Implementing Performance Portability of High Performance Computing Programs in the New Golden Age of Chip Architecture
Weifeng Liu, Linping Wu, Xiaowen Xu +1
As an important goal of high-performance computing, the concept of performance portability has been around for many years. As the failure of Moore's Law, it is no longer feasible t…
AutoAMG(): An Auto-tuned AMG Method Based on Deep Learning for Strong Threshold
Haifeng Zou, Xiaowen Xu, Chen-Song Zhang +1
Algebraic Multigrid (AMG) is one of the most used iterative algorithms for solving large sparse linear equations . In AMG, the coarse grid is a key component that affects the…
Convergence estimation and characteristic analysis of a two-level iterative algorithm for the discretized three-temperature energy linear systems
Yue Hao, Silu Huang, Xiaowen Xu
For solving the discretized three-temperature energy linear systems, Xu et al. proposed a physical-variable based coarsening two-level iterative method (PCTL algorithm) in 2009 and…
Algebraic multigrid block preconditioning for multi-group radiation diffusion equations
Xiaoqiang Yue, Shulei Zhang, Xiaowen Xu +2
The paper focuses on developing and studying efficient block preconditioners based on classical algebraic multigrid for the large-scale sparse linear systems arising from the fully…
Parallel-in-Time with Fully Finite Element Multigrid for 2-D Space-fractional Diffusion Equations
Xiaoqiang Yue, Shi Shu, Xiaowen Xu +2
The paper investigates a non-intrusive parallel time integration with multigrid for space-fractional diffusion equations in two spatial dimensions. We firstly obtain a fully discre…
Information Splitting for Big Data Analytics
Shengxin Zhu, Tongxiang Gu, Xiaowen Xu +1
Many statistical models require an estimation of unknown (co)-variance parameter(s) in a model. The estimation usually obtained by maximizing a log-likelihood which involves log de…
