3E: Energy-Efficient Elastic Scheduling for Independent Tasks in Heterogeneous Computing Systems

Reducing energy consumption is a major design constraint for modern heterogeneous computing systems to minimize electricity cost, improve system reliability and protect environment. Conventional energy-efficient scheduling strategies developed on these systems do not sufficiently exploit the system elasticity and adaptability for maximum energy savings, and do not simultaneously take account of user expected finish time. In this paper, we develop a novel scheduling strategy named energy-efficient elastic (3E) scheduling for aperiodic, independent and non-real-time tasks with user expected finish times on DVFS-enabled heterogeneous computing systems. The 3E strategy adjusts processors’ supply voltages and frequencies according to the system workload, and makes trade-offs between energy consumption and user expected finish times. Compared with other energy-efficient strategies, 3E significantly improves the scheduling quality and effectively enhances the system elasticity

Deformational Mechanism and Tectonic Evolution of Mesozoic-Cenozoic Nonmarine Basins from Bohai Bay Basin - China

Bohai Bay Basin，China, is a rift basin developed in Mesozoic-Cenozoic time span. It was compressionally deformed during Caledonian Orogeny and situated on a Paleozoic platform “old craton” basement and later subjected to extensional stress and induced major strike-slip (wrench) fault. The basin opening transpired on a series of half-grabens trending NNE-SSW in Bohai Bay Basin zone. Models for deformational mechanism and evolution of the Bohai Bay Basin, China, and its tectonic and stratigraphic history were proposed. Two separate scenarios were set for the evolution of Bohai Bay Basin: the first is based on the changes in plate convergence rates along the eastern plate boundary of Eurasia/ Pacific plates which have additional role in the extensional skin of Bohai Bay Basin in certain stage of extension or rifting and the second is a model of three major incidents of extensional tectonism: basement pre-rifting, a syn-rift stage, and a post-rift sag stage were documented for Bohai Bay Basin. The major factor controlling the lacustrine basins is global eustasy; however, the role of global tectonic played a significant control mechanism in the evolution and development of Bohai Bay Basin

A novel optimization method on logistics operation for warehouse & port enterprises based on game theory

Purpose: The following investigation aims to deal with the competitive relationship among different warehouses & ports in the same company. Design/methodology/approach: In this paper, Game Theory is used in carrying out the optimization model. Genetic Algorithm is used to solve the model. Findings: Unnecessary competition will rise up if there is little internal communication among different warehouses & ports in one company. This paper carries out a novel optimization method on warehouse & port logistics operation model. Originality/value: Warehouse logistics business is a combination of warehousing services and terminal services which is provided by port logistics through the existing port infrastructure on the basis of a port. The newly proposed method can help to optimize logistics operation model for warehouse & port enterprises effectively. We set Sinotrans Guangdong Company as an example to illustrate the newly proposed method. Finally, according to the case study, this paper gives some responses and suggestions on logistics operation in Sinotrans Guangdong warehouse & port for its future development.Peer Reviewe
