Design and Reliability Evaluation of Switching Element for Improving the QoS of Multistage Interconnection Network
Shilpa Gupta · ECS Transactions · 2022
Reliable and cost effective multistage interconnection networks (MINs) are the backbone of efficient distributed computing in supercomputer systems. In this paper new 3×3, 4×2, and 4×4 switching element (SE) structures are introduced which can be employed in various existing MINs to provide enhanced reliability at much reduced cost. The reliability function of proposed as well as the existing SEs have been formulated on basis of which their reliability values have been computed. The computed reliability values of all SEs (existing and proposed ones) have been compared and analyzed. The achieved results clearly depicts that the proposed SEs possess higher reliability and can replace the existing SEs of similar size without changing the existing design of MIN to improve reliability.
