The execution time for one iteration is equal to the sum of the maximum computation time for all nodes with the new scaling factors and the communication time of the slowest node without slack time during one iteration. - The slowest node $h$ is the node which takes the maximum execution time to execute an iteration before scaling down its frequency. +The slowest node in cluster $h$ is the node which takes the maximum execution time to execute an iteration before scaling down its frequency. It means that only the communication time without any slack time is taken into account. Therefore, the execution time of the application is equal to the execution time of one iteration as in Equation (\ref{eq:perf}) multiplied by the
