A direct numerical simulation is performed for initial perturbation growth in oblique impact of metal plates. The results agree with relevant experimental data. It is confirmed numerically that under experimental conditions the perturbations of wavelength l=0,5 mm grow most intensively. The numerical simulation revealed a number of new effects.

An explicitly implicit algorithm for pressure calculation used to compute problems on computers with distributed memory. The data computed in multiprocessor mode confirm the serviceability of a parallelized program algorithm as well as the acceptable and theoretically expected efficiency of parallelization.
