Project

The Jülich Supercomputing Centre (JSC), as part of the FZJ, operates one of the most powerful supercomputer infrastructures in Europe and makes it available to researchers in NRW, Germany, and Europe. In mid-2022, it was also announced that the application by the Gauss Center for Supercomputing, with the FZJ as the site for the first European Exascale Supercomputer, was successful. This will allow the first European supercomputer to be directly usable by the FZJ within the duration of this project and be realized in new FEATFLOW versions, which are sustainably capable of exploiting the high performance of future EXASCALE computer architectures and making them available for StrömungsRaum®. By involving the Simulation and Data Laboratory "Highly-Scalable Fluids & Solids Engineering" of the Jülich Research Center, the partners also aim to build an Exascale Community in this area with a view to the first European Exascale supercomputer, in order to pass on, deepen and broaden the expertise gained. Challenges in this area arise in high degrees of scaling, heterogeneous and complex node architectures with deep memory hierarchies (including HBM memories in the CPU area) and the growing breadth in CPU processors (especially in the area of x86- and ARM-based systems), GPU processors (NVIDIA, AMD, Intel Ponte Vecchio) and heterogeneous, flexible concepts such as the EPI. The project follows a co-design approach that can qualitatively or quantitatively evaluate the efficiency of alternatives in algorithms, data structures, and implementations with respect to fundamental architectural properties with performance models (e.g., using SIMD-like concepts or new memory hierarchies/technologies), thereby allowing a targeted selection.
