High-performance computing has been recognized both by the German as well Indian government as a major driver of innovation and research. Germany is operating multiple supercomputers in the multi-PFlop/s performance range, while India recently announced a large-scale program to realize a national-wide supercomputing infrastructure. In both countries scientists are performing research on reaching the next levels of performance, i.e. exascale compute capabilities. This concerns both research in computer architectures as well as in applications and suitable algorithms. Exascale can only be reached through an extreme increase of parallelism, which results in numerous challenges, like keeping system architectures balanced, improving energy efficiency significantly or enable even more scalable applications and algorithms. A commonly accepted approach to deal with these challenges involves co-design between computer architecture and technology experts as well as experts for scientific applications and algorithms. This workshop will bring together such experts from different fields from German and India.
