The paper describes the RAMZES-KP code (for gas dynamic equations with regard to heat conduction) for a hybrid-architecture parallel computer comprising general-purpose processors and graphics accelerators. Program profiling and optimization results are presented. The paralleling efficiency values achieved by using a homogeneous multiprocessor (with general-purpose processors only) and a hybrid computer to solve the same problems are given. Keywords: RAMZES-KP, graphics accelerators, arithmetic accelerators, acceleration, paralleling, MPI, efficiency, implicit gas dynamics, heat conduction.
