| Outline of Final Research Achievements |
In this research project, we focused on the complex moment-based eigensolvers, which are massively parallel eigenvalue analysis methods originated in Japan and have been actively studied in recent years. We developed mathematical fault-tolerance techniques through theoretical error analysis of the method, aiming to realize fault-tolerance at the algorithm level. Theoretical and experimental evaluations have shown that the developed technology can obtain eigenpairs with high speed and accuracy even in the presence of failures. In addition, we have also developed technologies to improve usability for practical use. The results of this research project were presented at domestic and international conferences and submitted to international journals.
