The virtualization technology makes it feasible that multiple guest operating systems run on a single physical machine. It is the virtual machine monitor that dynamically maps the virtual CPU of virtual machines to physical CPUs according to the scheduling strategy. The scheduling strategy in Xen schedules virtual CPUs of a virtual machines asynchronously(More)
System virtualization can aggregate the functionality of multiple standalone computer systems into a single hardware computer. It is significant to virtualize the computing nodes with multi-core processors in the cluster system, in order to promote the usage of the hardware while decrease the cost of the power. In the virtualized cluster system, multiple(More)
Considering dynamic, heterogeneous and autonomous characteristics of computing resources in grid computing systems and the flexibility and effec-tivity of economics methods applied to solve the problem of resource management , a double auction mechanism for resource allocation on grid computing systems is presented. Firstly, a market model of double auction(More)
With multi-core processors becoming popular, exploiting their computational potential becomes an urgent matter. The functionality of multiple standalone computer systems can be aggregated into a single hardware computer by virtualization, giving efficient usage of the hardware and decreased cost for power. Some principles of operating systems can be applied(More)
—Recent cost analysis shows that the server cost still dominates the total cost of high-scale data centers or cloud systems. In this paper, we argue for a new twist on the classical resource provisioning problem: heterogeneous workloads are a fact of life in large-scale data centers, and current resource provisioning solutions do not act upon this(More)
The economic mechanism is very suitable for solving the problem of resource management in the grid computing environment, and it can guarantee the interest ofparticipators in the grid with fairness and efficiency. In this paper, we propose an economics-based resource management framework for grid computing, and then wefocus on how to determine the price of(More)
