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

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

    Abstract : 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. READ MORE

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

    Author : Nikos Nikoleris; Erik Hagersten; Lieven Eeckhout; Uppsala universitet; []
    Keywords : 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;

    Abstract : 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. READ MORE

  5. 3. Prior Knowledge and Recognition Memory : a Computational Modeling Approach

    Author : Johan Hellman; Institutionen för psykologi; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Recognition memory; Episodic memory; Pre-experimental familiarity; Event-Related Potentials; Item variability; Receiver-Operating Characteristics; Computational Models;

    Abstract : For more than a century, an immense interest has been devoted to the study of recognition memory, where a multitude of memory phenomena has been explained. Recognition memory is usually described with parsimonious measurement and statistical models, stemming from dual process theory and signal detection theory. READ MORE

  6. 4. Memory modeling and synthesis for real-time video processing systems

    Author : Benny Thörnberg; Mattias O´Nils; Bengt Oelmann; Erwin de Kock; Mittuniversitetet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; memory modeling; Electrical engineering; electronics and photonics; Elektroteknik; elektronik och fotonik;

    Abstract : In this thesis, a new design methodology and new tools for modeling and synthesis of real-time video processing systems are presented. A real-time video processing system is a system that performs computations on a continuous sequence of images. Image processing is a memory intensive application. READ MORE

  7. 5. Towards Low-Complexity Scalable Shared-Memory Architectures

    Author : Håkan Zeffer; Erik Hagersten; John Carter; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; shared memory; distributed shared memory; hardware-software trade-off; software coherence; coherence profiling; remote access cache; chip multiprocessor; simultaneous multi threading; simulation; workload characterization; statistical cache model; Computer engineering; Datorteknik;

    Abstract : Plentiful research has addressed low-complexity software-based shared-memory systems since the idea was first introduced more than two decades ago. However, software-coherent systems have not been very successful in the commercial marketplace. We believe there are two main reasons for this: lack of performance and/or lack of binary compatibility. READ MORE
