Memory transaction
Transactional memory provides optimistic concurrency control by allowing threads to run in parallel with minimal interference. The goal of transactional memory systems is to transparently support regions of code marked as transactions by enforcing atomicity, consistency and isolation. Meer weergeven In computer science and engineering, transactional memory attempts to simplify concurrent programming by allowing a group of load and store instructions to execute in an atomic way. It is a Meer weergeven The abstraction of atomicity in transactional memory requires a hardware mechanism to detect conflicts and undo any changes made to shared data. Hardware … Meer weergeven • Hardware: • Software: Meer weergeven • Memory semantics • Automatic mutual exclusion Meer weergeven In concurrent programming, synchronization is required when parallel threads attempt to access a shared resource.
