WebTransactional memory is a concurrency synchronization mechanism that combines groups of statements in transactions, that are atomic (either all statements occur, or nothing occurs) isolated (statements in a transaction may not observe half-written writes made by another transaction, even if they execute in parallel) 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 concurrency control mechanism analogous to database transactions for controlling access to shared memory in concurrent computing. Transactional memory systems provide high-level abstraction as an alternative to low-level thread synchronization. This abstraction allows for coordination betwe…
