| Abstract: | The computation-intensive tasks in the data processing for satellite gravity are analyzed and some key tasks which need to be parallelized for the performance improvement are summarized.By the comparison between the parallelization methods,the OpenMP is adopted and the validity of the parallelization is demonstrated by some examples.The results show that the parallel computing can improve the efficiency of the data processing in satellite gravity mission remarkably. |
