高能物理分布式数据获取架构的设计与实现
Design and Implementation of Distributed Data Acquisition Architecture in High Energy Physics
摘要
Abstract
The amount of experimental data generated in the large-scaled contemporary high energy physics experiments have increased dramatically, that places more stringent, complex and high-performance requirements on the data acquisition online processing software system. With the high-speed Internet and powerful process units, the data collection and processing capabilities of distributed online processing software have been significantly improved, making data acquisition targets of particle physics experiments have been achieved more efficiently. The framework of distributed online processing takes the charge of the control and management of multiple processes that running on the cluster, hardware and software configuration, status monitoring, information sharing and interaction in functional. Compared to distributed coordination services based on message delivery, the shared memory technology such as Redis simplifies the coordination among multiple processes in the system, achieves the final balance of lightweight CAP, and stores data acquisition information as a central database, which is a convenient, lightweight and practical solution for realizing the online processing framework. In some medium-scale high energy physics experimental computing cluster, it is reliable and stable for development, implementa-tion, and deployment.关键词
