In this study, we developed matrix solvers which are applicable to a wide range of computer physics applications, such as electronic structure calculation, plasma simulation and crack growth simulation. Our main targets are direct solvers for sparse and band matrices and generalized eigenvalue solvers for dense matrices. With the use of communication-avoiding algorithms and automatic code selection techniques, our solvers aim at achieving high strong-scaling performance. We applied our solvers to time-dependent simulation of organic polymeric materials and crack growth simulation and verified their performance.
