European Processor Initiative: the European approach for Exascale ages

J.M. Denis, ATOS/EPI (FR)

Abstract: The rise of artificial intelligence in HPC, associated to the data deluge, combined to the transition from monolithic applications toward complex workflows and dataflows lead the HPC community, especially the hardware architects to reconsider how the Exascale supercomputers are designed. Furthermore, the advent of hybrid computing, defined as the combination of in-house with cloud computing significantly impacts design metrics.
This presentation discussed the transition from existing homogenous to Exascale class modular architectures. The consequences on the compute components including the general-purpose processor and the associated accelerators were addressed. Ultimately, all these considerations lead to the guidelines having ruled the design of the European microprocessor that will empower the European Exascale supercomputers.
