Abstract The parallel algorithm based on supercomputer for solving the Earth’s gravity field model was investigated.Shared and distributed parallel environment (OpenMP & MPI) applying to the least squares method are analysed and compared. Different threads, different node to determine the gravity field model at different levels of time consumption and efficiency are compared with each other.
Key words ：
