Abstract
Several recent studies discuss potential Exascale architectures, identify key technical challenges and describe research that is beginning to address several of these challenges [1,2]. Co-design is a key element of the U.S. Department of Energy’s strategy to achieve Exascale computing [3]. Architectures research is needed but will not, by itself, meet the energy, memory, parallelism, locality and resilience hurdles facing the HPC community – system software and algorithmic innovation is needed as well. Since both architectures and software are expected to evolve significantly there is a potential to use the co-design methodology that has been developed by the embedded computing community. A new co-design methodology for high performance computing is needed.
