Abstract
The Kardar-Parisi-Zhang (KPZ) equation describing kinetic roughening is solved numerically for (3+1)-dimensional systems in the strong-coupling phase. By massive use of supercomputing tools we calculate for the first time the exponent beta (=0.181+or-0.007) with an accuracy comparable with that of lattice growth model simulations. A possible source of errors in parallel Monte Carlo calculations is pointed out.
