As the number of people browsing the world-wide web increases explosively, workload of popular web servers also increases rapidly. A multicomputer system that was designed for I/O intensive applications has been found to be quite suitable for serving as a web server. The system is composed of multiple clusters of multiprocessors interconnected by an interconnection network. The interconnection network is an ATM-like cell-based switching network which can be restructured so that the system can be scaled up to meet the increasing demands of web service. It is also found that the multicomputer system can support video streams e ectively. Design of the system as well as porting of web servers on to it will be discussed in this paper.
