Accelerating Parallel Sort on Tightly-Coupled FPGAs enabled by Onboard Si-Photonics Transceivers

We illustrate a case for a tightly-coupled lightweight fully-connected inter-FPGA optical network with Si-photonics transceivers. Counting sort of in-memory column-oriented data using eight custom FPGA cards can be 5.3 times faster than that with eight CPU-servers.
