Autonomic Systems

An autonomic system is defined as self-configuring, self-optimizing, self-healing, and self-protecting. We implemented the Autonomic Cluster Management System (ACMS), a low overhead Java application designed to manage and load balance a cluster, while working at NASA GSFC. The ACMS is a mobile multi-agent system in which each agent is designed to fulfill a specific role. The agents collaborate and coordinate their activities in order to achieve system management goals. The ACMS is scalable and extensible to facilitate future development

Autonomic Cluster Management System (ACMS): A Demonstration of Autonomic Principles at Work

Cluster computing, whereby a large number of simple processors or nodes are combined together to apparently function as a single powerful computer, has emerged as a research area in its own right. The approach offers a relatively inexpensive means of achieving significant computational capabilities for high-performance computing applications, while simultaneously affording the ability to. increase that capability simply by adding more (inexpensive) processors. However, the task of manually managing and con.guring a cluster quickly becomes impossible as the cluster grows in size. Autonomic computing is a relatively new approach to managing complex systems that can potentially solve many of the problems inherent in cluster management. We describe the development of a prototype Automatic Cluster Management System (ACMS) that exploits autonomic properties in automating cluster management
