  • Cost-Age-Time Data Organized Garbage Collection

    Creator:
    Lee, Dongjun
    Abstract:
    NAND flash based solid state drives (SSDs) require out-of-place updating due to the characteristics of flash memories. In addition, due to the mismatched granularity between read/write and erase operations, a cleaning policy involving garbage collection and wear leveling has to perform data migration incurring high overhead. Another challenge is that...

  • 802.11 Channel Switching for High-Definition Video Streaming

    Creator:
    Sullivan, Erin
    Abstract:
    As screen resolution and video decoding capability have increased, high-definition (HD) video in resolutions as high as 1920 x 1080 is rapidly becoming the standard. Ad-hoc streaming of HD video over 802.11 wireless networks, e.g., streaming from a mobile device to a television, is convenient for users, but is hampered...

  • Flexible dual TCP/UDP streaming for H.264 HD video over WLANs

    Creator:
    Zhao, Jing
    Abstract:
    High Definition video streaming over WLANs faces many challenges because video data requires not only data integrity but also frames have strict playout deadline. Traditional streaming methods that rely solely on either UDP or TCP have difficulties meeting both requirements because UDP incurs packet loss while TCP incurs delay. This...

  • Program allocation for hypercube based dataflow systems

    Creator:
    Freytag, Vincent R.
    Abstract:
    The dataflow model of computation differs from the traditional control-flow model of computation in that it does not utilize a program counter to sequence instructions in a program. Instead, the execution of instructions is based solely on the availability of their operands. Thus, an instruction is executed in a dataflow...

  • Allocation of SISAL program graphs to processors using BLAS

    Creator:
    Raisinghani, Manoj H.
    Abstract:
    There are a number of well known techniques for extracting parallelism from a given program. They range from hardware implementations, building restructuring compilers or reorganizing of programs so as to specify all the available parallelism. The success rate of any of the known techniques is rather poor over all types...

  • Fine-grain parallelism on sequential processors

    Creator:
    Kotikalapoodi, Sridhar V.
    Abstract:
    There seems to be a consensus that future Massively Parallel Architectures will consist of a number nodes, or processors, interconnected by high-speed network. Using a von Neumann style of processing within the node of a multiprocessor system has its performance limited by the constraints imposed by the control-flow execution model....

  • Interface design and system impact analysis of a message-handling processor for fine-grain multithreading

    Creator:
    Metz, David
    Abstract:
    There appears to be a broad agreement that high-performance computers of the future will be Massively Parallel Architectures (MPAs), where all processors are interconnected by a high-speed network. One of the major problems with MPAs is the latency observed for remote operations. One technique to hide this latency is multithreading....

  • Simulation studies of routing algorithms for multicomputer systems

    Creator:
    Choi, Jangmin
    Abstract:
    Efficient routing of messages is critical to the performance of multicomputers. Many adaptive routing algorithms have been proposed to improve the network efficiency; however, they can make only short-sighted decisions to choose a channel for message routing because of limited information about network condition. The short-sighted decisions may cause unnecessary...

  • Network monitoring with focus on HTTP

    Creator:
    Schmid, Andreas
    Abstract:
    Since its introduction in the early 1990s, the quick growth of the World Wide Web (WWW) traffic raises the question of whether past Local Area Network (LAN) packet traces still reflect the current situation or whether they have become obsolete. For this thesis, several LAN packet traces were obtained by...

  • The architecture of a multimedia multiprocessor

    Creator:
    Choi, Keung-Sik
    Abstract:
    The multimedia capabilities of computers have recently become the focus of computer developers due to the increasing demand for advanced computer graphics and new media capabilities, such as video conferencing, 3-D visualization, and animation. To support these multimedia capabilities, specialized graphics hardware, such as MPEG encoding/decoding card, 3-D graphics card,...
