Description
The Data Plane Development Kit (DPDK) is a framework that enhances real-time communications by providing direct, high-speed access to network interfaces. This architecture centralizes acquisition and control in an HPC cluster, ensuring ultra-fast in-memory updates of all critical data, making it a viable choice for real-time feedback and machine control in particle accelerators.
This approach was chosen for Elettra 2.0 to enable pre-mortem beam dump mitigation, more detailed post-mortem inspection, advanced correlation analysis and the implementation of complex control schemes. Time-sensitive applications implemented in C code interact with Beam Position Monitors (BPM), Low-Level RF (LLRF), Beam Loss Monitors (BLM) and Magnetic Power Converters through simple memory read and write operations at megahertz rates, making the system competitive with high-level processing applications based on FPGA architectures.
This paper presents the system under test at Elettra, highlighting its architecture, performance, and integration, while demonstrating the successful implementation of Fast Orbit Feedback in parallel with turn-by-turn (TbT) data acquisition from twelve BPMs and an LLRF system.
