Outline of Final Research Achievements

The purpose of this study is to develop a fast meshless analysis system based on an implicit function. To this end, an implicit function that can execute fast evaluation of function values has been developed. Computation time for generating the implicit function is about 12.7 times faster than that of conventional one based on the B-Spline. In addition, to solve linear systems obtained by meshless methods, a parallel algorithm for iterative methods on many integrated core (MIC) architectures has been developed, and the computation time for solving the linear system using the parallel algorithm is about 3 times faster than that of serial execution on CPU. Furthermore, parallel algorithms of electromagnetic wave propagation simulations using meshless time-domain method (MTDM) on GPU/MIC have been developed. By using the parallel algorithms, the computation times of the simulation on GPU and MIC are about 8.3 and 8.16 times faster than those of serial execution on CPU, respectively.
