Objective
The objective of this application experiment is to train personnel in applying software tools (primarily NAGWare f77, f90 parallelisation tools) to ensure quality, maintainability and portability of large Fortran 77 and Fortran 90 codes and to investigate, test and improve the tools required to upgrade such code to use Fortran 90 constructs. Moreover, parallelisation tools are tested, aiming at easier parallelisation.
THE EXPERIMENT
The achievement of the objectives above requires the improvement of quality procedures, and better usage of standard in the programming environment.
This is implemented as follows:
- Usage of Fortran 77 syntax checking tools and reformatting tools, the NAGWare f77 tools.
- Usage of Fortran 77 to Fortran 90 conversion tools, the NAGWare f90 tools.
- Creation of a handbook with standards for programming in Fortran 77 or 90.
- Usage of a Fortran parallelisation tool, the FORGE browser and distributed memory paralleliser.
The tools are used on two seismic processing applications, which were in part developed at TNO. These applications are written in Fortran 77, but underlying libraries are also written in C.
The group Information Systems Oil and Gas consists of 10 persons, of whom 3 are involved in this ESSI project. Information Systems Oil and Gas is a section of Geo Energy, one of the 4 departments of the TNO Institute of Geoscience.
EXPECTED IMPACT AND EXPERIENCE
TNO expects to produce software that will be easier to port and maintain, and which will be parallelised with one interactive parallelisation tool. Because of the tools used, programmers should be more aware of the standards, and use these to produce better and portable code.
