The emergence of multicore processors has renewed interest in the idea of entering transactions into the programming model that is used to write parallel programs. The ACI (atomicity, consistency, isolation) the nature of the transaction provides a basis to ensure that simultaneously read and write shared data does not produce results that are inconsistent or incorrect. In addition, the isolation ensures the transaction produces the same result as if no other transactions that execute concurrently. Although the transaction is not a parallel programming panacea, they shift much of the burden of synchronization and coordination of parallel computation of the programmer to a compiler, runtime system, and hardware.
