Closed-form solution for reliability of SCI-based multiprocessor systems using Weibull distribution and self-healing rings

Abstract

This paper introduces a new closed-form solution for the reliability of large-scale multiprocessor systems . The systems are based on SCI rings interconnected in hierarchical structures. Reliability expressions using enumeration technique are derived assuming Weibull failure process. The reliability function derived in this paper is general and valid for any hierarchical ring-based system with arbitrary number of levels. The hierarchical interconnections are constructed from self-healing rings and basic rings. The analysis shows the improvement achieved in reliability when self-healing rings are used. Although we used hierarchical systems based on SCI rings, the technique followed in this work is applied for any type of rings such as slotted or token rings .
