This talk will explore the issues faced by enterprises in managing the complexity of information technology as well as progress in emerging autonomic technologies to address them. The discussion will consider the balance between technology automation and IT processes and human interactions with the management of technology. Recent trends in system management architecture, tools, and standards w...

Autonomic computing (AC) is an intelligent computing approach that autonomously carries out robotic and interactive applications based on goaland inference-driven mechanisms. This chapter attempts to explore the theoretical foundations and technical paradigms of AC. It reviews the historical development that leads to the transition from imperative computing to AC. It surveys transdisciplinary t...

The last three decades proved Moore’s Law. We witnessed an exponential increase in processing power, memory capacity and communication bandwidth and we expect this increase to continue for at least another decade. The effect is a growing complexity of computer systems and the need for highly qualified administrators. The question must be posed how computer systems can be managed in future if we...

Ubiquitous computing envisions a habitat where the abundance of mobile devices, services and applications allows the physical and virtual worlds to become seamlessly merged. Users in such a habitat can access their applications and data anywhere and anytime, and perform everyday tasks with greater ease. Applications are not bound to any single device but migrate with the user across different e...

Context-aware software provides adapted services to users or other software components. On the other hand, Autonomic Pervasive Computing uses context to reduce the complexity of pervasive system utilization, management and maintenance. This paper describes two context-awareness models, the macro and micro approaches, that define and integrate contextual views of individual pervasive components ...

We discuss a group protocol which supports applications with group communication service when QoS supported by networks or required by applications is changed. An autonomic group protocol is realized by cooperation of multiple autonomous agents. Each agent autonomously takes a class of each protocol function to support only and all QoS required by applications. Classes taken by an agent are req...

The trend toward larger high-performance computing (HPC) systems is leading to an increased demand for scalable software. However, HPC systems are also becoming more complex making the development and use of scalable software increasingly difficult. As a result, very few applications run effectively (or at all) at extreme scales. Furthermore, many application problems are manifested only at lar...
