Fast vectorized algorithm for the Monte Carlo Simulation of the Random Field Ising Model

High Energy Physics - Lattice 2009-10-22 v1

Abstract

An algoritm for the simulation of the 3--dimensional random field Ising model with a binary distribution of the random fields is presented. It uses multi-spin coding and simulates 64 physically different systems simultaneously. On one processor of a Cray YMP it reaches a speed of 184 Million spin updates per second. For smaller field strength we present a version of the algorithm that can perform 242 Million spin updates per second on the same machine.
