The feasibility of the GeoFEM as the platform of parallel finite element method on the earth simulator was investigated. Since the earth simulator consists of 640 SMP nodes and each node has 8 vector processors, there are three level hierarchical parallelization methods: One is inter-node, the others are intra-node and vectorization. The GeoFEM shows extremely high inter-node parallel efficiency, however, it is not yet examined in over one thousand processor environment. Furthermore, the hierarchical architecture of the Earth Simulator requires the optimization for intra-node paralleization and vectorization for better practical performance. Some ordering methods were used to accomplish the intra-node parallelization and vectorization, and we achieved to 10 tera flops on 6.4 GDOF problem finally.
