Updates and News

March 2, 2014: The TRANSACT 2014 Steering Committee is delighted to announce the recipient of its 1st Distinguished Service Award: Mike Spear

March 2, 2014: Best Paper Award Winner: Improved Single Global Lock Fallback for Best-effort Hardware Transactional Memory (Irina Calciu, Tatiana Shpeisman, Gilles Pokam and Maurice Herlihy)

November 19, 2013: Due to multiple requests, the submission deadline has been extended to December 8, 2013. The submission website is now live.


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.


The workshop seeks papers on topics related to all areas of software and hardware for transactional computing. Specific topics of interest include but are not limited to:

Papers should present original research. As transactional memory spans many disciplines, papers should provide sufficient background material to make them accessible to the broader community. Papers focused on foundations should indicate how the work can be used to advance practice; papers on experiences and applications should indicate how the experiments reinforce or reflect principles.


Pleaes use this link to access the submission website.

Papers must be submitted in PDF, and be no more than 8 pages in standard two-column SIGPLAN conference format including figures and tables but not including references. Shorter submissions are welcome. The submissions will be judged based on the merit of the ideas rather than the length. Submissions must be made through the on-line submission site. Final papers will be available to participants electronically at the meeting, but to facilitate resubmission to more formal venues, no archival proceedings will be published, and papers will not be sent to the ACM Digital Library.

Authors will have the option of having their final paper accessible from the workshop website. Authors must be familiar with and abide by SIGPLAN's republication policy, which forbids simultaneous submission to multiple venues and requires disclosing prior publication of closely related work.

At the discretion of the program committee and with the consent of the authors, particularly worthy papers may be recommended for a special journal issue.
