数値解析・応用解析セミナー

4月22日(木) 15:30 -- 17:00  Yu-Hsun Lee (京都大学情報学研究科)
            ``GPGPU computation of vortex filament evolution under
              the Biot-Savart law ''

＜研究発表要旨＞
In this talk, we investigate numerical reliability of self-induced
motion of vortex filaments by the Biot-Savart law which is represented
as an integro-differential. We use both quadruple precision arithmetic
and 50 decimal digits arithmetic to examine the reliability of schemes.
With the development of general-purpose computing on graphics processing
units (GPGPU), we are able to perform high-performance scientific
computing on GPUs. We accelerate computations by using GPU (Graphics
Processing Unit) under the double precision environment. The accelerated
computation enables us to estimate numerical properties with various
parameters, and therefore we establish a reliability criterion for
this model.
