My research focuses on interconnection networks, the networks which
traditionally connect shared-memory and message-passing multiprocessor systems,
but have recently been deployed in a wide array of communication systems (I/O
interconnect, Internet routers, high-speed LANs, storage networks, on-chip
networks). In these systems, the demand for bandwidth is fast overwhelming the
limits of bus-based and crossbar-based fabrics and interconnection networks
have surfaced as a viable alternative.
The performance of interconnection networks is critical as it significantly
affects the performance of the overall system. In a multiprocessor system, a
high-performance network reduces the cost of communication, encourages
fine-grain parallelization, and improves application speedup. As the fabric
connecting line cards within an Internet router, a high-performance
interconnection network fabric enables a router to scale effectively, handling
hundreds of terabits per second.
In recent years, I have explored and proposed flow control and
micro-architectural techniques for extending interconnection network
performance. Future interconnection network designers will have to continue
pushing the performance envelope while taking into account the challenges
presented by technology scaling and the disparate requirements of the many
applications. These challenges warrant novel architectures and our research
aims to uncover relevant challenges and explore techniques to address them
effectively.
