Creation of the Grid-Site and Its Integration into the ATLAS Computing

Abstract

Modern information technologies offer various solutions that allow us, on a global scale, to combine heterogeneous information and computing resources into a single whole, to solve common problems. One such solution is GRID technologies. The GRID concept gives an understanding of how to combine heterogeneous computing resources, such as personal computers, computing clusters, supercomputers. Today, GRID technologies are widely used to solve problems in various scientific fields, such as high-energy physics and biophysics, genetics, microbiology and medicine, robotics and aircraft engineering, etc. The main tool of GRID technologies that can combine heterogeneous resources is the creation grid site. The grid site is a specific set of components interconnected by a number of tasks, namely, to receive and transmit, process and store the received data. To create and integrate a grid site into the global heterogeneous computing infrastructure, its components must strictly comply with the requirements that apply to grid sites from such international experiments as ATLAS, CMC, ALICE, LHCb and others. One of the most important requirements is the relevance of the software components of the grid site, since the state of the grid site as a whole depends on the indicators of their functioning. All of the above international experiments, in real time, monitor the state of the grid sites of their pool for the effectiveness of the main components. This article, based on experience with grid sites of various configurations, shows the algorithm for creating and certifying the grid site “AZ-IFAN”, Institute of Physics, National Academy of Sciences of Azerbaijan, for the ATLAS computing (CERN).
