Transactional memory is an appealing technology which frees programmer from lock-based programming. However, most of current hardware transactional memory systems are proposed for multi-core processors, and may face some challenges with the increasing of processor cores in many-core systems, such as inefficient utilization of transactional buffers, unsolved problem of transactional buffer overf...

Transactional programming promises to substantially simplify the development of correct, scalable, and efficient concurrent programs. Designs for supporting transactional programming using transactional memory implemented in hardware, software, and a mixture of the two have emerged recently. To our knowledge, nobody has yet addressed issues involved with debugging programs executed using transa...

In this paper, we present an approach to easily define flexible and reliable services compositions. We introduce a new concept called transactional patterns to specify flexible and reliable composite Web services. A transactional pattern is a convergence concept between workflow patterns and advanced transactional models. It can be seen as a coordination pattern and as a structured transaction....

A major challenge of Transactional memory implementations is dealing with memory accesses that occur outside of transactions. In previous work we showed how to specify transactional memory in terms of admissible interchanges of transaction operations, and gave proof rules for showing that an implementation satisfies its specification. However, we did not capture non-transactional memory accesse...

Transactional data structures with the same performance of highly concurrent data structures enable performance-competitive transactional applications. Although Software Transactional Memory (STM) is a promising technology for designing and implementing transactional applications, STM-based transactional data structures still perform inferior to their optimized, concurrent (i.e. non-transaction...
