%X Distributed Shared Memory (DSM) has many advantages in
   heterogeneousenvironments, such as geographically distant
   clusters or The Grid. These includes:locality utilization
   and replication transparency. The fact that processes
   communicateindirectly through memory rather than directly,
   is giving DSM these advantages.This paper presents the
   design of Global PastSet (GPS) which is a DSM systemtargeted
   at global area networks. GPS is based on the DSM system
   PastSet [1] that hasbeen very effective in homogeneous
   cluster environments. GPS utilizes consistencycontrol
   migration and replication to scale in heterogeneous
   environments. This hasresulted in a token\-based mutual
   exclusion algorithm that considers locality and analgorithm
   for locating replicas. GPS has been simulated in
   multi\-cluster environmentswith up to 2048 nodes with very
   promising results.
