CONET 97 DEVELOPMENT OF THE NETWORKING, INFORMATION AND COMPUTING INFRASTRUCTURE AT JINR CONET 97, Release 5, 1997

The purpose of the Project is to create a unified networking, information and computing environment for JINR, its international collaborants and member-state institutes on the base of the development of the networking, information and computing infrastructure at JINR in accordance with the needs of the research programs, up-to-date requirements on the individual working conditions for the scientists as well as free access to the world information and computing resources The purpose of the Project is to create a unified networking, information and computing environment for JINR, its international collaborants and member-state institutes on the base of the development of the networking, information and computing infrastructure at JINR in accordance with the needs of the research programs, up-to-date requirements on the individual working conditions for the scientists as well as free access to the world information and computing resources.

Tasks and Problems to be Solved at JINR International Collaboration Telecommunication Information Remote Access

To expect that JINR scientists will work exclusively at those institutes running the necessary computing technique - means the setting of JINR

In any case the exclusive use of the computing techniques of other institutes for research underway at JINR requires a sufficient increase of the throughput and reliability of the communication channels and means a unimaginable total dependence of JINR on providers and collaborating institutes

The participation in international collaborations on equal rights and duties requires a definite level of communication channels computing technique information resources at least on a mean international level

CHEP’97 has shown that the discussion on two data-handling models for future experiments - centralized data-handling and distributed data-handling led to the second model, nevertheless a lot of open questions still remaining. This is an additional argument in favour of the constant development of the JINR computing and network infrastructure.

JINR - a potential regional centre for data-handling on future experiments in East-Europe

To remain a serious partner within the international collaboration, it is necessary not to stand on the sideline of the permanent world-wide process of informatization. The level of computing and communication techniques in the future will become one of the most significant criteria, defining the main level of a scientific institution and its attraction. Main speculations:

Recent years have shown that JINR does not have the necessary resources for an adequate development of the computing and network infrastructure at its disposal. As a consequence some of JINR Laboratories make available parts of the resources, assigned to their research projects for specific computing needs. Obviously, this is good for the front-end technique but a wrong way for solving the main informatization problem, adding extra problems in the realization of a common technical policy in this field.
