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…
A New Subspace Iteration Algorithm for Solving Generalized Eigenvalue Problems
Biyi Wang, Hengbin An, Hehu Xie +1
It is needed to solve generalized eigenvalue problems (GEP) in many applications, such as the numerical simulation of vibration analysis, quantum mechanics, electronic structure, e…
JArena: Partitioned Shared Memory for NUMA-awareness in Multi-threaded Scientific Applications
Zhang Yang, Aiqing Zhang, Zeyao Mo
The distributed shared memory (DSM) architecture is widely used in today's computer design to mitigate the ever-widening processing-memory gap, and inevitably exhibits non-uniform…
JSweep: A Patch-centric Data-driven Approach for Parallel Sweeps on Large-scale Meshes
Jie Yan, Zhang Yang, Aiqing Zhang +1
In mesh-based numerical simulations, sweep is an important computation pattern. During sweeping a mesh, computations on cells are strictly ordered by data dependencies in given dir…
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…
Parallel 3-dim fast Fourier transforms with load balancing of the plane waves
Xingyu Gao, Zeyao Mo, Jun Fang +1
The plane wave method is most widely used for solving the Kohn-Sham equations in first-principles materials science computations. In this procedure, the three-dimensional (3-dim) t…
Cluster Identification and Characterization of Physical Fields
Guangcai Zhang, Aiguo Xu, Guo Lu +1
The description of complex configuration is a difficult issue. We present a powerful technique for cluster identification and characterization. The scheme is designed to treat with…
