摘要：
A blockwise approach to parallel structured adaptive mesh refinement is considered. The initial, coarse grid is divided into n(1) x n(2) blocks. Subsequent refinements are carried out with respect to entire blocks. The paper addresses the issue of choosing n(1) and n(2) optimally. A theoretical model for the execution time is formulated. Subsequently, it is suggested how to minimize the execution time with respect to the number of blocks. The approach is validated for test cases, where it successfully predicts the optimal choice of granularity. Finally, it is discussed how this can be automatized and integrated into the SAMR code.
