We promote the use of transactional attributes for modelling business processes in the service-oriented scenario. Transactional attributes have been introduced in Enterprise JavaBeans (EJB) to decorate the methods published in Java containers. Attributes describe “modalities” that discipline the reconfiguration of transactional scopes (i.e., of caller and callee) upon method invocation. An orig...

In this paper, we present a Haskell Transactional Memory benchmark in order to provide a comprehensive application suite for the use of Software Transactional Memory (STM) researchers. We develop a framework to profile the execution of the benchmark applications and to collect detailed runtime data on their transactional behavior. Using a composite of the collected raw data, we propose new tran...

This study investigates how small, resource-constrained firms identify international marketing strategies for perishable products. Although of products poses challenges the exporter, many small companies manage to survive and thrive on an business arena. Over past decades, there has been a growing interest in design their channels. However, little is known about conditions leading choice partic...

We present an analytical performance modeling approach for concurrency control algorithms in the context of Software Transactional Memories (STMs). We consider a realistic execution pattern where each thread alternates the execution of transactional and non-transactional code portions. Our model captures dynamics related to the execution of both (i) transactional read/write memory accesses and ...

We propose a new design for an energy-efficient hardware transactional memory (HTM) system for power-aware embedded devices. Prior hardware transactional memory designs proposed a small, fully-associative transactional cache at the same level as the L1 cache. We propose an alternative design that unifies the transactional and L1 caches, and provides a small victim cache to reduce effects of cap...

In this paper, we present a flexible framework for extending a component model with transactions. We first discuss key issues of combining components with transactions, and different approaches to achieve an appropriate level of transactional functionality in components. We distinguish between the explicit and implicit component participation approaches that differ by whether a component implem...

Hybrid transactional memory (HyTM) [3] works in today’s systems, and can use future “best effort” hardware transactional memory (HTM) support to improve performance. Best effort HTM can be substantially simpler than alternative “unbounded” HTM designs being proposed in the literature, so HyTM both supports and encourages an incremental approach to adopting HTM. We introduce Phased Transactional...

Concurrent programming holds the key to fully utilizing the multi-core chips provided by CMPs. However, traditional concurrent programming techniques based on locking mechanisms are hard to code and error-prone. Transactional Programming is an attempt to simplify concurrent programming where transactions are the main concurrent construct. Hardware Transactional Memory systems provide hardware s...

With the Internet changing from era Web1.0 of computers’ interaction to era Web2.0 of users’ interaction, the development of transactional community has become the key solution to combine economic value with social value in social commerce. Transactional community is different from traditional social community in its relationship establishment because of the unique motivations of their members....
