Workshop on Readiness of HPC Extreme-scale Applications

In November 2022 the first ExaFLOPS supercomputer appeared in the Top500 list, after many years of pursuing the exa-scale goal, and several more are expected within the next year. Now is the time for application software to demonstrate its readiness for extreme-scale computer systems composed from large assemblies of a heterogeneous variety of CPU processors and GPU accelerators. Europe has been addressing this challenge for the last eight years through its Centres of Excellence (CoEs) for HPC applications, funded to greatly extend the scalability of a large selection of HPC codes and improve their efficiency and performance. To broaden this discussion to a larger community, this ISC workshop has been organised to provide a forum to consider common challenges, ideas, solutions, and opportunities from the point of view of HPC applications developers preparing for exa-scale. ISC is the leading HPC conference in Europe, gathering not only the main HPC vendors and providers but also developers and standardizing committees from programming models, compilers, and other system software. However, we still need one of the key players in this ecosystem, the HPC applications! With this workshop, we seek to cover this gap and expand the ISC conference to HPC code developers.
