| Transactional memory (TM) has been proposed as a new concurrent programming paradigm well-suited for multi-core architecture and simple to reason with. In a TM, processes of an application can communicate using lightweight, in-memory transactions. Basically, a process that wants to access a shared data structure executes some operations on this structure inside a transaction. When the transaction commits, all these operations appear as if they took place instantaneously, at some single, unique point in time. When the transaction aborts, however, all the operations are roll-backed and their effects are never visible to other transactions. | Transactional memory (TM) has been proposed as a new concurrent programming paradigm well-suited for multi-core architecture and simple to reason with.
