A fast physics analysis framework has been developed based on SNiPER to process the increasingly large data sample collected by BESIII. In this framework, a reconstructed event data model with SmartRef is designed to improve the speed of Input/Output operations, and necessary physics analysis tools are migrated from BOSS to SNiPER. A real physics analysis e + e − → π + π − J/ψ is used to test the new framework, and achieves a factor of 10.3 improvement in Input/Output speed compared to BOSS. Further tests show that the improvement is mainly attributed to the new reconstructed event data model and the lazy-loading functionality provided by SmartRef.
First of all, three current server push modes are elaborated in this paper, including a detailed analysis and comparison. Due to a single server push mode is used by the current push frame, most application requirements can not be meet. Push techniques based on analytic hierarchy process is proposed in this paper, which selects optimal push mode in different situations by theory of operations research. This method not only improves server performance but also reduces server load. Finally, experimental results show that the proposed method is superior to other single mode.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
