High-Performance Networking

Our research in high-performance networking addresses the communication needs of Grand Challenge applications over a wide range of environments: wide-area network (WAN) in support of computational grids and local-area network (LAN) and system-area network(SAN) in support of network of workstations and clusters.

While the high-performance computing (HPC) community generally groups clusters and grids together as commodity supercomputing infrastructures, the networking aspects of clusters and grids are fundamentally different. In clusters, the primary communication bottleneck is the host-interface bottleneck, whereas in grids, the bottlenecks are adaptation bottlenecks; in particular, flow control and congestion control. To address these problems, we offer a set of general solutions for each of these environments.
