An initial deployment goal is specified using a declarative constraint language, expressing constraints over aspects such as component-host mappings and component interconnection topology. A constraint solver is used to find a configuration that satisfies the goal, and the configuration is deployed automatically. The deployed application is instrumented to allow subsequent autonomic management. If, during execution, the manager detects that the original goal is no longer being met, the satisfy/deploy process can be repeated automatically in order to generate a revised deployment that does meet the goal.","PeriodicalId":345031,"journal":{"name":"International Conference on Autonomic Computing, 2004.

One approach to reducing this cost is to develop storage systems that can configure and manage themselves. Unfortunately, our ability to develop such software has been hindered by a limited understanding of how workloads and storage systems interact. In earlier work we presented the design of the Distiller - our tool that automates the process of finding a workload's key performance-affecting attributes. In this paper, we distill three production workloads and show that the values of the chosen attributes contain information that will help self-configuring disk array to choose a reasonable prefetch length and RAID stripe unit size. We also discuss how the chosen attributes may help direct the development of algorithms that compute near-optimal prefetch lengths and stripe unit sizes.","PeriodicalId":345031,"journal":{"name":"International Conference on Autonomic Computing, 2004.

However this must be balanced with the need of resource owners to meet their goals in administering how users use their resources. This presents challenges of how to manage adaptive systems and how such management should be exercised by people, both average pervasive computing users and administrators of pervasive computing resources. This paper presents some of the issues involved in reconciling dynamic user-centric adaptation with the management of autonomic systems to meet high-level management policies. It discusses our architectural approach and presents some initial research results in addressing these issues.","PeriodicalId":345031,"journal":{"name":"International Conference on Autonomic Computing, 2004.

Too easily, a computer user or administrator can make a simple mistake and misconfigure a system, causing instabilities, unexpected behavior, and general unreliability. Bugs in software that changes these configurations, such as installers, only worsen the situation. A self-managing configuration system should be continuously monitoring itself for invalid settings, preventing the bugs from harming the system. Unfortunately, while there are many constraints which can differentiate between valid and invalid settings, few are explicitly written down, much less written down in a form usable by an automatic monitor. We propose an approach to automatically infer these correctness constraints based on samples of known good configurations. In this paper we present Glean, a system for analyzing the structure of configurations and automatically inferring four types of correctness constraints on that structure.","PeriodicalId":345031,"journal":{"name":"International Conference on Autonomic Computing, 2004.

As an alternative to fixed-size, dedicated clusters, we propose a dynamically-shared application cluster model based on virtual machines. The system is dubbed \"OnCall\" for the extra computing capacity that is always on call in case of traffic spikes. OnCall's approach to spike management relies on the use of an economically-efficient marketplace of cluster resources. OnCall works autonomically by allowing applications to trade computing capacity on a free market through the use of automated market policies; the appropriate applications are then automatically activated on the traded nodes. As demonstrated in our prototype implementation, OnCall allows applications to handle spikes while still maintaining inter-application performance isolation and providing useful resource guarantees to all applications on the cluster.","PeriodicalId":345031,"journal":{"name":"International Conference on Autonomic Computing, 2004.

We present a distributed architecture, implemented in a realistic prototype data center, that demonstrates how utility functions can enable a collection of autonomic elements to continually optimize the use of computational resources in a dynamic, heterogeneous environment. Broadly, the architecture is a two-level structure of independent autonomic elements that supports flexibility, modularity, and self-management. Individual autonomic elements manage application resource usage to optimize local service-level utility functions, and a global arbiter allocates resources among application environments based on resource-level utility functions obtained from the managers of the applications. We present empirical data that demonstrate the effectiveness of our utility function scheme in handling realistic, fluctuating Web-based transactional workloads running on a Linux cluster.","PeriodicalId":345031,"journal":{"name":"International Conference on Autonomic Computing, 2004.
