Study of a real time feed-back system by the pipeline distributed parallel processing

开发了一种具有高速分布式流水线并行处理能力的软件框架。该框架由负责多核CPU中流水线并行处理的核心框架和通过网络连接PC服务器的外部框架组成，将并行处理扩展到PC集群。在Belle II实验的高级触发器测试平台上对该框架所提供的并行处理性能进行了测试，结果表明该框架能够达到预期的性能。该系统目前正在Belle II数据采集系统中实施。

A software framework with a capability of the high-speed distributed pipeline parallel processing is developed. The framework consists of the“core framework”, which takes care of the pipeline parallel processing in a multi-core CPU, and the outer framework to connect PC servers over network extending the parallel processing to the PC cluster. The parallel processing performance provided by the developed framework is studied using the High Level Trigger test bench of Belle II experiment, and it is confirmed that the framework can achieve the expected performance. The system is now being implemented in the Belle II data acquisition system.
