abstract = {Transactional Memory (TM) is reputed by many researchers to be a promising solution to ease parallel programming on multicore processors. This model provides the scalability of fine-grained locking while avoiding common issues of traditional mechanisms, such as deadlocks. During these almost twenty years of research, several TM systems and benchmarks have been proposed. However, TM is not yet widely adopted by the scientific community to develop parallel applications due to unanswered questions in the literature, such as "how to identify if a parallel application can exploit TM to achieve better performance?" or "what are the reasons of poor performances of some TM applications?". In this work, we contribute to answer those questions through a comparative evaluation of a set of TM applications on four different state- of-the-art TM systems. Moreover, we identify some of the most important TM characteristics that impact directly the performance of TM applications. Our results can be useful to identify opportunities for optimizations.},

O conceito de computação em nuvem está cada vez mais presente nas redes de computadores. A dificuldade não está apenas em implantar uma nuvem, mas também em escolher a ferramenta mais apropriada. Assim, este trabalho buscou estudar as seguintes ferramentas: Eucalyptus, OpenNebula, OpenQRM, OpenStack, CloudStack Ubuntu Enterprise Cloud, Abiquo, Convirt, Apache Virtual Lab e Nimbus. Para estas, foram consideradas as características, funcionalidades e formas de operação, evidenciando o cenário mais indicado para cada uma delas.},

abstract = {Pattern-oriented programming has been used in parallel code development for many years now. During this time, several tools (mainly frameworks and libraries) proposed the use of patterns based on programming primitives or templates. The implementation of patterns using those tools usually requires human expertise to correctly set up communication/synchronization among processes. In this work, we propose the use of a Domain Specific Language to create pattern-oriented parallel programs (DSL-POPP). This approach has the advantage of offering a higher programming abstraction level in which communication/synchronization among processes is hidden from programmers. We compensate the reduction in programming flexibility offering the possibility to use combined and/or nested parallel patterns (i.e., parallelism in levels), allowing the design of more complex parallel applications. We conclude this work presenting an experiment in which we develop a parallel application exploiting combined and nested parallel patterns in order to demonstrate the main properties of DSL-POPP.},
