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...
Complicated method and technology have been introduced into business workflow to solve their cooperation and load balancing. However, as combination of data management and flow management, scientific workflow's load balancing is less researched. So the phenomena of conflicting scheduling and load unbalance often occur. In this paper, we analyze functional framework and load consumption of scientific...
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...
One of the important issues in the design of future generation high-speed networks is to provide differentiated services to different types of traffic with/without various time constraints and priorities. In this paper, we study the problem of providing differentiated services in passive star coupled wavelength division multiplexing (WDM) optical networks. We suggest a simple static priority based...
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...
Tuning latency and scheduling latency are two major overheads when designing medium access control (MAC) protocols for single hop passive star-coupled WDM optical network. Some schemes proposed so far has considered these two overheads, however, they cannot remove these two overheads completely, especially the overhead caused by receiver. To reduce the negative impact of tuning latency and scheduling...
In this paper, a local optimization framework is proposed, which is able to include system constraints, i.e., channel availability, receiver availability and tuning overhead, by linear mathematical formulations so that it is sufficient to obtain the optimal performance in terms of message loss rate. A mixed integer linear programming (MILP) based optimal scheduling scheme has been proposed. Based...
