We report on molecular dynamics simulations of spacetime correlations of the
    Toda lattice in thermal equilibrium. The correlations of stretch, momentum, and
    energy are computed numerically over a wide range of pressure and temperature.
    Our numerical results are compared with the predictions from linearized
    generalized hydrodynamics on the Euler scale. The system size is N=3000,4000
    and time t =600, at which ballistic scaling is well confirmed. With no
    adjustable parameters, the numerically obtained scaling functions agree with
    the theory within a precision of less than 3.5%.
