Multicore designs have emerged as the mainstream design paradigm for the microprocessor
industry. Unfortunately, providing multiple cores does not directly translate into performance …

" Is transactional memory useful?" is the question that cannot be answered until we provide
substantial applications that can evaluate its capabilities. While existing TM applications can …

Current hardware transactional memory systems seek to simplify parallel programming, but
assume that large transactions are rare, so it is acceptable to penalize their performance or …

Transactional memory (TM) is a speculative shared-memory synchronization mechanism
used to speed up concurrent programs. Most current TM implementations are software …

Programmers have traditionally used locks to synchronize concurrent access to shared data.
Lock-based synchronization, however, has well-known pitfalls: using locks for fine-grain …

Hardware transactional memory has great potential to simplify the creation ofcorrect and
efficient multithreaded programs, allowing programmers to exploitmore effectively the soon …

Transactional Memory (TM) is a promising technique that simplifies parallel programming for
shared-memory applications. To date, most TM systems have been designed to efficiently …

Applications need to become more concurrent to take advantage of the increased
computational power provided by chip level multiprocessing. Programmers have …

Existing software transactional memory (STM) implementations often exhibit poor scalability,
usually because of nonscalable mechanisms for read sharing, transactional consistency …

The adoption of transactional memory is hindered by the high overhead of software
transactional memory and the intrusive design changes required by previously proposed TM …
