  1. 16. Autonomic Management of Partitioners for SAMR Grid Hierarchies

    Författare :Henrik Johansson; Jarmo Rantakokko; Michael Thuné; Johan Steensland; Manish Parashar; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Beräkningsvetenskap; Scientific Computing;

    Sammanfattning : Parallel structured adaptive mesh refinement methods decrease the execution time and memory usage of partial differential equation solvers by adaptively assigning computational resources to regions with large solution errors. These methods result in a dynamic grid hierarchy. LÄS MER

  3. 17. Efficient Methods for Direct Volume Rendering of Large Data Sets

    Sammanfattning : Direct Volume Rendering (DVR) is a technique for creating images directly from a representation of a function defined over a three-dimensional domain. The technique has many application fields, such as scientific visualization and medical imaging. LÄS MER

  4. 18. Efficient and Reliable Simulation of Quantum Molecular Dynamics

    Författare :Katharina Kormann; Sverker Holmgren; Gunilla Kreiss; Hans O. Karlsson; Christian Lubich; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; time-dependent Schrödinger equation; quantum optimal control; exponential integrators; spectral elements; radial basis functions; global error control and adaptivity; high-performance computing implementation; Beräkningsvetenskap med inriktning mot numerisk analys; Scientific Computing with specialization in Numerical Analysis;

    Sammanfattning : The time-dependent Schrödinger equation (TDSE) models the quantum nature of molecular processes.  Numerical simulations based on the TDSE help in understanding and predicting the outcome of chemical reactions. LÄS MER

  5. 19. Performance Analysis and Optimization via Simulation

    Författare :Anders Svensson; Institutionen för informatik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; simulation; performance analysis; load sharing; mathematical model formalism; real-time control; design; Telecommunication engineering; modular optimization; circuit switched networks; Telekommunikationsteknik;

    Sammanfattning : A large amount of scientific work has been carried out to enhance the methods used for design and control of technical systems. For many of these systems, the main objective is to utilize the limited resources in an optimal way. Different simulation techniques have, in many cases, been successfully applied to the analysis.

  7. 20. Enhancing the Performance of Distributed Real-time Systems

    Författare :Hoai Hoang; Magnus Jonsson; Bertil Svensson; Luís Almeida; Högskolan i Halmstad; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Switched Ethernet; Real-Time Communication; EDF scheduling; Reducation of delay and jitter; Computer science; Datalogi;

    Sammanfattning : Advanced embedded systems can consist of many sensors, actuators and processors that are deployed on one or several boards, while having a demand of interacting with each other and sharing resources. Communication between different components usually has strict timing constraints. LÄS MER
