摘要

Effectively managing shared memory in a multi-threaded environment is critical in order to achieve high performance in multi-core hardware platforms. Software Transactional Memory (STM) is a scheme for managing shared memory in a concurrent programming environment. STM views shared memory in a way similar to that of a database; read and write operations are handled through transactions, with changes to the shared memory becoming permanent through commit operations. Furthermore, its benefits are not attained until larger data structures are used. Currently there are varying methods for collision detection, data validation, and contention management, each of which has different situations in which they become the preferred method. This paper discusses problems surrounding contention management, related work addressing these problems, a new dynamic contention manager algorithm yielding an Adaptive STM (ASTM) library, experimental results comparing static versus dynamic contention management, and an analysis of the result.
