| Summary: | In order to meet the requirements of on-demand data sharing and real-time data stream transmission in Command Control and Simulation high-performance cluster systems, a high-speed interconnection mechanism based on Multi-hosts memory mapping is designed by using the native PCIe channel and the proposed one-way message queue. The interconnection mechanism provides three different protocols for transferring data, including inline, short, and long protocols. Combined with the PCIe Multi-hosts memory segment mapping method, it implements the functions of memory sharing, reflection memory, RDMA and other functions between the nodes. The proposal has the characteristics of low overhead, low latency, high bandwidth, etc., and can support the sharing and flow of batch data between local nodes in Command Control and Simulation systems. The final test results show that the proposed interconnection mechanism has high-speed data transmission capability, and the RDMA transmission rate can reach 9 000 MB/s with PCIe X16 lanes, and the data transmission delay can be effectively reduced. |
