  1. 1. Understanding Multicore Performance : Efficient Memory System Modeling and Simulation

    Författare :Andreas Sandberg; Erik Hagersten; David Black-Schaffer; David A. Wood; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Computer Architecture; Simulation; Modeling; Sampling; Caches; Memory Systems; gem5; Parallel Simulation; Virtualization; Sampling; Multicore; Datavetenskap; Computer Science;

    Sammanfattning : To increase performance, modern processors employ complex techniques such as out-of-order pipelines and deep cache hierarchies. While the increasing complexity has paid off in performance, it has become harder to accurately predict the effects of hardware/software optimizations in such systems. LÄS MER

  3. 2. Performance Modeling of Multi-core Systems : Caches and Locks

    Författare :Xiaoyue Pan; Bengt Jonsson; David Whalley; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; performance modeling; performance analysis; multi-core; cache; lock;

    Sammanfattning : Performance is an important aspect of computer systems since it directly affects user experience. One way to analyze and predict performance is via performance modeling. In recent years, multi-core systems have made processors more powerful while keeping power consumption relatively low. LÄS MER

  4. 3. Four Proposals for Enterprise Modeling

    Författare :Darek Eriksson; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; change; development; enterprise; modeling process; enterprise modeling language; systems science; constructivist epistemology; organization; modeling; multi-modal modeling; model;

    Sammanfattning : Any enterprise whether a major corporation, a small family-owned business, a public school, a hospital, or a military unit needs to develop itself continuously in order to adapt to the challenges originating within itself and from its environment, in relation to its overall purpose or mission. Deliberate development and management of an enterprise manifest complexity that gives rise to a central challenge: how can we obtain a comprehensive intelligibility of an enterprise? One conceptual tool to overcome this challenge is enterprise modeling; it supports articulation of an enterprise and consequently intelligibility of its complexity. LÄS MER

  5. 4. Efficient Memory Modeling During Simulation and Native Execution

    Författare :Nikos Nikoleris; Erik Hagersten; Lieven Eeckhout; Uppsala universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; performance analysis; cache performance; multicore performance; memory system; memory bandwidth; memory contention; performance prediction; multi-threading; multiprocessing systems; program diagnostics; commodity multicores; multithreaded program resource requirements; performance counters; scalability bottleneck; scalability improvement; Computer Science; Datavetenskap;

    Sammanfattning : Application performance on computer processors depends on a number of complex architectural and microarchitectural design decisions. Consequently, computer architects rely on performance modeling to improve future processors without building prototypes. LÄS MER

  7. 5. Configuration Design of a High Performance and Responsive Manufacturing System : Modeling and Evaluation

    Författare :Daniel Tesfamariam Semere; Bengt Lindberg; Bolmsjö Gunnar; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Configuration; Modeling; Evaluation; Manufacturing engineering; Produktionsteknik;

    Sammanfattning : Configuring and reconfiguring a manufacturing system is presented as an issue with increasing importance due to higher frequency of system configuration or major reconfigurations to accommodate new set of requirements and/or the need to configure the system to make it usable across generations of products or product families. This research has focused in the modeling, evaluation and selection decisions which involves multiple, incommensurate and conflicting objectives. LÄS MER
