Comparison of Acceleration Methods in a Radiation Transport Code With Adaptive Mesh Refinement

N-Body Code with Adaptive Mesh Refinement

We have developed a simulation code with the techniques which enhance both spatial and time resolution of the PM method for which the spatial resolution is restricted by the spacing of structured mesh. The adaptive mesh refinement (AMR) technique subdivides the cells which satisfy the refinement criterion recursively. The hierarchical meshes are maintained by the special data structure and are ...

Radiation Transport in Adaptive Mesh Refinement : Methodology and Application

Optimization and Evaluation of a Titanium Adaptive Mesh Refinement Code

Adaptive Mesh Refinement (AMR) is a grid-based approach to approximating the solutions to partial differential equations (PDEs). It is governed by the principle that some portions of the grid require more computation to solve than other regions. AMR uses an adaptive approach to adjust the resolution of the computational domain to reflect the varying computational needs. A highperformance implem...

Ram: a Relativistic Adaptive Mesh Refinement Hydrodynamics Code

We have developed a new computer code, RAM, to solve the conservative equations of special relativistic hydrodynamics (SRHD) using adaptive mesh refinement (AMR) on parallel computers. We have implemented a characteristic-wise, finite difference, weighted essentially non-oscillatory (WENO) scheme using the full characteristic decomposition of the SRHD equations to achieve fifth order accuracy i...

GAMER: a GPU-Accelerated Adaptive Mesh Refinement Code for Astrophysics

We present the newly developed code, GAMER (GPU-accelerated Adaptive MEsh Refinement code), which has adopted a novel approach to improve the performance of adaptive mesh refinement (AMR) astrophysical simulations by a large factor with the use of the graphic processing unit (GPU). The AMR implementation is based on a hierarchy of grid patches with an oct-tree data structure. We adopt a three-d...
