Execution time is an important indicator of Service Level Agreement. Software as a Service providers expect to finish all queries before their respective deadlines and avoid penalties in violation of agreements. Hence, caching frequently occupied multi-tenant data is an efficient way of reducing execution time and penalty cost. However, it is difficult to minimize penalty cost through choosing cached...
With constant promotion and deepening of smart power grids, the data volume of power grid operation and equipment monitoring gain exponential growth and the environment of big data in electric system forms. Many platforms are deployed to meet different demands of equipment operation and maintenance. Since these platforms are independent and cannot be used in coordination, multi-sourced heterogeneous...
At present, power management in High-Performance Computing (HPC) environment is becoming a hot topic owning to its high operation cost, low reliability and environmental impact. In this paper, we investigate energy minimization scheduling algorithm of data dependent tasks in DVS-Enabled cluster system. Considering the data-intensive characteristics, the proposed EOTD (Energy Optimization scheduling...
At present, energy-efficient scheduling algorithm in High-Performance Computing (HPC) environment is becoming a research hotspot owning to its high operation cost and low reliability. In this paper, we investigate energy-efficient scheduling algorithm of data dependent tasks in DVS-Unable cluster system. The proposed ESTD algorithm efficiently integrates task clustering with task duplication technologies...
Service-oriented architecture builds software applications from large numbers of loosely coupled distributed services, while workflow technology coordinates these distributed services to achieve a shared task or goal. Scientific workflow is becoming researching hotspot along with the e-science and cyber-infrastructure applications, which run in the grid environment. Therefore, selection and scheduling...
Grid is an environment of seamless and integrated sharing and collaboration. The heterogeneous, dynamic, various and autonomous characteristics of resources make grid resource discovery a challenging issue. Hierarchical grid computing environment (hierarchical grid for short) with many advantages is far and wide used. This paper introduces small-world cluster into hierarchical grid in which intra-cluster...
The grid service has been used widely as a trend, and the scheduling algorithm for grid service has become a research focus. In this paper, a grid service scheduling architecture based on economic model (GSAEM) is proposed. The GSAEM introduces economic model into grid service scheduling, and deduces the optimal prices of grid service under every condition of resource constraints by marginal principle...
