摘要：Distributed computing systems (DCS) are of current interest due to the advancement of microprocessor technology and computers networks. It consists of multiple computing nodes that communicate with each other by message passing mechanism. Reliability and communication over distances are the main reasons for building the DCS. In distributed computing systems, partitioning of applications software in to modules and proper allocation of modules among processors are important factors for efficient utilization of resources. We consider the problem of m-modules and n-processors (m >> n). In this paper a mathematical model for finding optimal cost and optimal reliability to the problem is presented considering DCS with heterogeneous processors in such a way that the allocated load on each processor is balanced. The results obtained by the present model are compared with the recent models and comparison results show that the model is very effective.
