Improved parallel implementation of the two-dimensional Ising model Original Research Article

Some simulations we would like to perform in computational physics require so much computation time that it is not possible to finish them in reasonable length of time on any nowadays available computer. If it is possible to decompose a compute intensive problem into smaller independent tasks one possibility is to shorten the calculation time is to apply a parallel algorithm. Java, a platform independent programming language changed the way of software design by using Jini and JavaSpaces, new technologies that have been introduced recently. By applying JavaSpaces, a virtual, network accessible space can be used to store Java objects but also for effective parallel processing. In this paper, we report a novel, parallel implementation of the two-dimensional Ising model using the JavaSpaces technology. Our new approach was implemented on standard computer equipment and results in significant improvement of computation time.
