“…It may be possible to apply many types of memory consistency models with no effect to the programming since processes cannot directly access the internal state of a shared object. Generally in ODSM, the update or the invalidation coherence policy is used [5]. For synchronization generally locks and barriers are used.…”

The Distributed Shared Memory (DSM) system is designed on the basis of page-based, shared-variablebased or object-based access. There are certain advantages and disadvantages of each access methodology. Comparison of such different access types in a distributed environment is based on parameters namely, type of operation (data read or update), maintenance of consistent data copies on all nodes accessing shared data, administration of data manipulations on multi-computers, etc. This paper compares the design and implementation issues for page-based and object-based DSM in a multicomputing environment. The paper also proposes a hybrid model for implementation of a DSM system that combines some features of page-based and objectbased access that is focused on efficient data access with optimum performance with respect to memory access and cohesive data/object organization. Thus the hybrid model is proposed to get a common function of data sharing by using the best features of both pagebased and object-based DSM models.
