Although commodity cluster computing based on very fast and inexpensive commodity processors are proliferating today, one of the prohibitive factors towards its large-scale deployment is the high cost of the network switching fabric in order to retain properly high bandwidth. We argue that, except for the most demanding applications, appropriate aggregation of inexpensive switches, with collective communication algorithms that utilize the characteristics of such networks, will accommodate a bulk of parallel applications, even those with substantial communication requirements. We present 3 techniques for implementing high-bandwidth collective communications in such a setting, and provide preliminary performance measurements that hint the effectiveness of our proposal. The technique can be extended to interconnect a set of clusters for implementing high-bandwidth Grid interconnect as well as replacing SAN for high-bandwidth I/O.
