1. Fitting equation of state parameters in parallel computers
This work compares two strategies to fit parameters of equations of state in parallel computers, emphasizing solutions that require few changes to existing sequential programs. One strategy uses the conventional Nelder-Mead algorithm coupled with parallel objective function evaluation (SSPO). The other strategy uses a parallel Nelder-Mead algorithm coupled w

2. Dynamic load-balancing : a new strategy for weather forecast models
Weather forecasting models are computationally intensive applications and traditionally they are executed in parallel machines. However, some issues prevent these models from fully exploiting the available computing power. One of such issues is load imbalance, i.e., the uneven distribution of load across the processors of the parallel machine. Since weather

5. Um modelo de memória transacional para arquiteturas heterogêneas baseado em software Cache / A transactional memory model for heterogeneous architectures based in Software Cache
The adoption of multi-core processors by the industry has pushed towards the development of new techniques to simplify programming parallel software. The technique called transactional memories is one of the most promising. This technique is able to execute multiple tasks concurrently in an optimistic way to achieve a better performance. Another advantage is

9. Metodologia de teste para acelerar o desenvolvimento de sistemas de processamento paralelo. / Test methodology to accelerate the development of parallel processing system.
Due to the great competitiveness of the market, there is an increasing demand for the production of modern computational systems with more quality in less time (CALANTONE; BENEDETTO, 00). The development time of new versions at those systems is also critical, because better performance and more functionalities than in the current version are expected, and th

11. Suporte a simulação distribuída em SystemC
The ever increasing evolution of microelectronics allows the integration of more and more complex systems in semiconductor devices. Present day System on Chip (SoC) may integrate processors, memories, analog, mixed-signals, digital and RF modules in a single chip. The simulation of a SoC is a fundamental step in system design, since it permits the verificati
