| Abstract | 针对超宽带及多波束接收系统海量天文信号实时高效传输与处理问题，对基于FPGA+GPU的主流终端设备软件系统进行了测试分析，超宽带接收设备要求终端系统软件能够在更宽带宽，更高时间、频率分辨率条件下，实现实时数据流传输与处理。结合大口径射电观测设备未来发展方向提出了利用高速并行环形缓冲区实现数据流缓存、基于GPU集群实现数据流实时处理、基于BeeGFS实现分布式并行数据存储，模块化构建射电天文信号传输管道软件的设计思路。 |
| Other Abstract | Aiming at problems of massive signals real-time transmission and processing in ultra-wideband and multi-beam receiving systems, we tested and analyzed the related software of the mainstream backend system based on FPGA+GPU. The ultra-wide band receiving equipment required the backend system software to be capable of wider bandwidth and higher time resolution and higher frequency resolution conditions, as well as the realization of real-time data stream transmission and processing. Combined with the future development direction of large aperture radio observation equipment, it was proposed to use high-speed parallel ring buffers to achieve data stream caching, GPU clusters to achieve data stream real-time processing, and distributed parallel data storage based on BeeGFS, modular construction of data stream transmission pipelines software design ideas. |
