Description
In 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 program. The BmnRoot software package is used for both simulation and event reconstruction of simulated and experimental data. Special attention is to the BmnRoot performance optimization [2]. The present report is devoted to performance optimization of the experimental data decoding module of the BmnRoot software package. Most time-consuming hotspots of the decoder have 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 demonstrated correctness of optimization.
