Abstract
Abstract: Distributed computing systems are of current interest due to the advancement of microprocessortechnology and computer network. The prime function of effective utilization of distributed system is accuratelymapping of task and tasks their scheduling on different processors for reducing their total finish time. Totalruntime is taken time for all module with the runtime of tasks and their communication cost among tasks. InDistributed processing system, partitioning of a task into modules and proper allocation of module amongprocessors are more important factor for efficient utilization of resources. In this paper, we discuss allocation ofa set of ‘m’ module of a task to a set of ‘n’ processors (where m > n) to get an optimal utilization of availableprocessors. We partition the task in different size of module and design an algorithm for allocation of thesemodules in distributed processing environment. While designing the model Per Bit Processing Rate, Inter TaskCommunication Cost, Task Size has been taken into consideration. We consider the constraints of minimizingexecution cost and their Inter task communication and maximize the overall throughput of the system to betaking as constraints in such a way that allocated load on all the processor is balances.
