Advanced Micro Devices MEMORY TRANSACTIONAL MEMORY SHOULD BE VIRTUALIZED TO SUPPORT TRANSACTIONS OF ARBITRARY FOOTPRINT AND DURATION. UNBOUNDED TRANSACTIONAL-MEMORY ARCHITECTURES CAN ACHIEVE HIGH PERFORMANCE IN THE COMMON CASE OF SMALL TRANSACTIONS, WITHO

Researchers have proposed using transactional memory as a flexible method by which programs can read and modify disparate primary memory locations atomically in a single operation, much as a database transaction can atomically modify many records on disk. 1-6 The basis of transactional memory is atomic transactions, which offer a method of providing mutual synchronization without the protocol intricacies of conventional synchronization methods such as locks. We can think of a transaction as a sequence of loads and stores performed as part of a program. With transactional memory, unlike databases, we need not concern ourselves wit
