Abstract

In order to obtain diagnostic data with physical meaning, the acquired raw data must be processed through a series of physical formulas or processing algorithms. Some diagnostic data are acquired and processed by the diagnostic systems themselves. The data processing pro- grams are specific and usually run manually, and the processed results of the analytical data are stored in their local disk, which is unshared and unsafe. Thus, it is necessary to integrate all the specific process programs and build an automatic and unified data analysis system with shareable data storage. This paper introduces the design and implementation of the online analysis system. Based on the MDSplus event mechanism, this system deploys synchronous operations for differ- ent processing programs. According to the computational complexity and real-time requirements, combined with the programmability of parallel algorithms and hardware costs, the OpenMP par- allel processing technology is applied to the EAST analysis system, and significantly enhances the processing efficiency.
