The deconfining finite-temperature transition of SU(3) gauge theory is studied on the dedicated parallel computer QCDPAX. Monte Carlo simulations are performed on 12{sup 2}{times}24{times}4, 24{sup 2}{times}36{times}4, 20{sup 3}{times}6, 24{sup 3}{times}6, and 36{sup 2}{times}48{times}6 lattices with 376 000 to 1 112 000 iterations. The finite size scaling behavior of the first-order transition is confirmed both on the {ital N}{sub {ital t}}=4 and {ital N}{sub {ital t}}=6 lattices and clear two-phase structures are observed on spatially large lattices (24{sup 2}{times}36{times}4 and 36{sup 2}{times}48{times}6). The latent heat at the deconfining transition is estimated both by a direct measurement of the gap on the spatially large lattices and by applying a finite-size scaling law. The results obtained by these two independent methods are remarkably consistent with each other on both the {ital N}{sub {ital t}}=4 and 6 lattices. The latent heat for {ital N}{sub {ital t}}=6 is much smaller than that for {ital N}{sub {ital t}}=4 and is about 1/3 of the Stefan-Boltzmann value 8{pi}{sup 2}/15. The details of the data and the error analysis are presented.
