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.
