Framework for Improving Parallelism by Write-Update Coherence Protocol in Distributed Shared Memory System
Source: Academy Publisher
For increasing parallelism in DSM System, the replication of data is to be done. The replication of data increases parallelism by allowing reads of the same data to be executed in parallel. However there is inconsistent result occurring for parallel writes and required to maintain memory consistency. The coherency protocol is required to maintain memory consistency for ensuring the serialization of write operation and that any subsequent reads or writes access the update data. The updates are propagated by the remote site. Now it is upto the coherency protocol to take these update and incorporate the update into the local copies.
