The invention relates to a method for carrying out parallelization numerical simulation on hydrodynamic force conditions of a river provided with a cascade hydropower station. According to the method, a closed equation set is established for each course by setting an upper level or a flow-level relation of a river channel structure as a lower boundary condition of an upper reach and supposing that a lower level of the structure is used as an upper boundary condition of a lower reach; and each equation set only comprises variables of the same reach, a coefficient matrix formed by adopting an implicit difference scheme to carry out dispersion are still kept having the banded characteristics and the physically related reaches are relatively independent on the aspect of value, so that the variables of the reaches can be solved by applying the banded matrix and the aim of ensuring the flows at both sides of the structure equal is fulfilled by iterating and correcting the lower level of the structure. Compared with the conventional method of solving the hydrodynamic conditions of the river by the single course, the method disclosed by the invention has the advantages that the rapid parallel solution of the multi-course river hydrodynamic conditions can be implemented without modifying an original sequence program of solving the river hydrodynamic conditions on a large scale; the operation process has short time consumption; and the efficiency is high.

The embodiment of the invention provides a method and a device for embedding a relation network graph in a multi-dimensional space through a distributed architecture. The distributed architecture comprises a plurality of processing devices, wherein one set of nodes of the relation network graph is distributed to each processing device. The method is executed by a certain processing device, and comprises the steps of: determining first-order adjacent nodes of a first node for which the processing device is responsible, determining processing devices corresponding to the first-order adjacent nodes; determining an initial embedding vector of the first node as a current order embedding vector; employing the current order embedding vector of the first-order adjacent nodes to calculate the nextorder embedding vector of the first node, and employing the next order embedding vector to update the current order embedding vector; and continuously executing the updating step until the current order quantity reaches a preset search depth, and taking the current order embedding vector at present as an embedding vector of the multi-dimensional space. Therefore, the distributed graph embedding method and device can effectively embed the relation network graph into the multi-dimensional space.
