  1. 16. Performance Optimisation of Discrete-Event Simulation Software on Multi-Core Computers

    Master-uppsats, KTH/Skolan för datavetenskap och kommunikation (CSC)

    Författare :Alain E. Kaeslin; [2016]
    Nyckelord :cache hierarchy; caches; communication overhead; data structures; discrete-event simulation; heap memory; linear speedup; logistic support; low-overhead profiler; memory allocator; microarchitecture; microarchitecture analysis; multi-core; optimisation; parallel execution; profiler; runtime; scalability; scalability bottlenecks; scalable memory allocator; simulation; translation lookaside buffer; translation lookaside buffer thrashing; TLB;

    Sammanfattning : SIMLOX is a discrete-event simulation software developed by Systecon AB for analysing logistic support solution scenarios. To cope with ever larger problems, SIMLOX's simulation engine was recently enhanced with a parallel execution mechanism in order to take advantage of multi-core processors. LÄS MER

  3. 17. Flying Penguins : Building and Evaluating the Viability of a Linux-based Drone

    Kandidat-uppsats, Blekinge Tekniska Högskola/Institutionen för datalogi och datorsystemteknik

    Författare :Anders Mårtensson; [2016]
    Nyckelord :drone; quadcopter; quadrocopter; multicopter;

    Sammanfattning : Traditional quadcopter flight controllers use microcontrollers to run the code that keeps the drone in the air, and when more processing power or versatility is needed the same microcontrollers are used in tandem with Linux-based single-board computers. It would be cheaper and reduce complexity if the single-board computer could entirely replace the microcontrollers. LÄS MER

  4. 18. Ranking Highscores : Evaluation of a dynamic Bucket with Global Query algorithm

    Kandidat-uppsats, Umeå universitet/Institutionen för datavetenskap

    Författare :Carl-Evert Kangas; [2016]
    Nyckelord :;

    Sammanfattning : The task of ranking highscores in a computer game may sound like a trivial task. It turns out it is not, because the naive solution have a time complexity not suitable for online applications in terms of response time and running cost. LÄS MER

  5. 19. Multicore mixed-criticality with a hierarchical real-time scheduler and resource servers

    Master-uppsats, Uppsala universitet/Institutionen för informationsteknologi

    Författare :Emanuel Berg; [2015]
    Nyckelord :;

    Sammanfattning : This is a real-time mixed-criticality system on a dual-core Linux desktop. The hardware/software architecture employs memory throttling so that modules can be isolated in execution as well as in analysis/certification. There are two asymmetrically dedicated cores. LÄS MER

  7. 20. Inversion of 2D Magnetotelluric and Radiomagnetotelluric data with Non-Linear Conjugate Gradient techniques

    Master-uppsats, Uppsala universitet/Geofysik

    Författare :Dominik Zbinden; [2015]
    Nyckelord :Numerical solutions; inverse theory; non-linear conjugate gradients; preconditioning; electromagnetic theory; magnetotellurics;

    Sammanfattning : I implemented and tested the method of Non-Linear Conjugate Gradients (NLCG) to invert magnetotelluric (MT) and radiomagnetotelluric (RMT) data in two dimensions. The forward problem and the objective function gradients were computed using finite-difference methods. LÄS MER
