Given the research and development man-years spent on scientific applications, this risk shou ld make the HPC community consider more sustainable and long-term developm ent strategies. A case in point is the GPU development, where one must dec ide carefully the platform to target, e.g., CUDA, OpenCL, ROCm. On the oth er hand, there exist few examples of software that is agnostic to the unde rlying architecture, offering the possibility of a single code to deal wit h multiple architectures. Currently, scientists and engineers often develo p their applications for a very specific architecture, spending valuable t ime optimizing and tailoring their codes. Furthermore, as the code moves t o different platforms with different accelerators, the code branches into multiple development streams, where each of them is dealing with its own p latform-specific issues that are solved with diverging techniques. Thus, i t is critical to open a wide discussion on frameworks, inherently parallel programming languages, compilers, platforms and a combination of them, th at will help the community choose a development pipeline, leading to HPC m odels that favor flexible, versatile and sustainable solutions.\n\nSolver- Agnostic Coupling for Multiscale and Multiphysics Simulations\n\nKiči ć, Pezzè, Salza, Koumoutsakos\n\nMultiscale and multiphysics coupling methodologies offer great promise for extending the size and complexity o f natural systems tractable to computer simulations. However, the coupling of diverse software solvers in a reusable fashion, in particular in an HP C framework, is an open problem.

That can be a challenge in the current era of new hardware architec tures, programming paradigms and constantly changing software.The cloud gi ves rise to a new paradigm f...\n\n---------------------\nFuthark: Painles s HPC on GPUs\n\nMalaspinas, El-Kharroubi\n\nThe advent of new HPC archite ctures such as GPUs often challenges the long known CPU-based best practic es. They usually offer a great improvement in performance at the cost of r equiring a deep understanding of the hardware from the developer who needs to perform very precise optimizations.
