Description of Research
The SMART Interconnects Group at USC, under the leadership of Dr. Pinkston, rigorously pursues research on technologies and techniques for achieving high-performance communication in parallel computer systems---massively parallel processor (MPP) as well as network of workstation (NOW) architectures. Our efforts have focused on two areas: (1) development of efficient, deadlock-free, adaptive, and dynamically reconfigurable network routing protocols and (2) design, modeling, and implementation of emerging optoelectronic interconnection network router architectures. Among some of our achievements, we have developed an intuitive model, a theoretical framework, and empirical techniques for characterizing network deadlocks; we have introduced the technique of progressive deadlock recovery-based routing; we have proposed a novel fully-adaptive optoelectronic network router architecture; and we have proposed a hybrid cache-coherence/network interconnect architecture based on optical technology.
