| Outline of Final Research Achievements |
For practical use of ultra-large-scale finite element analysis, a heterogenous distributed-memory parallel iterative algorithm based on the domain decomposition method has been studied. In particular, an optimization implementation of the DDM on the GPGPU and a many-core processor, a Scaled-BDD method for multiple-material model, and a MINRES-like_CS method for solving complex symmetric linear systems arising from electromagnetic analysis have been developed. As the result, a high-frequency electromagnetic field analysis with tens of billions degrees of freedom model has been successfully solved within a practical time limit.
