Resumo: |
Transactional Memory is considered by many researchers to be one of the most promising solutions to address the problem of programming multicore processors. This model provides the scalability of fine-grained locking while avoiding common issues of tradicional mechanisms, such as deadlocks. During these almost twenty years of research, several studies were carried out to identify approaches in order to maximize the use of Transactional Memories in the Parallel Programming scenario. Furthermore, several TM systems have been developed in different types of implementations as well as new Benchmarks were proposed for evaluation and testing of TM systems. However, despite advances in the area, Transactional Memory is not considered yet a ready solution by the scientific community, due to unanswered questions in the literature, such as: How to identify if an application has an advantage using Transactional Memory? and Why some applications do not benefit from the use of Transactional Memories? , This work presents a comparative evaluation of a set of transactional applications and systems, introducing the field current state-of-the-art, understanding the existing problems and identifying growth opportunities in the STM systems in order to contribute to answer the questions that remain open in the scientific community. |
