Journal ArticleDOI
Neural networks in computational mechanics
Genki Yagawa,Hiroshi Okuda +1 more
TL;DR: The most outstanding characteristics of the neural network aided computation is that neither complicated programmings nor rigid algorithms are needed, and the network's inherent parallelism suits the massively parallel computer architectures.
Journal ArticleDOI

TL;DR: The frontier soft-material beamline at BL03XU for soft materials was recently installed at SPring-8, using an in-vacuum undulator.
Journal ArticleDOI
GPU Acceleration for FEM-Based Structural Analysis
TL;DR: This review investigates the adoption of GPUs as accelerators in the field of Finite Element Structural Analysis, a design tool that is now essential in many branches of engineering, and surveys the work that has been done in accelerating the most time consuming steps of the analysis.
Journal ArticleDOI

TL;DR: In this paper, a new experimental system has been launched by coupling with the measurement techniques, which are grazing incidence small/wide-angle X-ray Scattering (GISWAXS) and grazing incidence Xray diffraction (GIXD), at the BL03XU of SPring-8.
Journal ArticleDOI
Parallel Iterative Solvers with Localized ILU Preconditioning for Unstructured Grids on Workstation Clusters
Kengo Nakajima,Hiroshi Okuda +1 more
TL;DR: The localized ILU(O) preconditioning method is implemented in various types of iterative solvers and provides data locality and good parallelization on each processor.
