  1. 1. On Control and stabilisation of floating wind platforms with the help of CFD analysis and the Magnus effect

    University essay from KTH/Numerisk analys, NA

    Author : Georg Neumüller; [2017]
    Keywords : ;

    Abstract : With new technologies and possibilities arising both in the renewable energy sector as well as in the field of Computational Fluid Dynamics, this thesis describes the simulation of vortex- induced vibrations for floating wind turbine platforms. The aim is to control and stabilize floating wind platforms with the help of CFD and the Magnus effect. READ MORE

  3. 2. Efficient Implementation of 3D Finite Difference Schemes on Recent Processor Architectures

    University essay from KTH/Skolan för datavetenskap och kommunikation (CSC)

    Author : Frederick Ceder; [2015]
    Keywords : hpc; high performance computing; intel; haswell; xeon phi; knights corner; burgers equation; finite difference methods; fdm; ftcs; parallel programming; vectorization; simd;

    Abstract : Efficient Implementation of 3D Finite Difference Schemes on Recent Processors Abstract In this paper a solver is introduced that solves a problem set modelled by the Burgers equation using the finite difference method: forward in time and central in space. The solver is parallelized and optimized for Intel Xeon Phi 7120P as well as Intel Xeon E5-2699v3 processors to investigate differences in terms of performance between the two architectures.

  4. 3. Conversion of Cray pointers to Fortran 90 pointers in a Ray tracing application

    University essay from Institutionen för datavetenskap, fysik och matematik, DFM

    Author : Farrukh Mateen; Syed Nawazuddin; [2013]
    Keywords : ;

    Abstract : This report is a documentation of techniques involved in the conversion of Cray pointers to Fortran 90 pointers in a ray-tracing application. A CAD object is generated and used for ray-tracing and the output is rendered on a pixel screen. Several implementations of ray-tracing were compared. READ MORE

  5. 4. Large Scale Modelling of Striatal Network

    University essay from KTH/Matematik (Inst.)

    Author : Muhammad Shahid Bilal; [2012]
    Keywords : ;

    Abstract : Numerical simulations play an important role to uncover the dynamic behaviour at the cellular and network levels and accelerate the work in the field of Neuroscience. The modern computational technologies have made it possible to simulate a huge network of neurons which was possible only in theory two decades ago. READ MORE

  6. 5. High-Level Parallel Programming of Computation-Intensive Algorithms on Fine-Grained Architecture

    University essay from Sektionen för Informationsvetenskap, Data– och Elektroteknik (IDE)

    Author : Fahad Islam Cheema; [2009]
    Keywords : Parallel computing; FPGA; Mitrion; Computation-intensive; HDL; Mitrionics; Mitrion C; Fine grained; Interpolation Kernels; High level programming; Embedded Systems; Accelerator; HPC; Supercomputing; Cray; XD1;

    Abstract : Computation-intensive algorithms require a high level of parallelism and programmability, which make them good candidate for hardware acceleration using fine-grained processor arrays. Using Hardware Description Language (HDL), it is very difficult to design and manage fine-grained processing units and therefore High-Level Language (HLL) is a preferred alternative. READ MORE
