RESUMO

In the present work we adress the issue of preformance analysis of parallel scientifc applications. We propose a methodology for building analytic models for parallel programs executing on a shared memory multiprocessor system. The methodology is based on the building and integration of two submodels. The first submodel represents the program code and its execution flow, including distribution of tasks among the processor elements. The second is basically a memory interference model that represents the contention for shared memory resources. A low cost performance model is built to illustrate the use of the methodology, which is validated by simulations.
