Bâtiment 565 - Digiteo CEA Saclay 91191 Gif-sur-Yvette

This course is offered in cooperation with NAG

This two day practical hands-on workshop is aimed at Fortran programmers who want to write modern code, or to modernize existing codes, to make it more readable and maintainable by encouraging good software engineering practices. This workshop will also present how to integrate tools and techniques for Fortran codes to help you develop sustainable software for your scientific and academic research particularly in a collaborative environment. Overall, the aim is to make you a better and more productive computational scientist by improving your applied computer science skills that are directly relevant to computational science.
