RESUMO

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 the customers have great expectative regarding the release time. As consequence of the technological evolution and the price reduction of the processors and memories, modern systems with high performance, as the parallel processing systems, have gained more relevance and they have been progressively more requested by the customers due to their computational power to solve complex problems in critical fields such as medical, military, energy, simulation and weather forecasts (MORRISON, 03). In the parallel processing area, it is reasonable to affirm that there is a real race to release a new product and its versions earlier in the market, to get a better position and more advantages than the competitors and to become a reference for the customers, who then wish to adopt it. Taking these facts into consideration, the problem studied in this thesis is how to improve the development process of parallel processing systems, reducing the development time of new versions of these systems. The proposal to solve this problem is to reduce the test time, which corresponds to a significant part of the total project time. In order to achieve this reduction, this work presents a strategy based on the parallel execution of the test with the development. The application of this technique to the parallel processing systems results in the main objective of this work, which is to reduce the development time of new versions of these systems through a test methodology. This methodology is used to test one component of the parallel processing system, called Control System, simultaneously with the development of the other components of the system. To test the efficiency of the proposed solution, the methodology has been applied to the development of the IBM Blue Gene supercomputer. As a result, a reduction of up to 41% of the total project time could be observed.
