Paving the Road towards Pre-Exascale Supercomputing

Supercomputing at scale has become the decisive challenge for users, providers and vendors ofleading supercomputer systems. On next-generation systems, approaching exascale by the endof the decade, we will be confronted with millions of cores, and the need of massive parallelism.Beyond aggregating ever larger compute performance also the ability to hold and efficientlyprocess drastically increasing amounts of data will be key to enable future leading researchfacilities for computational science. We report in this article on the evolving supercomputinginfrastructure at Jülich Supercomputing Centre (JSC), research and development activities onfuture HPC technologies and architectures as well as on the computational science research andcollaboration with science areas which will require exascale supercomputing in the future
