英文摘要
The present study purposed to perform the low-frequency fast-multipole integral equation method for three dimensional Helmholtz' equation efficiently on a graphical processing unit(GPU), which is regarded as a multi-threaded many-core processor. Focusing on the multipole-to-local(M2L) operation that is the most time-consuming in the whole computation, we proposed high-performance algorithms that can decrease the memory-to-flop ratio in the operation and implemented a computer programme optimised for NVIDIA's Fermi GPUs. In the numerical analysis, we verified the improvement in computational performance and successfully performed an acoustic scattering problem of 560 million degree of freedom in 2. 8 hours.
