    A Generic Tool Supporting Cache Design and Optimisation on Shared Memory Systems
    (9th workshop on parallel systems and algorithms – workshop of the GI/ITG special interest groups PARS and PARVA, 2008) Schindewolf, Martin; Tao, Jie; Karl, Wolfgang; Cintra, Marcelo
    For multi-core architectures, improving the cache performance is crucial for the overall system performance. In contrast to the common approach to design caches with the best trade-off between performance and costs, this work favours an application specific cache design. Therefore, an analysis tool capable of exhibiting the reason of cache misses has been developed. The results of the analysis can be used by system developers to improve cache architectures or can help programmers to improve the data locality behaviour of their programs. The SPLASH-2 benchmark suite is used to demonstrate the abilities of the analysis model.

    Grid Virtualization Engine: Providing Virtual Resources for Grid Infrastructure
    (9th workshop on parallel systems and algorithms – workshop of the GI/ITG special interest groups PARS and PARVA, 2008) Kwemou, Emeric; Wang, Lizhe; Tao, Jie; Kunze, Marcel; Kramer, David; Karl, Wolfgang
    Virtual machines offer a lot of advantage such as easy configuration and management and can simplify the development and the deployment of Grid infrastructures. Various virtualization implementations despite have similar functions often provide different management and access interfaces. The heterogeneous virtualization technologies bring challenges for employing virtual machine as computing resources to build Grid infrastructures. The work proposed in this paper focus on a Web service based virtual machine provider for Grid infrastructures. The Grid Virtualization Engine (GVE) creates an abstraction layer between users and underlying virtualization technologies. The GVE implements a scalable distributed architecture, where an GVE Agent represents a computing center. The Agent talks with different virtualization product inside the computing center and provides virtual machine resources to GVE Site Service. Users could require computing resources through GVE Site Services. The system is designed and implemented in the state of the arts of distributed computing: Web service and Grid standards.

    On the cache access behavior of openMP applications
    (ARCS 2004 – Organic and pervasive computing, 2004) Tao, Jie; Karl, Wolfgang
    The widening gap between memory and processor speed results in increasing requirements to improve the cache utility. This issue is especially critical for OpenMP execution which usually explores fine-grained parallelism. The work presented in this paper studies the cache behavior of OpenMP applications in order to detect potential optimizations with respect to cache locality. This study is based on a simulation environment that models the parallel execution of OpenMP programs and provides comprehensive information about the runtime data accesses. This performance data enables a detailed analysis and an easy understanding of the cache operations performed on-line during the execution.
