A Reconfigurable Optical Interconnect System for DSAG

High performance computing research is facing challenges and innovation on architecture is urgent. DSAG architecture is proposed and delivers "Architecture on Demand" feature. In DSAG, components in different catalogs are parted, while the ones in same catalog are congregated. This architecture can be enabled by optical interconnect and reconfigurable computing technology. Using advanced optical devices and enhanced reconfigurable computing devices (FPGA), we build a prototype system for DSAG. Optical interconnect can reach 16Gbps bandwidth; DDRAM interface is selected as host communication interface to match the bandwidth of optical channel; Reconfigurable logic and embedded processors are employed for flexible reconfiguration. The system is featured by high bandwidth, owerful, flexible.
