Issue Date: | 2016 | Journal: | IEEE Transactions on Parallel and Distributed Systems | Abstract: | A two-dimensional Ising model with nearest-neighbors ferromagnetic interactions is implemented in a Field Programmable Gate Array (FPGA) board.Extensive Monte Carlo simulations were carried out using an efficient hardware representation of individual spins and a combined global-local LFSR random number generator. Consistent results regarding the descriptive properties of magnetic systems, like energy, magnetization and susceptibility are obtained while a speed-up factor of approximately 6 times is achieved in comparison to previous FPGA-based published works and almost $10^4$ times in comparison to a standard CPU simulation. A detailed description of the logic design used is given together with a careful analysis of the quality of the random number generator used. The obtained results confirm the potential of FPGAs for analyzing the statistical mechanics of magnetic systems. | URI: | http://hdl.handle.net/10553/114787 | ISSN: | 1045-9219 | DOI: | 10.1109/TPDS.2015.2505725 | Source: | IEEE Transactions on Parallel and Distributed Systems [ISSN 1045-9219], v. 27(9), p. 2618 - 2627 |
