Abstract:
A parallel algorithm based on nonlinear conjugate gradient method for solving the inverse structural magnetic problem of finding a boundary surface between two layers with constant arbitrary directed magnetizations using magnetic data and magnetization jump is constructed. The efficient implementation for the multiple GPUs was developed. Investigation of efficiency and speedup of parallel algorithm is performed. A model problem with synthetic magnetic data was solved for a large grid. © 2017 Author(s).
