Task Scheduling & Energy Conservation Techniques for Multiprocessor Computing Systems

The need for robust power-performance has enabled designers to make right direction in designing and developing the energy efficient scheduling techniques, as there is a strong need of scheduling algorithms which lowers the energy consumption and yet attain good schedules. Over the years, there has been a lot of research in scheduling the tasks for minimal schedule length and low time complexity, still little work has addressed the issues of both makespan and energy conservation together, especially for heterogeneous distributed computing system. Existing scheduling strategies for high performance computing systems provide versatile, low cost performance at the expense of huge energy consumption. This paper addresses the “state of the art” in energy aware scheduling techniques for dependent tasks in multiprocessor systems to reduce the overall makespan and reduction in energy consumption.
