Abstract
We implemented a parallel Swendsen-Wang algorithm for a 2D Ising syste m without magnetization in a host-node programming model. The simulati ons were performed on the Intel Hypercube IPSC/860. Our maximum number of updates/s on 32 nodes 1st three times as high as in the implementa tion by Stauffer and Kertesz on the same machine. With 32 processors w e reach half the speed of the simulations by Tamayo and Flanigan on 25 6 nodes of a CM5. We discuss the non-equilibrium relaxation for the en ergy and the magnetization.
