R-CCS Cafe 第156回

A Field programmable gate array (FPGA) is a reconfigurable device on which we can implement arbitrary circuits repeatedly. By optimal implementation and stream processing, FPGA-based computing achieves both high computing performance and high power efficiency. To further improve the performance, it is necessary to realize an FPGA cluster with multiple nodes. We have developed a directly connected FPGA cluster and communication platform for the cluster. In this talk, I introduce the design and structure of the FPGA cluster and how to communicate in the cluster. I also explain the communication modules and actual data movement on the FPGA cluster. Finally, I shows that the proposed platform achieves fast and flexible communication for various application on FPGAs.
