    PATPro: Power Aware Thin Provisioning of Resources in Virtualized Servers

    In traditional virtualization systems Virtual Machines (VMs) are usually over-provisioned for guarantying peak performance of hosting applications and thus waste a lot of computing resources. Although virtual machine consolidation can save power consumptions, it also increases the power intensity in a rack and makes the servers more prone to failures....

    Evaluating Data Storage Structures of MapReduce

    MapReduce framework and its open-source implementation Hadoop, a scalable and fault-tolerant infrastructure for big data analysis on large clusters, can achieve different performance with different data storage structures. This paper evaluates the performance about three kinds of data storage structures of MapReduce, namely row-store, column-store, and RCFile. The evaluating experiments...

    Robust Dynamic Bandwidth Allocation Method for Virtual Networks

    Multiple virtual networks sharing an underlying substrate network is considered a promising tool to diversify and reshape the future inter-networking paradigm. As a simple and straightforward approach, the static bandwidth allocation in Virtual Networks (VNs) can often be inefficient in practice, and the adaptive allocation scheme with a small time-scale...

    Variational Harmonic Method for Parameterization of Computational Domain in 2D Isogeometric Analysis

    In isogeometric anlaysis, parameterization of computational domain has great effects as mesh generation in finite element analysis. In this paper, based on the concept of harmonic map from the computational domain to parametric domain, a variational approach is proposed to construct the parameterization of computational domain for 2D isogeometric analysis....

    SALSA: Strategyproof Online Spectrum Admissions for Wireless Networks

    It is imperative to design efficient and effective online spectrum allocation methods since requests for spectrums often come in an online fashion. In this paper, the authors propose SALSA, StrAtegyproof onLing Splectrum Admission for wireless networks. They assume that the requests arrival follows the Poisson distribution. Upon receiving an online...
