Abstract: The BES-III experiment at the Institute of High Energy Physics (Beijing, China) is aimed at the precision measurements in e$^{+}$e$^{–}$ annihilation in the energy range from 2.0 till 4.6 GeV. The world’s largest samples of J/psi and psi’ events and unique samples of XYZ data have been already collected. The expected increase of the data volume in the coming years required a significant evolution of the computing model, namely shift from a centralized data processing to a distributed one. This report summarizes a current design of the BES-III distributed computing system, some of key decisions and experience gained during 2 years of operations.
