The past decade has seen an explosion of interest in programming languages, systems, and hardware to support transactions, speculation, and related alternatives to classical lock-based concurrency. Recently, transactional memory has crossed two new thresholds. First, IBM and Intel are now shipping processors with hardware support for transactional memory. Second, the C++ Standard Committee has begun investigation into transactional memory as a new language feature. These developments highlight the demand for continued high quality TM research.

This workshop, the ninth in its series, will provide a forum for the presentation of research on all aspects of transactional computing. The scope of the workshop is intentionally broad, with the goal of encouraging interaction across the languages, architecture, systems, database, and theory communities. Papers may address implementation techniques, foundational results, applications and workloads, or experience with working systems. Environments of interest include the full range from multithreaded or multicore processors to high-end parallel computing.
