Title in Portuguese
Avaliação de métodos de paralelização automática.
Keywords in Portuguese
Métodos de paralelização
Processamento paralelo
Programação paralela
Abstract in Portuguese
Este trabalho aborda alguns conceitos e definições de processamento paralelo, que são aplicados a paralelização automática, e também às análises e condições para as dependências dos dados, de modo a aplicarmos os métodos de paralelização: Hiperplano, Transformação Unimodular, Alocação de Dados Sem Comunicação e Particionamento & Rotulação. Desta forma, transformamos um programa seqüencial em seu equivalente paralelo. Utilizando-os em um sistema de memória distribuída com comunicação através da passagem de mensagem MPI (Message-Passing Interface), e obtemos algumas métricas para efetuarmos as avaliações/comparações entre os métodos.

Parallelization methods
Abstract in English
This work invoke some concepts and definitions about parallel processing, applicable in the automatic parallelization, and also the analysis and conditions for the data dependence, in order to apply the methods for parallelization: Hyperplane, Unimodular Transformation, Communication-Free Data Allocation and Partitioning & Labeling. On this way, transform a sequential program into an equivalent parallel one. Applying these programs on the distributed-memory system with communication through message-passing MPI (Message-Passing Interface), and we obtain some measurements for the evaluations/comparison between those methods.
