Efficient communication for FPGA clusters

Abstract. Efficient communication between nodes is critical for achieving high performance in a computer cluster. Based on a dedicated interaccelerator network, we enhance this communication with advanced networking functions, such as broadcasting and priority routing. This work enables decoupling user applications from physical network implementations, improving overall communication efficiency and modularity. A performance model is introduced taking into account application and platform specific parameters. Experiments are performed for various network configurations and application patterns. The results show up to a 55 % reduction of communication time when employing our approach
