| Abstract(in English) | In order to execute stencil calcurations of the large scale problems beyond physical memory, we evaluated three different implementations with the temporal blocking locality-aware algorithm that uses a flash storage as an expanded memory. We also proposed an asynchronous i/o (aio) technique tuned for flash storages by analyzing a situation of i/o. However, compared with other techniques, the execution time of the aio technique is long because of boundary restrictions. Then, we investigated the optimization of the aio technique, and the reduced execution time by 45% by allocating blocks in a continuation memory space, padding page between x-y plain memory areas, and inner loop transformation. |
