Resumen
Refactoring is a software engineering technique that aims at improving the internal structure of an application, in such a way that the changes do not interfere in the results
produced by the software. This technique is permanently employed in the software life cycle and refers to non-functional characteristics as legibility and performance. Most refactoring techniques currently apply to object-oriented systems and are widely available in integrated development environments for this programming paradigm. In high performance computing applications, code refactoring is a little-explored technique, as a great amount of legacy high performance code was written before the widespread use of object-oriented languages. The Fortran language (FORmula TRANslator) is heavily used in high performance applications, but has a few and limited tools for code refactoring. In such context, our work explores this open research area through the development of
new techniques for refactoring Fortran source code. Our development starts from identifying refactoring opportunities for Fortran code and extends the Photran tool, which is an Eclipse IDE plugin for Fortran programming. The new automated refactoring techniques
are applied to third-party code written in Fortran, in order to evaluate their impact on the software performance.
