| Abstract: | In order to solve the problem about magnanimous computation of the area computation under the NURBS curve, the high performance grid parallel computational method is studied and realized. Combining the Romberg integral with the MPI technology, the communication load is achieved to be the smallest. After test, computation time is inversely proportional to the parallel computation processor number. |
