Hadron spectra and elliptic flow in high-energy heavy-ion collisions arestudied within a (3+1)D ideal hydrodynamic model with fluctuating initialconditions given by the AMPT Monte Carlo model. Results from event-by-eventsimulations are compared with experimental data at both RHIC and LHC energies.Fluctuations in the initial energy density come from not only the number ofcoherent soft interactions of overlapping nucleons but also incoherentsemi-hard parton scatterings in each binary nucleon collision. Mini-jets fromsemi-hard parton scatterings are assumed to be locally thermalized through aGaussian smearing and give rise to non-vanishing initial local flow velocities.Fluctuations in the initial flow velocities lead to harder transverse momentumspectra of final hadrons due to non-vanishing initial radial flow velocities.Initial fluctuations in rapidity distributions lead to expanding hot spots inthe longitudinal direction and are shown to cause a sizable reduction of finalhadron elliptic flow at large transverse momenta.
