The paper considers the application of a software complex for data processing simulation incomputing systems. The BM@N experiment data storage and processing system of the NICA complexis used as a simulated infrastructure. Simulation is performed in order to obtain recommendations onthe organization of experimental data processing during a session with available allocated resources.The paper presents the results of simulating the processing of data that will be received during theBM@N experiment session, with several scenarios for distributing job flows across existingprocessing centers. In addition, some recommendations for organizing experimental data processingare proposed. The status of the work and future plans for the development of the software complex areformulated.
