BM@N Run 8 Data Processing on a Distributed Infrastructure with DIRAC

The BM@N 8th run using xenon ion beams was successfully completed in February 2023, resulting in approximately 600 million events. They were recorded in the form of around 31 000 files, with a combined size exceeding 400TB. To process all these data JINR DIRAC platform was chosen. The data reconstruction of BM@N 8th physics run was the first time DIRAC had been used for data reconstruction in JINR. A set of approaches, systems, and methods were developed during this campaign, which aid in reducing the efforts required for future data reconstructions at JINR.
