SOLVERS FOR O(N) ELECTRONIC STRUCTURE IN THE STRONG SCALING LIMIT
收藏 引用
SIAM JOURNAL ON SCIENTIFIC COMPUTING 2016年 第1期38卷 C1-C21页
作者: Bock, Nicolas Challacombe, Matt Kale, Laxmikant V. Los Alamos Natl Lab Div Theoret Los Alamos NM 87544 USA Univ Illinois Dept Comp Sci Parallel Programming Lab Champaign IL 61801 USA
We present a hybrid OpenMP/Charm++ framework for solving the O(N) self-consistent-field eigenvalue problem with parallelism in the strong scaling regime, P >> N, where P is the number of cores, and N is a measur... 详细信息
