We study the harmonic flows, for example, the directed, elliptic, third and fourth flows, of the system of partons formed just after relativistic heavy ion collisions. We calculate the minijets produced during the primary collisions by using standard parton distributions for the incoming projectile and the target nucleus. We solve the Boltzmann equations of motion for the system of minijets by using the Monte Carlo method within only the perturbative sector. Based on the calculated flow data, we conclude that the simulation cannot reproduce the experimental results at RHIC and LHC; thus, the nonperturbative sector plays much more important roles even from the earliest stages of heavy ion collisions.
