Reconfiguration of the Multi-channel Communication System with Hierarchical Structure and Distributed Passive Switching

Abstract

One of the key problems in parallel processing systems is the architecture of internodal connections, thus affecting the computational efficiency of the whole. In this work authors describe proposition of a new multi-channel hierarchical computational environment with distributed passive switching. According to authors, improvement of communication efficiency should be based on grouping of system components. In the first type of clustering processing nodes are combined into independent groups that communicate using a dedicated channel group. The second type of clustering splits channels available in the system. In particular, they are divided into smaller independent fragments that can be combined into clusters that support selected users. In this work, a model of computational environment and basic reconfiguration protocol were described. The necessary components and management of reconfiguration, passive switching and hierarchization were discussed, highlighting related problems to be solved. Main reconfiguration restrictions were specified, using and combining together two structural complexity measures: Complexity B Index and Efficiency Index.
