摘要

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.
