Distributed Shared Memory

Distributed Shared Memory. Distributed Shared Memory Making the main memory of a cluster of computers look as though it is a single memory with a single address space. Then can use shared memory programming techniques. DSM System Still need messages or mechanisms to get data to processor, but

Distributed Shared Memory

Distributed Shared Memory. DSM provides a virtual address space that is shared among all nodes in the distributed system. Programs access DSM just as they do locally. An object/data can be owned by a node in DSM. Initial owner can be the creator of the object/data.
