The software stack can be a complex, multi-layer, multi-component, concurrent, and parallel environment with multiple contexts of execution and multiple sources of performance data. Although much performance data is available, because modern systems incorporate many mature data-collection mechanisms, analysis algorithms suffer from the lack of a unifying programming environment for processing the collected performance data, potentially from multiple sources, in a convenient and script-like manner.\u0000 This paper presents Weir, a streaming language for systems performance analysis. Weir is based on the insight that performanceanalysis algorithms can be naturally expressed as stream-processing pipelines. In Weir, an analysis algorithm is implemented as a graph composed of stages, where each stage operates on a stream of events that represent collected performance measurements. Weir is an imperative streaming language with a syntax designed for the convenient construction of stream pipelines that utilize composable and reusable analysis stages. To demonstrate practical application, this paper presents the authors' experience in using Weir to analyze performance in systems based on the Xen virtualization platform.","PeriodicalId":7046,"journal":{"name":"ACM SIGOPS Oper.

One important aspect requiring such management is the issue of energy consumption of computing systems, in the perspective of green computing. As these managers address each a specific aspect, there is a need for using several managers to cover all the domains of administration. However, coordinating them is necessary for proper and effective global administration. Such coordination is a problem of synchronization and logical control of administration operations that can be applied by autonomous managers on the managed system at a given time in response to events observed on the state of this system. We therefore propose to investigate the use of reactive models with events and states, and discrete control techniques to solve this problem. In this paper, we illustrate this approach by integrating a controller obtained by synchronous programming, based on Discrete Controller Synthesis, in an autonomic system administration infrastructure. The role of this controller is to orchestrate the execution of reconfiguration operations of all administration policies to satisfy properties of logical consistency. We apply this approach to coordinate three managers : two energy-aware ones, which control server provisioning and processor frequency, and a repair manager.","PeriodicalId":7046,"journal":{"name":"ACM SIGOPS Oper.

Although the schemes leveraging DVFS provide significant power reduction, adverse effects on chip reliability are possible. Alternate increase and decrease in operating voltage and frequency leads to thermal cycling. Increasing transistor packing density leads to a larger range of possible operating temperatures, exacerbating the thermal cycling problem. Also, the chip reliability quantification process does not include and represent the effects of small scale thermal cycles. A good number of in-field chip failures are attributed to the consequences of these. Thus, it is imperative to include their effects into the processor voltage and frequency selection process. Our work develops an integrated processor thermal and performance management technique centered on novel polynomial time scheduling algorithms that lead to lowering of thermal cycles in soft real time environments. Our technique leverages application awareness and runtime monitoring for improving chip lifetime, while achieving considerable energy savings. We show that a significant reduction in thermal cycles and peaks is possible, leading to longer chip life expectations.","PeriodicalId":7046,"journal":{"name":"ACM SIGOPS Oper. Syst.

For such applications, lack of availability, reliability, or responsiveness can lead to extensive losses. For instance, on June 29 2010, Amazon.com experienced three hours of intermittent performance problems as the normally reliable website took minutes to load items, and searches came back without product links. Customers were also unable to place orders. Based on their 2010 quarterly revenues, such downtime could cost Amazon up to $1.75 million per hour, thus making rapid problem resolution critical to its business. In another serious incident, on July 7, 2010, DBS bank in Singapore suffered a 7-hour outage which crippled its Internet banking systems, and disrupted other consumer banking services, including automated teller machines, credit card and NETS payments. The cascading failure occurred due to a procedural error while replacing a faulty component in one of the bank’s storage systems that was connected to its main computers. The high-cost of downtime in large-scale distributed systems drives the need for troubleshooting tools that can quickly detect problems and point system administrators to potential solutions. The increasing size and complexity of enterprise applications, coupled with the large scale of data centers in which they operate, make troubleshooting extremely challenging. Problems can arise due to a large variety of root-causes because of the complex interactions between hardware and software systems. The large volume of monitoring data available in these systems can obscure the root-cause of these problems. Lastly, the multi-tier nature of applications composed of entirely different subsystems man-","PeriodicalId":7046,"journal":{"name":"ACM SIGOPS Oper. Syst.
