View-based consistency and its implementation

The paper proposes a novel view based consistency model for distributed shared memory. A view is a set of ordinary, data objects that a processor has the right to access in a data-race-free program. The view based consistency model only requires that the data objects of a view are updated before a processor accesses them. Compared with other memory consistency models, the view based consistency model can achieve data selection without user annotation and can reduce much false-sharing effect. This model has been implemented based on TreadMarks. Performance results have shown that for all our applications, the view based consistency model outperforms the lazy release consistency model
