Hybrid Numerical Solvers for Massively Parallel Eigenvalue Computation and Their Benchmark with Electronic Structure Calculations
Hiroto Imachi, Takeo Hoshi
Optimally hybrid numerical solvers were constructed for massively parallel generalized eigenvalue problem (GEP).The strong scaling benchmark was carried out on the K computer and o…

Efficient numerical solver for first-principles transport calculation based on real-space finite-difference method
Shigeru Iwase, Takeo Hoshi, Tomoya Ono
We propose an efficient procedure to obtain Green's functions by combining the shifted conjugate orthogonal conjugate gradient (shifted COCG) method with the nonequilibrium Green's…
