Outline of Final Research Achievements

In the present study, we successfully developed the new shape function for meshless approaches, and successfully developed the new iterative solver based on next generation distributed processing architectures such as graphics processing unit (GPU) and Many Integrated Core (MIC) for linear systems obtained by meshless approaches. The numerical results indicate that the numerical instability of the new method with the new shape functions is drastically increased. In addition, we developed Krylov subspace method with communication avoiding technique, and the numerical features are investigated.
