Abstract
A new stochastic algorithm for calculating the properties of Hamiltonian lattice field theories is described. This approach improves the efficiency as well as the statistical accuracy of projector-method simulations. As an example, this new method (called parallel scoring) is applied to periodic QED. Parallel scoring is the software equivalent of parallel processing. Its advantages and disadvantages are illustrated and discussed. Numerical results from the application of the parallel-processing algorithm to periodic QED in two space dimensions are presented and compared to earlier work.
