Abstract
Distributed Shared memory (DSM) has become an accepted
abstraction for programming distributed systems. Although DSM simplifies
the programming of distributed applications, maintaining a consistent shared
memory can be expensive.
Weakly ordered systems which use synchronization information have
been proposed to reduce the frequency of communication between processors.
We have implemented a weakly ordered system based on the Causal memory mode.
We provide language and runtime support which allow programs to run
efficiently on Causal memory.
Actual implementation results show a significant reduction in the
number of messages when compared to a system maintaining a consistent shared
memory.
