A given point in this space represents a certain trade-off between those two measures, which will be exp...
Home-based consistency model, a variant of lazy release consistency model (LRC), is a recent development in the DSM field that has open out many areas for further research and development. In this paper, we present 2 adaptive schemes for home-based DSM systems: home migration and dynamic adaptation between write-invalidation and writeupdate protocols. The two fully automatic schemes are in line...
