最近的商用FPGA板具有巨大的计算资源和高带宽的板载存储器和网络端口，这扩大了FPGA集群在工业和学术领域的使用。然而，构建高效的多FPGA系统并不容易，因为开发FPGA集群的网络系统需要深入了解硬件和网络，以及网络设备的经济成本。图1所示为使用商用FPGA板构建的FPGA集群的典型架构。我们可以为FPGA集群采用两种可能的网络。一个是连接FPGA板上的外部端口的网络，我们称之为FPGA专用网络。另一个是连接安装FPGA板的CPU服务器的网络，我们称之为服务器网络。我们定量比较这两个网络的FPGA集群，专注于他们的性能与现实世界的应用。由于FPGA与网络之间的直接连接而无需通过中间设备，因此FPGA专用网络提供了低开销的高效通信。这种专用网络还能够为应用所需的通信模式提供最佳网络拓扑。另一方面，采用FPGA专用网络需要根据通信方式在FPGA上准备具体电路。FPGA专用网络的缺点之一是
Recent commercial FPGA boards have enormous computational resources and high-bandwidth on-board memory and network ports, which expands the use of FPGA clusters in industrial and academic fields. However, it is not easy to build an efficient multi-FPGA system because developing a network system of an FPGA cluster requires in-depth knowledge of hardware and networking, as well as economic costs for network devices. A typical architecture of an FPGA cluster built with commercially available FPGA boards is shown in Fig. 1. There are two possible networks we can employ for FPGA clusters. One is a network connecting the external ports on the FPGA boards, which we call an FPGA-dedicated network. The other is a network connecting the CPU servers installing FPGA boards, which we call a server network. We quantitatively compare these two networks of FPGA clusters, focusing on their performance with a real-world application. The FPGA-dedicated network provides efficient communication with low overhead due to the direct connection between FPGAs and the network without passing through intermediate devices. This dedicated network also enables having the optimal network topology for the communication patterns required by the application. On the other hand, the adoption of FPGA-dedicated networks needs to prepare specific circuits on the FPGA according to the communication method. One of the drawbacks of FPGA-dedicated networks is
