Energy Conscious Scheduling for Distributed Computing Systems under Different Operating Conditions


Energy Conscious Scheduling for Distributed
Computing Systems under Different
Operating Conditions
Abstract:
Traditionally, the primary performance goal of computer systems has focused on reducing the execution time of applications while increasing throughput. This performance goal has been mostly achieved by the development of high-density Computer systems. As witnessed recently, these systems provide very powerful processing capability and capacity. They often consist of tens or hundreds of thousands of processors and other resource-hungry devices. The energy consumption of these systems has become a major concern. In this paper, we address the problem of scheduling precedence-constrained parallel applications on
Multiprocessor computer systems and present two energy-conscious scheduling algorithms using dynamic voltage scaling (DVS). A number of recent commodity processors are capable of DVS, which enables processors to operate at different voltage supply levels at the expense of sacrificing clock frequencies. In the context of scheduling, this multiple voltage facility implies that there is a trade-off between the quality of schedules and energy consumption. To effectively balance these two performance goals, we have devised a novel objective function and a variant from that. The main difference between the two algorithms is in their measurement of energy consumption. The extensive comparative evaluations conducted as part of this work show that the performance of our algorithms is very compelling in terms of both application completion time and energy consumption.

Existing System:

Ø In the existing system Most MCSs operate with some form of resource management facility (such as PBS, LSF, etc.) for achieving performance goals like high performance, high throughput and/or high availability.
Ø However, most existing resource management facilities generally lack energy saving capability.
Ø  The size of adverse environmental footprint that MCSs leave.

Proposed System:

Ø In this paper, we address the problem of scheduling precedence-constrained parallel applications on multiprocessor computer systems and present two energy-conscious scheduling algorithms.
Ø Presents two energy-conscious scheduling heuristics that take into account not only make span, but also energy consumption.
Ø The extensive comparative evaluations conducted as part of this work show that the performance of our algorithms is very compelling in terms of both application completion time and energy consumption.
Ø We address the energy-aware scheduling of precedence-constrained parallel applications for MCSs consisting of heterogeneous resources.
Ø However, most efforts in task scheduling have focused on two issues, the minimization of application completion time (make span/schedule length) and time complexity; in other words, the main objective of a task scheduling algorithm is the generation of the optimal schedule for a given application with the minimal amount of scheduling time.
