Use of Distributed System CHARM at U70 Neutron Beam Experiments

The distributed system CHARM [1] for data processing and analysis in particles physics experiments is advanced. An eective solution of a two-uniform task of processing great volumes of the information and support of high-speed computing processes is realized on the basis of an inhomogeneous computer platform. The scheme of the computer platform is shown on the gure: Fig.1: The structure of computer platform CHARM-2003 system At some decrease in the level of protecting the resources shown in the top part of the gure, and use of elements of infrastructure GRID, developed in LIT JINR, the conguration of the computer platform gets signicantly simpler (Fig.2). The created system provides processing big data sets (TerraByte range) due to integration of the mass centralized memory with local le servers of cooperating laboratories. High eciency is achieved, in particular, due to automatic algorithms of parallel processing developed and realized on the basis of the theory of heterogeneous multilinear systems of queuing. The control system of parallel processing provides dispatching tasks as well as interrelation between the processes of solving of one task
