Software for exascale computing - SPPEXA 2016-2019

Abstract

This volume summarizes the research done and results obtained in the second funding phase of the Priority Program 1648 “Software for Exascale Computing” (SPPEXA) of the German Research Foundation (DFG). In that respect, it both provides an overview of SPPEXA’s achievements and represents a continuation of Vol. 113 in Springer’s series “Lecture Notes in Computational Science and Engineering”, the corresponding report of SPPEXA’s first funding phase. For some general remarks on the uniqueness of SPPEXA—as the first strategic, i.e. board-initiated Priority Program of DFG; as the first tri-national Priority Program with synchronized collaborative research in Germany, France, and Japan; as a multi-disciplinary endeavor involving informatics and mathematics, but also various fields from engineering, the sciences, and the life sciences; and as the first holistic approach to research on High-Performance Computing (HPC) software at the level of fundamental research—we refer to the overview contribution of Bungartz et al. (see chapter “Software for Exascale Computing: Some Remarks on the Priority Program SPPEXA”) in this volume. There, also some statistics are provided. The spirit of the international collaboration, whether in a bi-lateral (German– Japanese) or in a tri-lateral (French–Japanese–German) setting, can be found and felt in several of the reports of 16 out of 17 SPPEXA consortia. This structured and institutionalized collaboration was not easy to establish, and we are grateful for the shared enthusiasm, commitment, and support of the three involved funding agencies: the German Research Foundation (DFG), the Agence Nationale de la Recherche (ANR), and the Japan Science and Technology Agency (JST). The synergies emerging from bringing together the expertise of groups from three countries did not only boost the respective project work itself, it also prepared the ground for ongoing partnerships as well as for a topical extension towards the interplay of HPC and Artificial Intelligence—a field that both benefits tremendously from HPC and, at the same time, fosters HPC with new concepts.
