“…The performance was evaluated by studying their impact on scheduling divisible load applications. To schedule such application, a greedy scheduling technique, similar to the one presented previously (Abouelela and El-Darieby, 2011), has been used. Simulations were conducted using OMNET++ network simulator (www.omnetpp.org).…”

Providing interoperability in multi-domain optical grids requires sharing resource information among different domains. Sharing full resource information may not be appropriate due to security and business confidentiality reasons. We propose resource information sharing approach based on information aggregation and abstraction for both computing and networking resources. Information aggregation and abstraction affects the overall accuracy of information representation. This calls for more accurate information abstraction techniques. We propose three abstraction techniques: direct formulas, historical data and real-time measurements. The performance of the proposed information sharing approach and the abstraction techniques is evaluated by studying their impact on scheduling divisible load grid applications. Simulation results highlight the advantages of the proposed approach specially for data intensive applications. By using the proposed abstraction techniques, the same performance could be achieved as using large volumes of exact information.Reference to this paper should be made as follows: Abouelela, M. and El-Darieby, M.

Geographically distributed applications in grid computing environments are becoming more and more resource intensive. Many applications require the collaboration between different domains, may be independently administrated domains, to exchange data and share computing and storage resources. This collaboration should be done in a way that maintains the privacy of each participant domain. This calls for new architectures and approaches to deal with such multidomain environments. We propose a hierarchical-based architecture as well as multidomain hierarchical resource allocation approach. The resource allocation is performed in a distributed way among different domains such that each participant domain keeps its internal topology and private data hidden while sharing abstracted information with other domains. Both computing and networking resources are jointly scheduled while optimizing the application completion time taking into account data transfer delays. Simulation results show the scalability and feasibility of the proposed approach.

“…Other similar applications include database search problems , linear algebra , and multimedia broadcasting . Because of the ideal characteristics of divisible loads, they are widely used in many parallel and distributed systems based on interconnected networks, such as cloud computing , computational grids , parallel clusters , wireless sensor networks , and other heterogeneous distributed systems . It is very meaningful to use DLT when studying an energy‐aware scheduling algorithm, and we investigate divisible loads in this paper.…”

SUMMARYThe schedule of divisible loads is one of the most typical problems in the research and application of parallel and distributed systems. For these large-scale systems, the energy consumption problem has drawn great attention in recent years because of falling hardware costs and the growing concern of energy costs. In computing-intensive systems, energy is primarily consumed by CPUs, and dynamic voltage-frequency scaling technology is capable of adjusting CPUs' speed as well as saving energy. In this paper, we focus on computing-intensive applications and study the energy-aware scheduling problem for divisible loads in a bus network. The energy-speed model is introduced to characterize the problem based on dynamic voltage scaling, and the energy-aware scheduling problem is analyzed in the application layer above the operating system. The problem can be formulated mathematically as a nonlinear programming problem, and the solution is achieved using the Lagrange multiplier method under Kuhn-Tucker conditions. Based on the analytical results, an energy-aware scheduling scheme called ENERG for divisible loads is presented. Finally, the energy-aware scheme is compared with two other schemes to show the effectiveness and efficiency of the energy savings of our algorithm. Additionally, the experimental results illustrate the influence of network transmission delay on energy consumption.
