Scope Consistency : A Bridge between Release Consistency andEntry
Systems that maintain coherence at large granularity such as shared virtual memory systems, suuer from false sharing and extra communication. Relaxed memory consistency models have been used to alleviate these problems, but at a cost in programming complexity. Release Consistency (RC) and Lazy Release Consistency (LRC) are accepted to ooer a reasonable tradeoo between performance and programmin...
متن کاملAn Improved Lazy Release Consistency Model
Problem statement: A network of workstations, viewed as a distributed shared memory system can be used to develop and test parallel algorithms. Approach: For implementing parallel algorithms on such DSMs shared memory consistency model plays a vital role. Results: However on a LAN, strict consistency models like Sequential Consistency model (SC) are not useful since the communication is slow. I...
متن کاملMultiple-Writer Entry Consistency
In this paper, we present the design, implementation and evaluation of a new distributed shared memory (DSM) coherence model called multiple-writer entry consistency (MEC). MEC combines the eecient communication mechanisms of Lazy Release Consistency (LRC) with the exible data management of the Shared Regions 17, 11] and Entry Consistency (EC) models 5]. This is achieved in MEC by decoupling sy...
متن کاملA Comparison of Entry Consistency and Lazy Release Consistency Implementations
This paper compares several implementations of entry consistency (EC) and lazy release consistency (LRC), two relaxed memory models in use with software distributed shared memory (DSM) systems. We use six applications in our study: SOR, Quicksort, Water, Barnes-Hut, IS, and 3D-FFT. For these applications , EC's requirement that all shared data be associated with a synchronization object leads t...
