Irregular applications, which manipulate large, pointer-based data structures like graphs, are
difficult to parallelize manually. Automatic tools and techniques such as restructuring …

Transactional Memory (TM), Thread-Level Speculation (TLS), and Checkpointed
multiprocessors are three popular architectural techniques based on the execution of …

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 …

We describe DSTM2, a Java™ software library that provides a flexible framework for
implementing object-based software transactional memory (STM). The library uses …

Transactional memory systems are expected to enable parallel programming at lower
programming complexity, while delivering improved performance over traditional lock-based …

Transactional Memory (TM) simplifies parallel programming by allowing for parallel
execution of atomic tasks. Thus far, TM systems have focused on implementing transactional …

Nested transactional memory (TM) facilitates software composition by letting one module
invoke another without either knowing whether the other uses transactions. Closed nested …

Transactional memory (TM) promises to simplify concurrent programming while providing
scalability competitive to fine-grained locking. Language-based constructs allow …

In this paper, we propose the use of Versioned Boxes, which keep a history of values, as the
basis for language-level memory transactions. Unlike previous work on software …

Atomos is the first programming language with implicit transactions, strong atomicity, and a
scalable multiprocessor implementation. Atomos is derived from Java, but replaces its …
