Abstract
The aim of this work is to develop algorithms and scalable software for petaflop supercomputers to be used for solving nonlinear coefficient inverse problems of wave tomography with extremely large data volumes and super-high resolution. We propose a program structure that allows computations to be parallelized with a high degree of scalability. Some issues of computational efficiency are discussed and the results of our computations performed on 20480 computer cores of the «Lomonosov» supercomputer of the Supercomputing Center of Lomonosov Moscow State University are reported.
