  2. 1. 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

  4. 2. Infinite Structures in Timed Systems

    Author : Pavel Krcal; Wang Yi; Joel Ouaknine; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Theoretical computer science; Teoretisk datalogi; Datalogi; Computing Science;

    Abstract : Real time systems distinguish themselves by explicitly stating timing constraints in the system specification. This requires specific methods and tools in system design to ensure such constraints. We focus on one of the methods applied in the validation phase, namely formal verification. READ MORE

  5. 3. Towards nanodosimetry: therapeutic radiation measurements using the variance method

    Author : Linda Eliasson; Ayse Nyberg; Torbjörn Bäck; Jan Lillhök; Anja Almén; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Atomic; Subatomic and Astrophysics; Atomär fysik; subatomär fysik och astrofysik;

    Abstract : Understanding how radiation damage occurs in human tissue seems to lie in the knowledge of energy depositions in DNA-size volumes, with diameters typically around a few nanometres. In such small volumes the energy transfers are stochastic and described using distributions of events along a particle track and relevant mean values. READ MORE

  6. 4. Characterization of Shared Resource Contention in Multi-core Systems

    Author : Jakob Danielsson; Mikael Sjödin; Stefano Di Carlo; Mälardalens högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Computer Science; datavetenskap;

    Abstract : Multi-core computers are infamous for being hard to use in time-critical systems due to execution-time variations as an effect of shared resource contention. In this thesis we study the problem of shared resource contention which occurs when multiple applications executing on different cores do not have exclusive ownership of a shared resource. READ MORE

  7. 5. Automatic Characterization and Mitigation of Shared-resource Contention in Multi-core Systems

    Author : Jakob Danielsson; Mikael Sjödin; Moris Behnam; Seceleanu Tiberiu; Marcus Jägemar; Håkan Grahn; Mälardalens universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Computer Science; datavetenskap;

    Abstract : Multi-core computers are infamous for being hard to use in time-critical systems due to execution-time variations as an effect of shared resource contention. In this thesis, we study the problem of shared resource contention, which occurs when multiple applications executing on different cores do not have exclusive access to of a shared hardware resource.
