Manuscript Title: A fast algorithm for investigations on the three-dimensional Ising
model. See erratum Comp. Phys. Commun. 55(1989)251. | ||

Authors: M. Creutz, P. Mitra, K.J.M. Moriarty | ||

Program title: ISING | ||

Catalogue identifier: ACCP_v1_0Distribution format: gz | ||

Journal reference: Comput. Phys. Commun. 33(1984)361 | ||

Programming language: Fortran, Compass. | ||

Computer: CDC CYBER 170-730. | ||

Operating system: CDC NOS 2.1. | ||

RAM: 25K words | ||

Word size: 60 | ||

Keywords: Statistical physics, Thermodynamics, Ising model, Phase transitions, Critical exponents, Correlation functions, Magnetization, Microcanonical methods. | ||

Classification: 23. | ||

Nature of problem:We wish to study the critical temperature and critical exponents of the three-dimensional Ising model. | ||

Solution method:A microcanonical method with demons is used for the simulation of the three-dimensional Ising model. The updating procedure is essentially deterministic and uses only integer arithmetic. Correlations can be measured. | ||

Restrictions:The only restriction on the use of the program is the time needed to acquire reasonable statistics. | ||

Running time:The execution time increases with the number of spin updates required. The program will carry out 860,000 spin updates per second on the CDC CYBER 170-730 or 24,000,000 spin updates per second, including measuring the demon energy and lattice magnetization, on the CDC 7600. The test run output with a reduced lattice size took 4.8 secs on the CDC CYBER 170-730. |
