Kokkos Tea time with W.Bangerth “Experience converting C++ to C++20 modules”

Wolfgang Bangerth give a talk entitled “Experience converting large scientific software packages written in C++ to C++20 modules”. Wolfgang Bangerth is a professor of mathematics and geosciences at Colorado State University, USA. He holds an undergraduate degree in physics, and a PhD in mathematics from Heidelberg University, Germany. As a graduate student in 1997, he co-founded the deal.II project (https://www.dealii.org), a widely used software library that provides finite element functionality. He is now one of the Principal Developers of the project. Experience converting large scientific software packages written in C++ to C++20 modules Many of the most widely used scientific software libraries are written in C++, but almost all of them still use the traditional header-based approach inherited from C to connect declarations provided in one file to uses and implementations in another file. On the other hand, C++20 introduces a module system that gives C++ a proper “import” statement that goes beyond the textual inclusion of “#include”. In this talk, Wolfgang outlines his experience with converting the deal.II finite element library – a library with 1.8M lines of C++ – to use C++20-style modules. He discusses how he does this from a technical perspective, and in particular how that actually works in practice.
