Efficient Monte Carlo simulations using a shuffled nested Weyl sequence random number generator

摘要

The pseudorandom number generator proposed recently by Holian et al. [B. L. Holian, O. E. Percus, T. T. Warnock, and P. A. Whitlock, Phys. Rev. E 50, 1607 (1994)] is tested via Monte Carlo computation of the free energy difference between the defectless hcp and fee hard sphere crystals by the Frenkel-Ladd method [D. Frenkel and A. J. C. Ladd, J. Chem. Phys. 81, 3188 (1984)]. It is shown that this fast and convenient for parallel computing generator gives results in good agreement with results obtained by other generators. An estimate of high accuracy is obtained for the hcp-fcc free energy difference near melting. [S1063-651X(99)09412-X]. [References: 22]
