• Krylov Space Iterative Solvers on Graphics Processing Units

  Publikacja

  • A. Dziekoński
  • M. Mrozowski

  - Rok 2010

  CUDA architecture was introduced by Nvidia three years ago and since then there have been many promising publications demonstrating a huge potential of Graphics Processing Units (GPUs) in scientific computations. In this paper, we investigate the performance of iterative methods such as cg, minres, gmres, bicg that may be used to solve large sparse real and complex systems of equations arising in computational electromagnetics.

  • M. Słodkowski

  - CONCURRENCY AND COMPUTATION-PRACTICE & EXPERIENCE - Rok 2015

  This paper explores the possibilities of using a graphics processing unit for complex 3D finite difference computation via MUSTA‐FORCE and WENO algorithms. We propose a novel algorithm based on the new properties of CUDA surface memory optimized for 2D spatial locality and compare it with 3D stencil computations carried out via shared memory, which is currently considered to be the best approach. A case study was performed for...

• Shallow Water Equations as a Mathematical Model of Whitewater Course Hydrodynamics

  Publikacja

  • M. Szydłowski
  • P. Mikos-Studnicka

  - GeoPlanet: Earth and Planetary Sciences - Rok 2020

  Predicting the positions of local hydraulic phenomena, as well as accurately esti-mating the depth and velocity of the water flow are necessary to correctly config-ure a whitewater canoeing course. Currently, a laboratory and full 3D CFD model-ing are typically used in the design process to meet these needs. The article points to another possibility which can be useful at the preliminary stage of the design. The authors show that...

  - Rok 2023

  The modern maritime industry is moving toward the development of technology that will allow for full or partial autonomy of ship operation. This innovation places high demands on ship performance prediction techniques at the design stage. The researchwork presented in the article is related to the design stage of the ship and concerns methods for prognosis and evaluation of the specific operational condition of the ship, namely...

  - INTERNATIONAL JOURNAL OF MULTIPHASE FLOW - Rok 2021

  Significant effort has been exerted on developing fast and reliable numerical models for modeling particulate flow; this is challenging owing to the complexity of such flows. To achieve this, reliable and high-quality experimental data are required for model development and validation. This study presents the design of a novel test-rig that allows the visualization and measurement of particle flow patterns during the collision...

• Implementation of FDTD-Compatible Green's Function on Graphics Processing Unit

  Publikacja

  • T. Stefański
  • K. Krzyżanowska

  - IEEE Antennas and Wireless Propagation Letters - Rok 2012

  In this letter, implementation of the finite-difference time domain (FDTD)-compatible Green's function on a graphics processing unit (GPU) is presented. Recently, closed-form expression for this discrete Green's function (DGF) was derived, which facilitates its applications in the FDTD simulations of radiation and scattering problems. Unfortunately, implementation of the new DGF formula in software requires a multiple precision...
