Multiset signatures for transactional memory
Proceedings of the international conference on Supercomputing, 2011Transactional Memory (TM) systems must record the memory locations read and written (read and write sets) by concurrent transactions in order to detect conflicts. Some TM implementations use signatures for this purpose, which summarize read and write sets in bounded hardware at the cost of false positives (detection of non-existing conflicts).

Transactional memory in a dynamic language
Computer Languages, Systems & Structures, 2009Concurrency control is mostly based on locks and is therefore notoriously difficult to use. Even though some programming languages provide high-level constructs, these add complexity and potentially hard-to-detect bugs to the application. Transactional memory is an attractive mechanism that does not have the drawbacks of locks, however, the underlying ...

Proceedings of the 23rd international conference on Parallel architectures and compilation, 2014
The Intel Haswell processor includes restricted transactional memory (RTM), which is the first commodity-based hardware transactional memory (HTM) to become publicly available. However, like other real HTMs, such as IBM's Blue Gene/Q, Haswell's RTM is best-effort, meaning it provides no transactional forward progress guarantees.

The term “Transactional Memory” was coined back in 1993, but even today, there is a vigorous debate about what it means and what it should do. This debate sometimes generates more heat than light: terms are not always well-defined and criteria for making judgments are not always clear.

2006 IEEE Hot Chips 18 Symposium (HCS), 2006
This article consists of a collection of slides from the author's conference presentation on software transactional memory (STM). Some of the specific topics discussed include: how to translate a language construct via STM, including runtime and compiler support; example of hybrid TM; and the outlook for the future development STM and the applications ...

A shared data structure is lock-free if its operations do not require mutual exclusion. If one process is interrupted in the middle of an operation, other processes will not be prevented from operating on that object.
