for the next step in the path from source to destination. Autonet automatically recalculates these forwarding paths in response to failures and additions of network components. This automatic reconfiguration allows the network to continue normal operation without need of human intervention. Reconfiguration

The goals are to provi-sion server resources for co-hosted services in a way that automati-cally adapts to offered load, improve the energy efficiency of server dusters by dynamically resizing the active server set, and respond to power supply disruptions or thermal events by degrading service

framework for all R&A sys~ terns, We describe a novel software framework, based on the notion of dynamically reconfigurable software for sensor-based control systems. Tools to support the implementation of this framework have been built into the Chimera 3.0 Real-Time Operating System. The framework

services are also briefly discussed. 1 Introduction With the ever increasing dependence on computing services, their availability in the presence of failures, maintenance and horizontal growth becomes of paramount importance. In present systems, responsibility for reconfiguring a system after failures

Reconfigurable hardware is ideal for use in Systems-on-a-Chip, as it provides both hardware-level performance and post-fabrication flexibility. However, any one architecture is rarely equally optimized for all applications. SoCs targeting a specific set of applications can greatly benefit from

Abstract—The configuration of a distributed storage system with multiple data replicas typically includes the set of servers and their roles in the replication protocol. The configuration can usually be changed manually, but in most cases, system adminis-trators have to determine a good configuration by trial and error. We describe a new workload-driven optimization framework that dynamically determines the optimal configuration at run time. Applying the framework to a large-scale distributed storage system used internally in Google resulted in halving the operation latency in 17 % of the tested databases, and reducing it by more than 90 % in some cases. Globally distributed storage systems usually provide con-sistency across replicas of data (or metadata) using serial-ization or conflict resolution protocols. Distributed atomic commit or consensus-based protocols are often used when

In this paper we describe a new hardware/software partitioning approach for embedded reconfigurable architectures consisting of a general-purpose processor (CPU), a dynamically reconfigurable datapath (e.g. an FPGA), and a memory hierarchy. We have developed a framework called Nimble

Reconfigurable hardware has the potential for significant performance improvements by providing support for application−specific operations. We report our experience with Chimaera, a prototype system that integrates a small and fast reconfigurable functional unit (RFU) into the pipeline

This paper presents PixelFlex -- a spatially reconfigurable multi-projector display system. The PixelFlex system is composed of ceiling-mounted projectors, each with computer-controlled pan, tilt, zoom and focus; and a camera for closed-loop calibration. Working collectively, these controllable

. With such freedom in the design space of the processor, however, comes complexity. We present here an automatic optimization technique that helps the developers with the processor microarchitecture customization. A naive approach exploring all possible configurations is exponential with the number of parameters
