Abstract

The next stage in high-performance computing is called exascale; this means that the coming generation of computers will be able to perform 1018 floating point operations per second! To make the simulation programmes that will run on these computers fit for these architectures, the EU is funding the Center of Excellence EXCELLERAT, in particular the coordinator, the High Performance Computing Centre Stuttgart (HLRS). In this project, six computational codes (Nek5000, Alya, AVBP, TPLS, FEniCS, Flucs) will be optimised and further developed to create new simulation tools for the engineering community at Exascale level. These programmes are particularly targeted at the aerospace, automotive, energy and manufacturing sectors, but the results of the project will also benefit other sectors during its lifetime. The developments will be implemented using concrete use cases from industry and will form the basis for the Centre of Excellence's offer to help developers of other simulation programmes to make them fit for the Exascale level as well. As the field of engineering is one of the industrial sectors with the highest exascale potential, EXCELLERAT bundles the existing European expertise for the establishment of a centre of excellence for highly scalable engineering applications. Through this, services such as networking, training, access to knowledge to technical services such as co-design, HPC, data management and scalability extension will be offered in the future. The talk will briefly introduce the EXCELLERAT project and then address the challenges faced by both developers and users of exascale applications.Example of use cases and their innovate solutions from automotive, aerospace, energy and manufacturing industrial sectors will be presented to show the future multiphysics simulations. Dialogue with experts and potential users will also be sought in order to assess their needs and to be able to include the required competences in the further course of the project.
