Abstract The article addresses implementation of parallel event reconstruction in the BmnRoot framework that is used in the BM@N experiment at the NICA collider complex. The framework is based on the ROOT environment and FairRoot package. BmnRoot is used both for simulation and reconstruction of high-energy collision events and experimental data analysis. The reconstruction of the BM@N events requires a lot of data to process and takes a relatively long time. The paper presents the results of PROOF integration into the event reconstruction module of the BmnRoot framework and an assessment of the performance improvement on a multi-core processor.
