A Hierarchical Optimization Architecture for Large-Scale Power Networks

SHIP: A Scalable Hierarchical Power Control Architecture for Large-Scale Data Centers — Supplementary File

The supplementary file of the paper is organized as follows. Section II introduces the power distribution hierarchy used in many data centers. Section III describes the controller design and analysis of the PDU-level power controller. Section IV discusses the rack-level power controller. Section VI provides additional implementation details of our control architecture and additional empirical r...

An NMS Architecture for Large-scale Networks

One of the key characteristics of the contemporary network is its scale. The cloud data center network, which is considered as a key component of the current Internet, is normally composed of tens of thousands of devices. Besides, networks which connect data centers and their users are getting larger and becoming more complex because of the growing bandwidth requirement and user demands. This p...

Hierarchical Power Control for Large-Scale Data Centers

In today’s data centers, precisely controlling power consumption is an essential way to 1) reduce operating costs, and 2) avoid system failures caused by power capacity overload or overheating due to increasingly high server density. While various power control strategies have been recently proposed, existing solutions are not scalable to control the power consumption of an entire large-scale d...

Cross-Validation Optimization for Large Scale Hierarchical Classification Kernel Methods

We propose a highly efficient framework for kernel multi-class models with a large and structured set of classes. Kernel parameters are learned automatically by maximizing the cross-validation log likelihood, and predictive probabilities are estimated. We demonstrate our approach on large scale text classification tasks with hierarchical class structure, achieving state-of-the-art results in an...
