Xiaomei Li · Jisuanji gongcheng · 2003
The computational characteristic of the third generation ocean general circulation model (OGCM) from the state key laboratory of numerical modeling for atmospheric science and geophysical fluid dynamics, institute of atmosphere physics (LASG/IAP) is investigated.The paper analyzes its parallelism and implementation both on distributed memory and shared memory parallel computer, with the spitting of latitude zones. Meanwhile, with a view to the main characteristics of high performance architecture, the optimization of parallel computing for OGCM is discussed. Several strategies of optimization are presented here, that are instructive to the optimization of parallel computing for the grand challenging problems.
