Saturday August 23, 1997 - Tutorials

8:30 - 12:00 Infrared Wireless Communications

Joseph M. Kahn, University of California at Berkeley

The infrared medium is well-suited for high-speed wireless networking of portable computing devices. Directed and diffuse infrared systems, operating at bit rates up to 4 Mb/s, are now commercially available. We discuss current infrared standards, and present design strategies to achieve bit rates as high as 100 Mb/s. Topics addressed include: power-efficient link design, modulation/demodulation techniques, multipath propagation, and multiple-access techniques.

8:30 - 12:00 IPng: The Next-Generation Internet Protocol

Robert Hinden, Ipsilon

The Internet Engineering Task Force (IETF) has developed a new version of the Internet Protocol which is the core protocol in the Internet. IPng, also known as IP version 6 (IPv6) is designed to meet the challenge of Internet's continued exponential growth as well as adding important new features such as "plug and play" auto-configuration, strong security, and support for real-time traffic. This tutorial will include background on the why IPv6 was developed, detailed description of the IPv6 protocol, current status, and a frank discussion of whether it will be deployed.

8:30 - 12:00 The Implementation and Application of Beowulf Class PC Clusters

Please note change in time!

Thomas Sterling, California Institute of Technology and NASA Jet Propulsion Laboratory

The explosive emergence of Beowulf class PC clusters and other approaches to "piles of PCs" is offering new opportunities to achieving moderate to high end computing at unprecedented price performance. This tutorial describes the means and methodology for exploiting the ubiquitous availability of the hardware and software building blocks with their (almost) plug-and-play capability yield a "parts by dawn, processing by dusk" approach to clustered computing. Included are the a framework for considering the tradeoffs of alternative elements, the configuration and installation of ensembles, approaches to applications programming, and benchmarking results. Notes entitled "How to Build a Beowulf" will be distributed.

1:30 - 5:00 Virtual Interface Architecture

Chris Dodd, Intel Corporation

The Virtual Interface Architecture for System Area Networks is an industry-wide effort, lead by Intel, Microsoft, and Compaq, to standardize on a high performance A{I for cluster communication. This tutorial consists of two sessions. The first session will cover VI architectural concepts and services, how architecture meets the needs of scalable applciations, and the standard API syntax and semantics. The second session will offer perspectives of several leading organizations who will be among the first to have products that comply with the Virtual Interface Architecture specification.

1:30 - 5:00 Optical Interconnect Technologies: A Systems-Level Review The role of guided-wave and free-space optical interconnect technologies (OITs) within the intra-cabinet levels of the physical interconnection hierarchy will be discussed from (1) a wire-replacement perspective and (2) an architectural enabler perspective. Specifically, the impact of OITs on parallel processing execution models will be addressed. Also, current academic and industrial research efforts will be reviewed and areas in need of future research will be outlined.
