An MPI implementation of the calculation of the microscopic optical nucleon-nuclear folding potential has been developed. On a heterogeneous cluster " HybriLIT"Multifunctional Information and Computing Complex (MIVK) Calculations of the folding potential and the corresponding differential cross sections of elastic scattering of 11 Li+p at an energy of 62 MeV/nucleon were carried out at the JINR Information Technology Laboratory. The agreement of experimental data and calculation results for different distributions of the 11 Li core density used in the construction of the folding potential is demonstrated.
