Software Defined Networking (SDN) is a new networking paradigm which provides better decoupling between control plane and data plane. The separation not only allows OpenFlow (OF) switches in the data plane simply to forward data, but also enables the centralized programmable controller to control the behavior of entire network. SDN makes it possible to manage the network more flexible and simple....
The MapReduce programming model has introduced simple interfaces to a large class of applications. Its easy-to-use APIs and autonomic parallelization are attracting attentions from scientific community. However, current MapReduce-style scientific frameworks focus more on the most popular MapReduce applications that can be easily partitioned and involve little communication across map or reduce tasks...
ExoGENI is a new GENI-federated Infrastructureas- a-Service (IaaS) framework. In this paper, we evaluate the performance of data-intensive applications on ExoGENI's resources. To simplify experiments, we design an automatic provisioning system called ExoApp. This paper focuses on MapReduce-based applications. Users can easily deploy applications in ExoGENI using ExoApp, without having to manually...
Structured adaptive mesh refinement (SAMR) techniques provide an effective means for dynamically concentrating computational effort and resources to appropriate regions in the application domain. However, due to their dynamism and space-time heterogeneity, scalable parallel implementation of SAMR applications remains a challenge. This paper investigates hybrid runtime management strategies and presents...
