Common Lisp, a language favoured by the algebraic computation community. This paper reports the current state of f2cl, a translator written to achieve that end. We describe the translation process giving details of Lisp equivalents of Fortran expressions, as well as discussing features of Fortran that have no straightforward equivalent in Lisp.     

A Fortran to Pascal translator

This paper describes some of the problems encountered in implementing an automatic Fortran to Pascal translator. The translator introduces a number of improvements to the Fortran program including the structured control statements of Pascal. It highlights the structure of both COMMON blocks and executable statements, and it nests the Fortran subprograms to their required level.

A Comparison of Co-Array Fortran and OpenMP Fortran for SPMD Programming

Co-Array Fortran, formally called F^––, is a small set of extensions to Fortran 90/95 for Single-Program-Multiple-Data (SPMD) parallel processing. OpenMP Fortran is a set of compiler directives that provide a high level interface to threads in Fortran, with both thread-local and thread-shared memory. OpenMP is primarily designed for loop-level directive-based parallelization, but it can also be used for SPMD programs by spawning multiple threads as soon as the program starts and having each thread then execute the same code independently for the duration of the run. The similarities and differences between these two SPMD programming models are described.Co-Array Fortran can be implemented using either threads or processes, and is therefore applicable to a wider range of machine types than OpenMP Fortran. It has also been designed from the ground up to support the SPMD programming style. To simplify the implementation of Co-Array Fortran, a formal Subset is introduced that allows the mapping of co-arrays onto standard Fortran arrays of higher rank. An OpenMP Fortran compiler can be extended to support Subset Co-Array Fortran with relatively little effort.     

An experiment with Fortran and Pascal

This paper reports on a programming experiment involving the languages Fortran and Pascal. The subject of the experiment was the simulation of the X-ray department of a local hospital. The programming was carried out by two different programmers at different periods of time. A static analysis was performed on both models to determine how the languages were used by both programmers. The compilation and execution speeds of both models were then determined when executed on an ICL 1906S computer. The results indicate that the Pascal program is substantially faster in both compilation and execution speed than an equivalent Fortran program.
