Um Elemento Autonômico para Redes de Sensores Sem Fio

This paper presents the optimization done on collective communication operations of message passing library MPICH version 1.1. The optimization efficiency was demonstrated evaluating the execution time of collective operations and measuring their impact on the total execution time of several application programs. We also compared our results with literature dates. We concluded implementing efficient collective communication operations on cluster based of Ethernet hub provides high performance gain.
