Abstract

This paper describes an efficient implementation of Scope, a coordination language for open distributed systems. We use distributed broadcasts for the IN primitive, which allows tuples to be placed on the most appropriate node and easily migrated. We test the performance of our reference implementation over a geographically-distributed network, and show how scopes can used to optimise the placement of tuples, minimising the effects of network latency and making full use of available bandwidth.
