    A kind of hidden terminal problem, called the POINT problem, which is caused by the expansion of the interference range of the receiver due to the controlled transmission power of the sender, is deemed a notorious problem in wireless ad hoc networks. This paper utilizes physical and virtual carrier-sensing schemes to avoid the POINT problem. We analyze the relationships among the transmission rang... View full abstract»

    We consider static ad hoc wireless networks whose nodes, equipped with the same initial battery charge, may dynamically change their transmission range. When a node v transmits with range r(v), its battery charge is decreased by β r(v)2, where β > 0 is a fixed constant. The goal is to provide a range assignment schedule that maximizes the number of broadcast operations ... View full abstract»

    Ethernet has been used for connecting hosts in PC clusters, besides its use in local area networks. Although a layer-2 Ethernet topology is limited to a tree structure because of the need to avoid broadcast storms and deadlocks of frames, various deadlock-free routing algorithms on topologies that include loops suitable for parallel processing can be employed by the application of IEEE 802.1Q VLAN...

    Grid applications often need to distribute large amounts of data efficiently from one cluster to multiple others (multicast). Existing sender-initiated methods arrange nodes in optimized tree structures, based on external network monitoring data. This dependence on monitoring data severely impacts both ease of deployment and adaptivity to dynamically changing network conditions. In this paper, we ... View full abstract»

    Today's data centers face two critical challenges. First, various customers need to be assured by meeting their required service-level agreements such as response time and throughput. Second, server power consumption must be controlled in order to avoid failures caused by power capacity overload or system overheating due to increasing high server density. However, existing work controls power and ... View full abstract»

    MPI collective I/O has been an effective method for parallel shared-file access and maintaining the canonical orders of structured data in files. Its implementation commonly uses a two-phase I/O strategy that partitions a file into disjoint file domains, assigns each domain to a unique process, redistributes the I/O data based on their locations in the domains, and has each process perform I/O for...

  • Achieving 100% Throughput in Input-Buffered WDM Optical Packet Interconnects

    Packet scheduling algorithms that deliver 100% throughput under various types of traffic enable an interconnect to achieve its full capacity. Although such algorithms have been proposed for electronic interconnects, they cannot be directly applied to WDM optical interconnects due to the following reasons. First, the optical counterpart of electronic random access memory (RAM) is absent; second, th... View full abstract»

  • Interlacing Bypass Rings to Torus Networks for More Efficient Networks

    We introduce a new technique for generating more efficient networks by systematically interlacing bypass rings to torus networks (iBT networks). The resulting network can improve the original torus network by reducing the network diameter, node-to-node distances, and by increasing the bisection width without increasing wiring and other engineering complexity. We present and analyze the statement t... View full abstract»

    The use of formal models of computation in dealing with increasing complexity of embedded systems design is gaining attention. A successful model of computation must be able to handle both control-dominated and data-dominated behaviors, which are most often simultaneously present in complex embedded systems. Besides behavioral heterogeneity, direct support for modeling distributed systems is also ... View full abstract»

    Unlike usual VLSI approaches necessary for the computation of intensive Low-Density Parity-Check (LDPC) code decoders, this paper presents flexible software-based LDPC decoders. Algorithms and data structures suitable for parallel computing are proposed in this paper to perform LDPC decoding on multicore architectures. To evaluate the efficiency of the proposed parallel algorithms, LDPC decoders w... View full abstract»

    Both power and performance are important concerns for enterprise data centers. While various management strategies have been developed to effectively reduce server power consumption by transitioning hardware components to lower power states, they cannot be directly applied to today's data centers that rely on virtualization technologies. Virtual machines running on the same physical server are cor... View full abstract»

    Convolution represents a major computational load for many scientific and engineering applications, including seismic surface simulations and seismic imaging. Since convolution presents a heavy computational load, increasing its efficiency can significantly enhance the performance of associated applications. In this work, we present an in-depth analysis of the convolution algorithm and its complex... View full abstract»
