Improved Meta-Flattened Butterfly Multistage Interconnection Network

Abstract

processing is efficient form of information processing which means to implement high performance computing systems. A communication network that links processors and memory modules determines the efficiency of these parallel systems. To provide the required connectivity and performance at reasonable cost, an interconnection network is used. Hence, multistage interconnection networks are a good way for providing communication in these systems. This paper includes two major contributions. Firstly, it describes the flaws of existing Meta- flattened Network (MFN). Secondly, a new Fault-tolerant multistage interconnection network named as Improved Meta- Flattened Butterfly Network (IMFN) is proposed that can improve the routing problems of Meta-flattened Network. Performance of the proposed network is analyzed in terms of cost and permutation possibility. The performance comparison of the IMFN with MFN shows that the proposed network IMFN gives much better performance in terms of permutation.
