Abstract :
FPGA accelerators are capable of improving computation and energy efficiency of many applications targeting a cluster of machines. In this work, we focus on an FPGA accelerated cluster system coupled with a wireless network. Comparing with conventional Ethernet based approaches, the proposed system with wireless network enables a light-weight and efficient method for the FPGA devices to exchange information directly. Customisable monitoring facilities are developed to support changing a distributed application dynamically at run time. The N-Body simulation application is used to demonstrate the effectiveness and potential of the proposed system. Experiments show that this approach can achieve up to 4.2 times improvement in latency. By applying the proposed inter-FPGA wireless network to the N-Body application, we achieve enhanced power efficiency while fulfilling thermal constraints in all nodes.
