%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.
