A Vectorization Technique for a Family of Finite Difference Formulae and Its Performance Evaluation

In this contribution the vectorization technique on the current vector supercomputer are derived from the relation between the number of gridpoints in the x, y directions in three dimension. This technique is applied to vectorization of the SOR method. Moreover the actual efficiency on the vector supercomputer is examined, and it is shown that the SOR method vectorized by this technique has a high efficiency as more than 90% of the maximum speed of the vector supercomputer.
