Program performance test based on different computing environment

To test the efficiency of different programming languages and find out the suitable one for solving the calculation problem of spherical distance between two points, we have developed serial and parallel calculate algorithms according C, Python programming languages, and tested the execution speed of all algorithms. As for the inefficiency of Python, we improved the performance by replacing some functions and variables of Python procedure with Cython. The experimental results show that Python programs can get the same execution efficiency as C language does with the same Large-scale computing environment.
