| Research Abstract |
In order to enable efficient numerical experiments that are necessary for research in geophysical fluid dynamics on relatively cheap computational platforms, a numerical library that provides a high performance on such platforms is developed. In particular, for subroutines that are used in the spherical spectral method, optimizations are done for GPGPU and SIMD functions (AVX instructions) on the newest CPUs. Furthermore, the developed numerical library is released on the Internet as a free software.
