  2. 16. Acceleration of Compressible Flow Simulations with Edge Using  Implicit Time Stepping

    Author : Evelyn Otero; Arthur Rizzi; Richard P. Dwight; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Compressible CFD; Convergence Acceleration; Implicit Time-Stepping; LU-SGS; Upwind Type Dissipation; Line-implicit; Ordering; Parallelization; Parameters; Multigrid;

    Abstract : Computational fluid dynamics (CFD) is a significant tool routinely used indesign and optimization in aerospace industry. Often cases with unsteadyflows must be computed, and the long compute times of standard methods hasmotivated the present work on new implicit methods to replace the standardexplicit schemes.

  4. 17. Automatic Parallelization of Simulation Code from Equation Based Simulation Languages

    Author : Peter Aronsson; Peter Fritzson; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; state-of-the-art equation; object oriented modeling; automatic parallelization tool; data dependency graph; clustering algorithms; Computer science; Datavetenskap;

    Abstract : Modern state-of-the-art equation based object oriented modeling languages such as Modelica have enabled easy modeling of large and complex physical systems. When such complex models are to be simulated, simulation tools typically perform a number of optimizations on the underlying set of equations in the modeled system, with the goal of gaining better simulation performance by decreasing the equation system size and complexity.

  5. 18. Early Vision Optimization: Parametric Models, Parallelization and Curvature

    Author : Petter Strandmark; Matematik LTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : Early vision is the process occurring before any semantic interpretation of an image takes place. Motion estimation, object segmentation and detection are all parts of early vision, but recognition is not. READ MORE

  6. 19. Parallelization of stochastic estimation algorithms on multicore computational platforms

    Author : Olov Rosén; Alexander Medvedev; Uppsala universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Elektroteknik med inriktning mot reglerteknik; Electrical Engineering with specialization in Automatic Control;

    Abstract : The main part of this licentiate thesis concerns parallelization of recursive estimation methods, both linear and nonlinear. Recursive estimation deals with the problem of extracting information about parameters or states of a dynamical system, given noisy measurements of the system output and plays a central role in many applications of signal processing, system identification, and automatic control.

  7. 20. Automatic and Explicit Parallelization Approaches for Mathematical Simulation Models

    Author : Mahder Gebremedhin; Peter Fritzson; Francesco Casella; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Simulation; Modelling; Parallel Programming; Mutli-core; Modelcia; OpenModelica; ParModelica;

    Abstract : The move from single core and processor systems to multi-core and many-processors systemscomes with the requirement of implementing computations in a way that can utilizethese multiple units eciently. This task of writing ecient multi-threaded algorithmswill not be possible with out improving programming languages and compilers to providethe mechanisms to do so. READ MORE
