"Balanceamento de cargas de aplicações SPMD em sistemas computacionais distribuídos"
Keywords in Portuguese
balanceaento de carga

Abstract in Portuguese
Este trabalho apresenta a implementação e a utilização da migração de processos SPMD (Single Program Multiple Data), a qual realiza somente a transferência dos dados, que estão sendo manipulados pelo processo, para realizar a migração. Seu principal objetivo foi o estudo do impacto do balanceamento de carga no desempenho de aplicações, desenvolvidas utilizando o modelo de programação SPMD. Depois de realizados testes com aplicações SPMD reais, em sistemas computacionais distribuídos utilizando a migração de processos SPMD, foi possível verificar que ganhos de desempenho podem ser alcançados, tanto na migração de processos quanto no tempo de execução de aplicações paralelas SPMD.

Abstract in English
This research presents the implementation and use of the SPMD (Single Program Multiple Data) process migration, which only does the transference of the data that are being used by the process, to perform the process migration. Its main objective was the study of the load balancing impact in the performance of applications developed using the SPMD programming model. After performing the tests with real SPMD applications, in distributed computational systems using the SPMD process migration, it was achieved good performance gains, both in the process migration and in the time execution of applications SPMD parallel applications.
