Research

Research in the parallel computing group is focused on solving compute and memory intensive problems in high speed network processing, data intensive computing and high performance computing. Examples are virtualized packet classification and deep packet inspection for the Internet backbone, large-scale pattern matching, belief propagation and graph inference. We investigate new algorithms and algorithm-architecture mapping to optimize our solutions on parallel and/or heterogeneous architectures including Field-Programmable Gate Arrays (FPGA), general purpose multi-core (CPU) and graphics (GPU) processors.
