Abstract: This paper analyses the problems of some applications on the traditional distributed parallel computing and running on the grid, extends the Log P parallel computing model to the grid and presents the double Log P model. And then it presents the strategy to design parallel algorithm on the grid, finally improves the parallel algorithm of CG according to the characters of the grid.
