Title: Cluster Interconnects Crystal Ball: which will win in 2006?
Description: The architectures and technologies used for cluster interconnection are in continual flux. Recently a number of emerging technologies have begun vying for a spot at the cluster interconnect feast. Infiniband specifies new technology at many transport levels, including a new user interface. The advantages of SCSI and Ethernet are being combined in the iSCSI protocol. Optics has begun to play a role in clusters. The latencies of some interconnects are getting low enough to consider support of NUMA traffic.
Today's gigabit and multi-gigabit Ethernet and Fibre Channel solutions give these technologies an evolutionary advantage over game-changing interconnects. Within the server, PCI-X and 3GIO are the anointed heirs to PCI. On the high end, proprietary interconnects such as Myrinet, GigaNet, and Quadrics are often employed, especially for supercomputer clusters.
Given this current plethora of cluster interconnects, what technologies---or combinations of such interconnects---are likely to be used in clusters in the 2006 time frame? And why? If you wish, you may create separate crystal-ball readings for low-end, mid-range, high-end, and supercomputer clusters. Or you may categorize your predictions according to other market delimiters, for instance based upon application.

Deadline for advance registration is March 25, 2002.
A large number of research groups from academia, industry, and research labs are currently engaged in the above research directions. The goal of this workshop is to bring together researchers and practitioners working in the areas of communication and architecture to discuss state-of-the-art solutions as well as future trends for designing scalable, high-performance, and cost-effective communication architectures for clusters.
The first workshop in this series (CAC '01) was held in conjunction with IPDPS '01 conference and it was very successful. CAC '02 workshop plans to continue the tradition of CAC '01.
