Results of performance study of the BmnRoot software are presented. The BmnRoot software package plays crucial role in the Baryonic Matter at Nuclotron (BM@N) experiment of the NICA project. It is used for simulation and analysis of experimental data. Various approaches to performance optimization are discussed including algorithmic improvements and parallelization in simulation and reconstruction modules. Results of performance analysis are given and bottlenecks are localized. Results of efficiency and scalability studies for different approaches are also presented.
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.
