Resumo

This paper evaluates the power consumption of different parallel programming interfaces (PPI) in a multicore architecture. These PPIs are: PThreads, OpenMP, MPI-1 and MPI-2 (spawn). We measure the total energy and execution time of 11 applications in a single architecture, varying the number of threads/processes. The goal is to show that these applications can be used as a parallel benchmark to evaluate the power consumption of different PPIs. The results show that PThreads has the lowest power consumption among the interfaces, consuming less than the sequential version for memory-bound applications.
