| Outline of Final Research Achievements |
In this project, we considered a numerical algorithm for nonlinear eigenvalue problems that can be applied to large-scale problems in various application areas of computational sciences. We studied theoretical aspects and some related techniques of a contour integral-based eivensolver for nonlinear eigenvalue problems to apply for various practical applications in computational sciences. According to the results, we developed a method for a spectral projection method using contour integral. We also developed some methods and related techniques to attain high performance and high reliability on large-scale cluster machines. We evaluated the efficiency of the method with some applications. We implemented our method on a function CISS in the software library for the solution of large scale sparse eigenvalue problems on parallel computers SLEPc that is developing at Universitat Politecnica de Valencia.
