From concept to engineering, and from design to test and manufacturing, the automotive industry relies on powerful virtual development solutions. CFD and crash simulations are performed in an effort to secure quality and accelerate the development process. The recent trends in cluster environments, such as multi-core CPUs, GPUs, cluster file systems and new interconnect speeds and offloading capabilities are changing the dynamics of clusteredbased simulations. Software applications are being reshaped for higher parallelism and hardware configuration for solving the new emerging bottlenecks, in order to maintain high scalability and efficiency. In this paper we cover a new co-design architecture with hardware based accelerations and offloads for MPI collectives communications and how it affects LS-DYNA performance.

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.
