RESUMO

Performance prediction is an important mechanism to evaluate the use of resources and predict the execution time of applications in parallel systems. This work presents a tool for the creation of models that represent applications and computers characteristics. Such models are combined to generate a performance model, whose analysis derives execution time estimates that include delay factors, such as arithmetic operations on different data types and contention effects caused by process concurrence. The estimates can be generated in a few seconds and allow the analysis of the impact caused in the application by changes in the parallel system configuration. The tool was implemented for a Java based parallel processing system called JoiN and it showed that satisfactory execution time estimates can be obtained for several types of parallel applications
