On the use of federal scientific telecommunication infrastructure for high performance computing

The article is devoted to the prospects for the development of scientific telecommunications infrastructure based on the new generation national research computer network (NRCN), formed by the integration of departmental scientific and educational networks RUNNet and RASNet. The new network' capabilities for combining supercomputer resources and providing barrier-free access to them are shown. Based on the generalized world experience, it has been shown that supercomputer infrastructures have special requirements for a telecommunication network for data transmission and the presence of a number of additional services. These requirements go far beyond the services of commercial telecom providers and, as a rule, can only be satisfied by the combined efforts of national scientific and educational networks. The key elements of the federal telecommunications infrastructure necessary for combining high-performance computing resources are considered: high-performance communication channels with a specified quality of service, their automatic allocation on demand and on schedule, trusted network environment, federated authentication and authorization, reliability and security, end-to-end monitoring of the data transmission path between end users. Based on the analysis of the life cycle of the supercomputer job migrating at the distributed network, the requirements for the NRCN telecommunications infrastructure and services based on it are formulated.
