ACM Queue: Unlocking Concurrency - Multicore programming with transactional memory

TM (transactional memory) provides a new concurrency-control construct that avoids the pitfalls of locks and significantly eases concurrent programming. It brings to mainstream parallel programming proven concurrency-control concepts used for decades by the database community. Transactional-language constructs are easy to use and can lead to programs that scale. By avoiding deadlocks and automatically allowing fine-grained concurrency, transactional-language constructs enable the programmer to compose scalable applications safely out of thread-safe libraries.

Nothing new here for LtU regulars, I guess, but you may still want to check out this column.
