Before revision:  We experimentally evaluate our approach using 6 large graph datasets and demonstrate an average 2.7x speedup in execution time and 1.7x reduction in communication  , compared to the state of the art .
After revision:  We experimentally evaluate our approach using 6 large graph datasets and demonstrate an average 2.7x speedup in execution time and 1.7x reduction in communication volume , compared to the state of the art .
