Block Algebraic Multigrid Method for Saddle-Point Problems of Various Physicsy compressible and incompressible elasticity, multiphase flows in oil & gas problems, the non-stationary Maxwell problem, as well as the Navier–Stokes equations are considered. Most of the problems are of saddle-point nature. Our main goal was not so much to investigate the parallel properties of th

Computational Efficiency of Iterative Methods for Solving Inverse Problems on model problems of breast ultrasound tomographic imaging for early-stage cancer diagnosis. The iterative method is computationally expensive. Computational efficiency of the proposed method on multi-core CPU and GPU computing platforms is discussed.

Parallel Numerical Implementation 3D Wave Hydrodynamics and SWAN Modelssolve hydrodynamic problems using MPI is shown. It was revealed that the speed-up radio reaches the highest value at 128 cores, and with a further increase in the number of computing cores, the acceleration only decreases, which is associated with an increase in the time spent on data exchange betwe
