6th Workshop on the Theory of Transactional Memory
EuroTM WTTM 2014

July 15, 2014, Paris, France - in conjunction with PODC 2014

The workshop has received funding by the European Cooperation in Science and Technology (COST) Action IC1001 Euro-TM.

The 6th Workshop on the Theory of Transactional Memory is a forum to foster exchanges, discussions, and disseminations among researchers on theoretical challenges and recent achievements in the context of speculative concurrent computing with emphasis on transactional memory. Transactional memory (TM) is a promising programming paradigm for simplifying concurrent programming. This abstraction raises several challenges in the way we view synchronization as well as in the way we implement it. A major goal of the workshop is to explore new directions and approaches for reasoning about transactional memory.

Topics of interest include, but are not limited to:

Invited speakers

Prof. Shlomi Dolev, Ben Gurion University, Israel
Prof. Idit Keidar, Technion Haifa, Israel
Dr. Maged Michael, IBM Thomas J. Watson Research Center, USA
Prof. Michael Scott, Rochester University

Celebration of Maurice Herlihy's Birthday

This year WTTM will celebrate the birthday of Maurice Herlihy, as a token of gratitude for his seminal contributions to the area of Transactional Memory.


We solicit submissions describing recent results and/or position papers relevant to the theory of speculative computing with emphasis on transactional memory to be presented and discussed at the workshop. Submissions should be in English and in PDF format. Submissions have to include: a title, authors' name and affiliation, and an up to four-page abstract (additional materials may be added to an optional appendix). Papers are to be submitted electronically at


Final papers will be available to participants electronically during the workshop. However, to facilitate resubmission to more formal venues, no archival proceedings will be published. Authors will have the option to upload the final version of their papers on the workshop website.
