与当今使用的最复杂的 AO 系统相比,随着下一代极大望远镜 (ELT) 的出现,自适应光学实时控制 (AO RTC) 的需求大幅增加。 Green Flash 是一个正在进行的欧盟资助项目,正在研究 ELT 规模 AO RTC 的最佳架构,重点是 GPU 和多核 CPU 解决方案。 Intel Xeon Phi 系列 x86 CPU 是我们当前研究 CPU 技术以解决 ELT 规模 AO RTC 问题的重点。 Xeon Phi 采用英特尔众集成核心 (MIC) 架构构建,将 64 个通用 x86 CPU 核心整合到单个 CPU 封装中,并搭配大量片上高带宽 MCDRAM,具有许多当前技术的优点。当前一代 Xeon Phi 很容易与标准 Linux 操作系统以及所有工具和库兼容,并且作为标准插槽 CPU,它消除了先前 Xeon Phi 和其他加速器设备所需的额外数据传输带来的延迟。 Durham 自适应光学实时控制器 (DARC) 是一款免费提供、经过空中测试、完全模块化、基于 x86 CPU 的 AO RTC,非常适合作为我们研究 ELT 规模 AO RTC 性能的基础。我们与 Green Flash 项目合作,针对 ELT 规模 MCAO 提出了概念验证 AO RTC 系统,并考虑到 MAORY AO 系统的要求,在 Xeon Phi 硬件上使用优化的 DARC 来实现所需的性能。
With the next-generation of Extremely Large Telescopes (ELTs), the demands of adaptive optics real-time control (AO RTC) increase massively compared to the most complex AO systems in use today. Green Flash, an ongoing EU funded project, is investigating the optimal architecture for ELT scale AO RTC, with an emphasis on GPU and many core CPU solutions. The Intel Xeon Phi range of x86 CPUs is our current focus of investigation into CPU technologies to solve the ELT-scale AO RTC problem. Built using Intels Many Integrated Core (MIC) architecture incorporating 64 general purpose x86 CPU cores into a single CPU package paired with a large pool of on-chip high bandwidth MCDRAM, the Xeon Phi includes many of the advantages of current technologies. The current generation Xeon Phi is readily compatible with standard Linux operating systems and all of the tools and libraries, and as a standard socketed CPU it eliminates the latency introduced by the extra data transfers required for previous Xeon Phis and other accelerator devices. The Durham Adaptive Optics Real-time Controller (DARC) is a freely available, on-sky tested, fully modular, x86 CPU based AO RTC which which is ideally suited to be a basis for our investigation into ELT scale AO RTC performance. We present a proof of concept AO RTC system, in collaboration with the Green Flash project, for ELT scale MCAO, with the requirements of the MAORY AO system in mind, using an optimised DARC on Xeon Phi hardware to achieve the required performance.
