To solve nonlinear eigenvalue problems such as those arising from Kohn-Sham electronic structure calculations, a SCF (self-consistent field) eigensolver has a structure of three or more loops. Convergence analysis of such an SCF-eigensolver remains a largely open problem. In this talk, we focus on the convergence analysis of the innermost loop of the SCF-eigensolver. The innermost loop involves solving linear systems of equations and typically consumes most of the total runtime. We propose a scheme to detect the stagnation of the innermost iteration and apply it to improve the computational efficiency of the SCF-eigensolver.
