      abstract     = {Numerical simulations of quantum electrodynamics near the
                      phase transition suffer from an extreme slowing down on
                      large lattices. The two leading terms of the decaying
                      autocorrelation function can be attributed to the influence
                      of first-order phase transition effects, called
                      supercritical slowing down, and second-order phase
                      transition effects, called critical slowing down,
                      respectively. We show that we can bypass supercritical
                      slowing down using a conventional local updating algorithm
                      based on a phenomenological weight ratio fixing method.As
                      for critical slowing down, we apply a new global multi-scale
                      updating algorithm which removes critical slowing down
                      completely. We compare the structure of the local vs. the
                      global algorithm as well as their implementation on the
                      Connection Machine CM-2, analyze their computational
                      complexity and present actual performance measurements.},
