Recent initiatives to increase the performance and flexibility of modular platforms aimed at high-performance embedded computing (HPEC) are bearing fruit by enabling board and system designers to use high-speed switched fabrics from mainstream high-performance computing (HPC) markets to maximize performance, reduce technical risk and shorten time to solution for advanced military and aerospace applications. This white paper explores how system integrators can leverage the switched fabric networking technologies found in HPC systems in the development of military and aerospace applications.
