Abstract

The invention discloses a method of super-dimensional river dynamics self-adaptive parallel monitoring, which includes the steps as following: input super-dimensional data into a system and classify according to the different dimension where the data are; create a super-dimensional unstructured grid river dynamics model based on a characteristic-type high-resolution numerical algorithm; in terms of an efficient parallel algorithm in a super-dimensional fluid splitting scheme, perform intra-dimensional and inter-dimensional calculations; the calculation region is divided into a plurality of sub-regions, each sub-region is mapped on a calculation node on the parallel system structure, the communication between the nodes uses a standard message passing interface, the overlapped parallel optimization technique of calculation and communication in the self-adaptive grid, and the calculation of variables associated with the space is independent. The method in the invention puts the super-dimensional river dynamics into the adaptive grid to execute the efficient parallel calculation of splitting scheme, and simultaneously processes the change of dimension; the method realizes the monitoring of river conveniently, timely and high accurately.
