Distributed heterogeneous computing environment based on the DIRAC software was established in the Laboratory of Information Technologies (LIT). This environment includes Tier1 and Tier2 clusters, the Govorun supercomputer, the NICA cluster, the DDC cluster, cloud resources from JINR member states, the UNAM cluster in Mexico, the IMDT cluster in Mongolia, and others. To integrate cloud resources, a new software toolkit was developed, enabling direct integration with OpenNebula-based clouds. To improve the efficiency of the deployed environment, task monitoring and data transfer methods have been developed and implemented. A fundamentally new approach to analyzing large task batches has been introduced, allowing for the analysis of hundreds of thousands of tasks and identifying inefficiently operating resources. A methodology for organizing experimental data processing has been developed and proven effective in processing data from the 8th run of the BM@N experiment. The implemented infrastructure has been used to address computational tasks for the MPD, BM@N, and SPD experiments. In total, over 3.5 million tasks have been successfully executed, with an average runtime of 8 hours. Information on the seminar and the link to connect are available at Indico.
