| Research Abstract |
New linear solvers, eigenvalue solvers and modified algorithms that realize to compute fast with high accuracy and stability were proposed. These were developed to solve large-scale numerical simulations, such as electromagnetic problems, computational quantum chemistry problems and computational fluid dynamics problems. Further, in order to support large-scale numerical simulations, new technologies and libraries such as auto-tuning technologies to decide data structure depending on application problems' characteristics, job scheduling strategies to assign optimal computational resources and free library for arbitrary/higher precision linear algebra were developed.
