Description
The Baryonic Matter at the Nuclotron (BM@N) experiment [1] is first experiment at the NICA (Nuclotron-based Ion
Collider fAcility) [2], where runs with collection of experimental data have been performed. The software package BmnRoot [3]
is used both for simulation of setup operation and analysis of experimental data. Due to complexity of algorithms event
reconstruction is time-consuming and should be optimized to improve its performance [4].
Extended hotspot analysis has been performed of the simulation and new event reconstruction modules in the BmnRoot package.
The results of hotspot analysis are analyzed. Both algorithmic and high-performance optimizations
have been applied. Scalability and efficiency of optimized modules on simulated and experimental data are studied.
This work is supported by Russian Foundation for Basic Research grant 18-02-40104 mega.
