| Abstract: | Solution to partial differential equations are requied in many engineering applications. The grid method is an iterative technique for speeding up the sulution of these equtions.The author describe a model of parallel computing by the alternating direction implicit method, which decreases the communication complexity and can aquire high efficiency. Architecture, shared data and their source and destination are discussed. The implementation of the computing on the given architecture is also given. |
