In this project, we investigate the GPU accelerated Monte Carlo simulations of the 2D Ising model. Parallel single-site flips will be applied to a lattice of a fairly large size up to 1024*1024.
Two functions, show_lattice and test_temperature, are designed to test the Ising model.
void show_lattice(const int N, const double beta, const int ITER);
displays the lattice of size N for given inverse temperature beta, where ITER specifies the number of iterations.
void test_temperature(const int N, const int ITER);
computes 4 physical quantities: M (magnetization), X (susceptibility), E (energy), C (specific heat) for a lattice of size N.
These functions are defined in test.cu and called main.cu. You can modify parameters in main.cu and choose one function of them to call.
