A PARALLEL NUMERICAL ALGORITHM BY COMBINING MPI AND OPENMP PROGRAMMING MODELS WITH APPLICATIONS IN GRAVITY FIELD RECOVERY

A parallel numerical algorithm by combining MPI and OpenMP programming models with applications in gravity field recovery

Satellite gravimetry missions have enabled the calculation of high-accuracy and high-resolution Earth gravity field models from satellite-to-satellite tracking data and gravitational gradients.However, calculating high maximum degree/order (e.g., 240 or even higher) gravity field models using the least squares method is time-consuming due to the va
