Directionally Unsplit Hydrodynamic Schemes with Hybrid MPI/OpenMP/GPU Parallelization in AMR
Hsi-Yu Schive, Ui-Han Zhang, Tzihong Chiueh
We present the implementation and performance of a class of directionally unsplit Riemann-solver-based hydrodynamic schemes on Graphic Processing Units (GPU). These schemes, includ…
GAMER with out-of-core computation
Hsi-Yu Schive, Yu-Chih Tsai, Tzihong Chiueh
GAMER is a GPU-accelerated Adaptive-MEsh-Refinement code for astrophysical simulations. In this work, two further extensions of the code are reported. First, we have implemented th…
GAMER: a GPU-Accelerated Adaptive Mesh Refinement Code for Astrophysics
Hsi-Yu Schive, Yu-Chih Tsai, Tzihong Chiueh
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 refinemen…
AMiBA: System Performance
Kai-Yang Lin, Chao-Te Li, Paul T. P. Ho +29
The Y.T. Lee Array for Microwave Background Anisotropy (AMiBA) started scientific operation in early 2007. This work describes the optimization of the system performance for the me…
