Objectives

Our group develops a coupling tool ppOpen-MATH/MP for large-scale weak coupling simulations that enable multi-component coupling and large-scale data transfer/interpolation. ppOpen-MATH/MP has functions as follows: support of various grid systems, 2D and 3D coupling; coupling between real time simulation and ppOpen-VIS, and optimization of process mapping.

Numerical models such as atmospheric and ocean models generally have various types of grid systems, especially under the recent trend of the high-resolution modeling. Examples are two models developed at AORI, the University of Tokyo, in cooperation with other institutes; the atmospheric model NICAM (Nonhydrostatic Icosahedral Atmopheric Model) uses the icosahedral-geodesic grid, while the ocean model COCO (CCSR Ocean Component Model) uses the tri-polar grid. Toward the near future high-resolution earth system modeling, coupling of models with such a different structure is required. Our project aims to advance a coupling tool to be efficient and powerful for the post-exabyte era of super-computers. The future coupler will not only enable coupling between different components, but also require further functions such as I/O managements, process driver, and fault tolerance.
