On the basis of optimization and analysis of the serial codes,a new method is raised to solve the algebraic equations by parallel mode,which is by the way of modification to tri-diagonal matrix algorithm arithmetic.Computation and solution of the algebraic equations coefficient can realize parallel compute.Based on MPI(Message Passing Interface),the parallel codes development of TK-2DC has been accomplished.The parallel program is well applied to navigation regulation engineering of Daijiazhou section and Guniusha section in the middle reaches of the Yangtze River.The test results of parallel program on the 16 CPU cores of the Lenovo DeepComp 1800 cluster system indicate that the speedup can reach 4.98 prior to the traditional partition arithmetic.
