High performance computing (HPC) has begun scaling beyond the Petaflop range towards the Exaflop (1000 Petaflops) mark. One of the major concerns throughout the development toward such performance capability is scalability both at the system level and the application layer. In this paper we present a novel approach for a new design concept the Co Design approach with enables a tighter development of both the application communication libraries and the underlying hardware interconnect solution in order to overcome scalability issues and to enable a more efficient design approach towards Exascale computing. We have suggested a new application programing interface and have demonstrated a 50x improvement of performance and scalability increases.
