Energy proportionality of data center severs have improved drastically over the past decade to the point where near ideal energy proportional servers are now common. These highly energy proportional servers exhibit the unique property where peak efficiency no longer coincides with peak utilization. In this paper, we explore the implications of this property on data center scheduling. We identified...
In this paper, we propose a new approach for cross-layer electromigration (EM) induced reliability modeling and optimization at physics, system and datacenter levels. We consider a recently proposed physics-based electromigration (EM) reliability model to predict the EM reliability of full-chip power grid networks for long-term failures. We show how the new physics-based dynamic EM model at the physics...
Cluster-level packing techniques have long been used to improve the energy proportionality of server clusters by masking the poor energy proportionality of individual servers. With the emergence of high energy proportional servers, we revisit whether cluster-level packing techniques are still the most effective way to achieve high cluster-wide energy proportionality. Our findings indicate that cluster-level...
