Fully implicit method with lower upper symmetric Gauss-Seidel preconditioner on multiple graphics processing units for hypersonic flows

In the paper, we present implementation and benchmarking for gas dynamic solver for hypersonic flow problems with fully implicit scheme. The aim of the paper is to verify and measure efficiency of the implicit method for computational architecture based on multiple graphics processing units. The verification is performed on a flow over the sphere-cone problem. We consider hypersonic flow regimes of Mach number around 20-30. New results are cross-compared with results of the previous version of the code for explicit time marching scheme.
