We propose a new model for scaling applications with increasing power budget, which we call the iso-powerefficiency function. We show that viewing scaling in this way has advantages over the previously proposed is efficiency function that assumes all processors run at maximum power. Our experimental results show that over provisioning can result in better(More)
As the number of cores grow in HPC systems, so does the effect of system noise on applications running on these systems. With the knowledge that future large-scale parallel computer systems, including exascale systems, will operate under an overall power bound, we claim to have found a solution that can counter the effects of noise. We present two methods(More)
