This work presents a study about the use of standards and directions on parallel programming in distributed systems, using the MPI standard and PETSc toolkit, performing an analysis of their performances over certain mathematic operations involving matrices. The concepts are used to develop applications to solve problems involving Principal Components Analysis (PCA), which are executed in a Beowulf cluster. The results are compared to the ones of an analogous application with sequencial execution, and then it is analized if there was any performance boost on the parallel applicationEste trabalho apresenta um estudo sobre o uso de padrões e diretivas de programação paralela em sistemas distribuídos, utilizando o padrão MPI e o conjunto de fe...
