8th Workshop on the Theory of Transactional Memory
WTTM 2016

July 25, 2016, Chicago, Illinois,USA - in conjunction with PODC 2016

The 8th Workshop on the Theory of Transactional Memory (WTTM) is a forum to foster exchanges, discussions, and disseminations among researchers on theoretical challenges and recent achievements in the context of concurrent computing, with an emphasis on transactional memory.

Transactional Memory (TM) aims at making parallel programming more programmer friendly by providing an alternative synchronization mechanism to traditional lock-based concurrency. TM research has led to hardware TM implementations on both commodity and high performance computing microprocessors, as well as to TM integration in mainstream programming languages (e.g., C, C++) and leading open source compilers (e.g., GCC).

From a theoretical perspective, the TM 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:


We solicit submissions describing research results and/or position papers relevant to the theory of concurrent computing with an emphasis on transactional memory.

Submissions should be written in English and in PDF format. Submissions should include: a title, the authors' names and their affiliations, and the contact author's email. Each submission must not exceed four single-column pages (excluding references) which will describe the results. Additional necessary details may be included in an appendix which will be read at the discretion of the program committee.

Papers are to be submitted electronically at https://easychair.org/conferences/?conf=wttm2016

The final version of the accepted papers will appear on the workshop's web site. These papers will be available to the participants in electronic format during the workshop. WTTM does not publish proceedings, so accepted papers may appear in other venues as well.
