Trends in the development of distributed computing and Big data technologies to support mega-projects
Distributed infrastructure for data processing and analysis of the experiments at the Large hadron Collider and the evolution of their development presented in the report. Problems of integration of different distributed computing architectures (grid, cloud, HPC) are analyzed on the basis of the experience of participation in many large-scale projects. Simulation of computer infrastructure for the mega-project of NICA held on the basis of parameters of the physical detectors and data processing scenarios. Computer infrastructure mega-project is developed on the basis of trends of development of information technologies.
