RESUMO

The contribution of traditional scientic libraries shows to be consolidated in the construction of high-performance applications. However, such an artifact of development possesses some limitations in integration, productivity in large-scale applications, and exibility for changes in the context of the problem. On the other hand, the development technology based on components recently proposed a viable alternative for the architecture of High-Performance Computing (HPC) applications, which has provided a means to overcome these challenges. Thus we see that the scientic libraries and programming orientated at components are complementary techniques in the improvement of the development process of modern HPC applications. Accordingly, this work aims to propose a systematic method for the integration of scientic libraries on a platform of parallel components, HPE (Hash Programming Environment), to oer additional advantageous aspects for the use of components and scientic libraries to developers of parallel programs that implement high-performance applications. The purpose of this work goes beyond the construction of a simple encapsulation of the library in a component; it aims to provide the benets in integration, productivity in large-scale applications, and the exibility for changes in the context of a problem in the use of scientic libraries. As a way to illustrate and validate the method, we have incorporated the libraries of linear systems solvers to HPE, electing three signicant representatives: PETSc, Hypre, e SuperLU.
