Research and application of parallel computing technology on hydrodynamic model
Ming Yang, Xin Feng Yu · Journal of Sediment Research · 2007
Parallel program design of Yellow River flow-sediment model was realized based on MPI(Message Passing Interface).Load balance of computing quantity was realized through regional division according to distributive storage of data. The mapping relation between whole grids and part-region was established.Special treatments were made at critical units through protocols,input output units and shared nodes.These treatments can decrease communication as much as possible and avoid information-jam.The parallel program can meet the demands of computing capacity and speed in the Yellow River flow-sediment mathematical model.
