Demand Transformation Analysis for Concurrent Constraint Programs

interpretation. In the context of stream parallelism, this analysis identi es an amount of input data for which predicate execution can safely wait without danger of introducing deadlock. We assume that programs are well-moded and prove that our analysis is safe. We have constructed an implementation of this analysis and tested it on some small, illustrative programs and have determined that it gives useful results in practice. We identify several applicationsof the analysisresults to distributed implementations of concurrent constraint languages, including thread construction and communication granularity control. This analysis will enable existing computational cost estimation analyses to be applied to stream-parallel logic languages. /
