To tackle with all of them without sacrificing performance, traditional approaches in resource utilization, task scheduling and programming paradigm should be reconsidered. While Hadoop has handled data-intensive applications well in Clouds, GPU has demonstrated its acceleration effectiveness for computation-intensive ones. This paper addresses the approaches for Hadoop to exploiting both CPU and GPU resources effectively to handle aforementioned challenges. Hadoop schedules MapReduce’s Map and Reduce functions across multiple different computing nodes through Java, whereas CUDA code helps accelerate local computations further on attached GPUs. All available heterogeneous computational power will be utilized. MapReduce in Hadoop eases the programming task by hiding communication and scheduling details. Hadoop Distributed File System will help achieve data-level fault resilience. GPU’s energy efficiency characteristics help reduce the power consumption of the whole system. To utilize GPU in Hadoop, four approaches including Jcuda, JNI, Hadoop Streaming, and Hadoop Pipes, have been accomplished and analyzed. Experimental results have demonstrated and compared their effectiveness.","PeriodicalId":318936,"journal":{"name":"Int. J.

It provides a fundamental means to master systems complexity, by allowing to design systems parts (i.e., components) for reuse and by allowing to develop those parts independently. One of the main challenges of introducing CBSE in this area is to ensure the integrity of the overall system after building it from individual components, since safety-critical systems require a rigorous development and qualification process to be released for the operation. Although the topic of compositional modelling and verification in the context of component-based systems has been studied intensively in the last decade, there is currently still a lack of tools and methods that can be applied practically and that consider major related systems quality attributes such as usability and scalability. In this paper, we present a novel approach for design-time modelling and verification of safety-critical systems, based on data semantics of components. We describe the composition, i.e., the systems design, and the underlying properties of components as a Constraint Satisfaction Problem (CSP) and perform the verification by solving that problem. We show that CSP can be successfully applied for the verification of compositions for many types of properties. In our experimental setup we also show how the proposed verification scales with regard to the complexity of different system configurations.","PeriodicalId":318936,"journal":{"name":"Int. J.

Since in many applications the WSN nodes are randomly deployed, WSNs need to be able to arrange and self-organize. Nodes in WSNs generally possess low or limited power resources such as batteries. Energy utilization thus is an important design consideration for WSN deployment. There have been many energy aware protocols proposed in the literature to increase the longevity of the network. Recently, two novel Connected Dominating Set (CDS) based topology construction (TC) protocols- SWST (Simple Weighted Spanning Tree) and EAST (Energy Aware Spanning Tree), have been proposed which aim to balance the load among the nodes of the network and thus to reduce the probability of dying for a particular node. The SWST and EAST protocols aim to reduce the number of broken links that may have been caused by a single node becoming dead or comatose in the communication backbone of the network. In this paper, a comparative study of the SWST and EAST algorithms is conducted to evaluate the performance of the two algorithms. From the MATLAB simulations it was observed that the EAST protocol generally performs better than the SWST algorithms in delivering messages to the sink node.","PeriodicalId":318936,"journal":{"name":"Int.
