Modern experimental stands generate long-lasting and intense data streams. Limited computing resources of stands and increasing the accuracy requirements of algorithms make it impossible to provide a local processing. However, a high bandwidth optical lambda networks allows one to transfer calculations to remote supercomputers. It is extremely important to organize an efficient parallelism in all components of the distributed system. This paper considers a model of stream processing of experimental data and focuses on the use of high-speed fiber-optic long-distance data networks for communication of experimental stands with high-performance computing systems.
