Joint meeting with Computational Physics Group of Institute of Physics

CoArrays in GNU Fortran
Salvatore Filippone, Cranfield University

We discuss the current status of the CoArrays implementation in GNU Fortran, through the experience of the OpenCoarrays project, with a selection of use cases. We also discuss the influence of various transport layers, including a discussion of the variations among multiple implementation of the MPI standard.

Verification of Fortran codes
Wadud Miah, Computational Scientist, Numerical Algorithms Group

Fortran is a popular language for computational science codes which typically run on large supercomputers. With the advent of large Petascale machines, there is a strong emphasis on parallel scalability and energy efficiency. However, knowledge of verification of Fortran codes is lacking and there is anecdotal evidence to suggest that there is an over-reliance compilers to verify codes. This presentation will introduce a simple verification workflow and present the NAG compiler and verification tools for Fortran codes.

Afternoon tea

Compiler conformance to the Fortran 2003, 2008 standards and TS29113.
Ian Chivers, Rhymney Consulting and Jane Sleightholme, Fortranplus

We will review how well current compilers comply with current standards.

The new features of Fortran 2015
John Reid, past Convenor ISO WG5

I will provide a quick overview of the new features of Fortran 2015. For details, see N2127 on the WG5 site.

Choosing the technical content for Fortran 2020
Anton Shterenlikht, Mech Eng Dept, The University of Bristol

The process for choosing the technical content of Fortran 2020 has been agreed, in principle, at the Summer 2017 WG5 meeting in Garching, Germany (N2135, N2126). A user survey is now open, the results of which will be analysed by J3, and help prioritise proposed new features. However, real use cases must be provided to support all new feature requests, and costs of implementation will be taken into account when WG5 decides the final set of new features for 2020. This talk will expand on the WG5 thoughts behind these decisions and introduce the user survey.

Exception handling
John Reid, past Convenor ISO WG5

One of the suggested features for Fortran 2020 in the new convener's survey is "Block-oriented or structured exceptions". Such a feature was included in 1994 drafts of Fortran 95, but was removed in November 1994 because it was seen as not ready and likely to delay Fortran 95. It was decided instead to provide features in support of the IEEE standard for floating-point arithmetic, but it was envisaged that structured exceptions could be added later. In this talk, I will describe the 1994 facility and discuss its adaptation as an extension of Fortran 2015.


All current Fortran SG members are welcome to attend the AGM. The afternoon presentations are open to all, including non-BCS members.
Attendance is free of charge but please book your place via the BCS online booking system to ensure your admission to the Davidson building and your lunch if you want one.
