DESCRIPTION:Speakers: Sergei Nemnyugin (Saint-Petersburg State University)
 \nIn the BM@N (Baryon Matter at Nuclotron) experiment at NICA accelerator 
 complex in Joint institute for Nuclear Research (Dubna\, Russia) study of 
 collisions of isospin symmetric nuclei with fixed targets is performed [1]
 . Efficient software environment plays key role in the BM@N experimental p
 rogram. The BmnRoot software package is used for both simulation and event
  reconstruction of simulated and experimental data. Special attention is t
 o the BmnRoot performance optimization [2]. The present report is devoted 
 to performance optimization of the experimental data decoding module of th
 e BmnRoot software package. Most time-consuming hotspots of the decoder ha
 ve been localized. Vectorization of these hotspots improved performance of
  most time-consuming decoder functions by 1.25-2 times. As a consequence\,
  total time of execution is improved by 15-20%.  Quality assurance demonst
 rated correctness of optimization.\n\n1. D. Baranov\, M. Kapishin\, T. Mam
