SSE-algorithm of molecular dynamics

C++ program for coprocessor and assembler program for multimedia SSE-registers are described. They calculate distances and forces for simple spherical particles interact according to Lennard-Jones potential in off lattice molecular dynamics with periodic boundary conditions. The assembler program quickens up integration of motion equations more then twice relative tp the same algorithm executing by coprocessor under equal terms. The assembler program permits to vary parameters of Lennard-Jones potential, including mixture simulation of spherical particles of different size and various interaction energies. Besides it is needless particles number would be multiple of four. The structured algorithm permits to use another type of short range potential by remaking of one block only. The algorithm also operates with chain molecules which lengths are less then simulating system size.
