Cerio's Rockport Ethernet Fabric moves packet switching into endpoint cards connected through a passive optical SHFL interconnect. NC1225 cards provide twelve 25 Gbps fabric links and multiple paths, while the host interface is 100 Gbps. rNOS handles discovery and routing and ANM supports monitoring. A Queen's University/Sandia study demonstrates path-aware MPI integration; application performance depends on topology and communication software.
