A data re-distribution approach is used to solve the low parallelism problem for column-wise distribution (CWD) in the method.

The inverse iteration method using the proposed method is evaluated with a PC cluster and three kinds of super-computers in Japan, which are the HITACHI SR8000/MPP, Fujitsu VPP800/63, and NEC SX-5/128M8.
