This pattern has been implemented in several ways for different architectural levels, achieving significant results for high performance computing. However, developing optimized code with those solutions requires specialized knowledge in each framework?s interface and programming language. Recently, the DSL-POPP was proposed as a framework with a high-level language for patternsoriented parallel programming, aimed at abstracting complexities of parallel and distributed code. Inspired on DSL-POPP, this work proposes the implementation of a unified MapReduce programming interface with rules for code transformation to optimized solutions for shared-memory multi-core and distributed architectures. The evaluation demonstrates that the proposed interface is able to avoid performance losses, while also achieving a code and a development cost reduction from 41.84% to 96.48%. Moreover, the construction of the code generator, the compatibility with other MapReduce solutions and the extension of DSL-POPP with the MapReduce pattern are proposed as future work. / Visando melhoria de performance, simplicidade e escalabilidade no processamento de dados amplos, o Google prop?s o padr?o paralelo MapReduce. Este padr?o tem sido implementado de variadas formas para diferentes n?veis de arquitetura, alcan?ando resultados significativos com respeito a computa??o de alto desempenho. No entanto, desenvolver c?digo otimizado com tais solu??es requer conhecimento especializado na interface e na linguagem de programa??o de cada solu??o. Recentemente, a DSL-POPP foi proposta como uma solu??o de linguagem de programa??o de alto n?vel para programa??o paralela orientada a padr?es, visando abstrair as complexidades envolvidas em programa??o paralela e distribu?da. Inspirado na DSL-POPP, este trabalho prop?e a implementa??o de uma interface unificada de programa??o MapReduce com regras para transforma??o de c?digo para solu??es otimizadas para arquiteturas multi-core de mem?ria compartilhada e distribu?da. A avalia??o demonstra que a interface proposta ? capaz de evitar perdas de performance, enquanto alcan?a uma redu??o de c?digo e esfor?o de programa??o de 41,84% a 96,48%. Ademais, a constru??o do gerador de c?digo, a compatibilidade com outras solu??es MapReduce e a extens?o da DSL-POPP com o padr?o MapReduce s?o propostas para trabalhos futuros.
