Reliability Analysis of OMEGA Network and Its Variants

The performance of a computer system depends directly on the time required to perform a basic operation and the number of these basic operations that can be performed concurrently. High performance computing systems can be designed using parallel processing. Parallel processing is achieved by using more than one processors or computers together they communicate with each other to solve a givenproblem. MINs provide better way for the communication between different processors or memory modules with less complexity, fast communication, good fault tolerance, high reliability and low cost. Reliability of a system is the probability that it will successfully perform its intended operations for a given time under stated operating conditions. From the reliability analysis it has beenobserved that addition of one stage to Omega networks provide higher reliability in terms of terminal reliability than the addition of two stages in the corresponding network.
