In grid computing, auction mechanisms have become a very important method in order to solve distributed scheduling problem. In this paper, we use the average budget formula to express the user preference. Meanwhile, we introduce the risk factor in utility function for improving the transaction successful rate. Our model has improved the resource allocation algorithm convergence by controlling the agent budget and risk. At last, we illustrate that our auction model can get very good results.

Power and energy consumption are important concerns in the design of high performance and mobile computing systems, but have not been widely considered in the design of parallel and distributed simulations. The importance of these factors is discussed and metrics for power and energy overhead in parallel and distributed simulations are proposed. Factors affecting the energy consumed by synchronization algorithms and software architectures are examined. An experimental study is presented examining energy consumption of the well-known Chandy/Misra/Bryant algorithm executing on a peer-to-peer mobile computing platform and compared with a centralized client-server approach using the YAWNS synchronization algorithm. Initial results concerning queueing network simulations are also presented. The results of this study suggest that existing distributed simulation algorithms require a significant amount of additional energy compared to a sequential execution. Further, different synchronization algorithms can yield different energy consumption behaviors.

Divisible workload applications arise in many fields of science and engineering. They can be parallelized in master-worker fashion and relevant scheduling strategies have been proposed to reduce application makespan. Our goal is to develop a practical divisible workload scheduling strategy. This requires that previous work be revisited as several usual assumptions about the computing platform do not hold in practice. We have partially addressed this concern in a previous paper via an algorithm that achieves high performance with realistic resource latency models. In this paper we extend our approach to account for performance prediction errors, which are expected for most real-world performance and applications. In essence, we combine ideas from multi-round divisible workload scheduling, for performance, and from factoring-based scheduling, for robustness. We present simulation results to quantify the benefits of our approach compared to our original algorithm and to other previously proposed algorithms.

Recent developments in high speed networks on both sides of the Pacific, including the vBNS, and the Abilene project in the US, and the Asia-Pacific Advanced Network (APAN) in the AP region, have been driven by the emergence of high speed networking as a central requirement for the support of basic science, engineering and other disciplines. The growth of international scientific collaborations in, for example, astronomy.
