SDN in high performance computing for scientific and business environment (SBE)

In recent scenario, need of computing is shifting towards High Performance Computing (HPC) not only for scientific applications but in commodity applications also. HPC cluster system allows HPC users to analyze and solve complex problems that are associated with large data size, such as big data simulation and big scale scientific simulation for quick analysis. It is highly required in the domain of science and industry for enhancing accuracy. Today, cluster system approach in demand for HPC systems rather than main frame system, cluster is a system of multi-core multiple computers interconnected in network. HPC apart from interconnect includes multiple standalone computers (PCs, Workstations, or SMPs) are based on processor technologies (like Intel, IBM P6, SUN SPARC etc.), RAM, and motherboard architecture, further operating systems, middleware, parallel programming environments enhance it. In this paper, key factors like processor micro architecture(Ivy Bridge, Haswell), inter-core communication performance, inter-socket communication performance (Quick Path Interconnect) and inter-rack communication through 10 Gbps and Infinband's DDR and FDR performance and challenges are reviewed to improve and meet businesses need with incorporating Software Defined Networking (SDN) in HPC scenario.
