Co-Design of Systems and Applications for Exascale (Dagstuhl Perspectives Workshop 12212)

The Dagstuhl Perspectives Workshop 12212 on "Co-Design of Systems and Applications for Exascale" is reaching into the future, where exascale systems with their capabilities provide new possibilities and challenges. The goal of the workshop has been to identify concrete barriers and obstacles, and to discuss ideas on how to overcome them. It is a common agreement that co-design across all layers, algorithms, applications, programming models, run-time systems, architectures, and infrastructures, will be required. The discussion between the experts identified a series of requirements on exascale co-design efforts, as well as concrete recommendations and open questions for future research.
