Abstract


Physically meaningful simulations in plasma physics and astrophysics need powerful hybrid supercomputers equipped with computation accelerators. The development of parallel numerical codes for such supercomputers is a complex scientific problem. In order to solve it the concept of co-design is employed. The co-design is defined as considering the architecture of the supercomputer at all stages of the development of the code. The use of co-design is shown by the example of two physical problems: the interaction of an electron beam with plasma and the collision of galaxies. The resulting speedup and efficiency are shown.
