A New Grid Computing Theory Model to Large-scale CORS

To solve the problems in the construction of large-scale continuously operating reference stations,a new computing theory model is proposed,called as parallel multi-type computer with active memory (PM-CAM) ,based on the models of RAM,CAM and LogP. Then,the feasibility of using PM-CAM model as the grid computing theory model is discussed in detail. The relationship between the model and the grid framework is elaborated. Finally,the model is applied to describe the complex and performance of parallel computing of large-scale CORS,and an instance is presented.
