而现有的并行程序绝大多数是依赖机器的，因此并行程序的可移植性差且难于预测性能。

While present parallel programs mostly machine dependent, so the transportability of parallel programs are very poor and it is very difficult to predict the program performance.

通过对原串行程序进行分析与测试，确定了以曲率计算、第一次差分计算和第二次差分计算等为并行化的重点。

Through the analysis and test of original serial program system, curvature computing and first difference, second difference etc. are defined as key objects.
