Heterogeneous computing in a strongly-connected CPU-GPU environment: fast multiple time-evolution equation-based modeling accelerated using data-driven approach
Tsuyoshi Ichimura, Kohei Fujita, Muneo Hori +5
We propose a CPU-GPU heterogeneous computing method for solving time-evolution partial differential equation problems many times with guaranteed accuracy, in short time-to-solution…
Development of an Estimation Method for the Seismic Motion Reproducibility of a Three-dimensional Ground Structure Model by combining Surface-observed Seismic Motion and Three-dimensional Seismic Motion Analysis
Tsuyoshi Ichimura, Kohei Fujita, Ryota Kusakabe +3
The ground structure can substantially influence seismic ground motion underscoring the need to develop a ground structure model with sufficient reliability in terms of ground moti…
Low-ordered Orthogonal Voxel Finite Element with INT8 Tensor Cores for GPU-based Explicit Elastic Wave Propagation Analysis
Tsuyoshi Ichimura, Kohei Fujita, Muneo Hori +1
Faster explicit elastic wavefield simulations are required for large and complex three-dimensional media using a structured finite element method. Such wavefield simulations are su…
Implicit Low-Order Unstructured Finite-Element Multiple Simulation Enhanced by Dense Computation using OpenACC
Takuma Yamaguchi, Kohei Fujita, Tsuyoshi Ichimura +3
In this paper, we develop a low-order three-dimensional finite-element solver for fast multiple-case crust deformation analysis on GPU-based systems. Based on a high-performance so…
