This paper explores the relation between the structured parallelism exposed by the decomposable BSP (D-BSP) model through submachine locality and locality of reference in multi-level cache hierarchies. Specifically, an efficient cache-oblivious algorithm is developed to simulate D-BSP programs on the ideal cache model (ICM). The effectiveness of the simulation is proved by showing that optimal cache-oblivious algorithms for prominent problems can be obtained from D-BSP algorithms. Finally, a tight relation between optimality in the D-BSP and ICM models is established
