A Case Study on Expressiveness and Performance of Component-Oriented Parallel Programming Francisco Heron de Carvalho Junior 1,* , Cenez Ara´ ujo de Rezende 1 a Campus Universit´ario do Pici - Bloco 910 DepartamentodeComputa¸c˜ao Universidade Federal do Cear´a Abstract Component-oriented programming has been applied to address the require- ments of large-scale applications from computational sciences and engineer- ing that present high performance computing (HPC) requirements. However, parallelism continues to be a challenging requirement in the design of CBHPC (Component-Based High Performance Computing) platforms. This paper presents strong evidences about the efficacy and the efficiency of HPE (Hash Programming Environment), a CBHPC platform that provides full support for parallel programming, on the development, deployment and execution of numerical simulation code onto cluster computing platforms. Keywords: high performance computing, component-based software engineering, parallel programming, performance evaluation * Corresponding author Email addresses: heron@lia.ufc.br (Francisco Heron de Carvalho Junior), cenezaraujo@gmail.com (Cenez Ara´ ujo de Rezende) URL: http://www.lia.ufc.br/~heron (Francisco Heron de Carvalho Junior) Preprint submitted to Science of Computer Programming January 1, 2013
