     Several direct and iterative methods for solving the inverse gravity problems are proposed and numerically realized on the massively parallel computing system MVS-1000. As a result, we find the variable density in horizontal and curvilinear layers on the basis of gravitational data measured on the ground surface. The speed-up and efficiency of the parallel iterative algorithms are analyzed depending on the number of processors in use. This work was supported by the Russian Foundation for Basic Research (project N 06-01-00116). The paper was prepared on the basis of the authors' report at the International Conference on Parallel Computing Technologies (PaVT-2007; http://agora.guru.ru/pavt2007).
