抄録（英）
10 peta-FLOPS supercomputer "K computer" will begin cooperation in this autumn, and investigation of exa-scale computing already has begun. The other hand, memory throughput will not be enough to supercomputing. So, we consider to using Last-Level-Cache(LLC) on the CPU chip efficiently. Generally, the unstructured CFD solver is parallelized by region decomposition with "Halo". Then, small region which can be computed on LLC is made by decomposing recursively to region. And, with transposing data enough at first, data of another region composed are not required later.
