Ultra Mobile PCs present a new class of challenges for system designers since they are perceived to be versatile low power devices with the full functionality of larger handhelds/laptops. User experience of being ubiquitously connected and access to data anytime and anywhere is a fundamental requirement for this class of devices. However, access to data across wireless interfaces has a direct impact on battery life of such handheld devices. This paper presents detailed analysis of some Linux-based file systems and data access across wireless interfaces. Based on our observations and analysis, we make some key design recommendations for file systems in Linux-based ultra mobile PCs.
1. Overview of emerging class of Linux-based ultra mobile PCs, usage scenarios of anytime anywhere network/data access, design challenges from power and performance perspective
2. Review of analysis of file systems and research in power efficient file systems
3. Workload Analysis of Linux based ultra mobile PCs to evaluate file system performance over wireless interfaces and impact of new techniques like energy efficient file systems on battery life
4. File system design recommendations.
Attendees interested in design of Linux-based ultra mobile PCs will be interested. No in-depth knowledge of either networking or file systems is necessary to understand and benefit from this presentation.
