Consistent and reliable grid computing - Infrastructure experiment has become one of the biggest components of the new outstanding achievements - confirmation that opened in 2012 boson with a mass of ~ 125 GeV/s2 really the Higgs boson, Perche measuring the decay probability B0s ? ? ? ? ? and receiving new restrictions on the record the existence of "new physics" beyond the Standard Model (SM). Specialized computer complex (VC) KIPT (T2 Centre T2_UA_KIPT) is an active element of this hierarchical infrastructure, working on her 2 - m "tier." The complex data takes a POT, and computing resources used to analyze these data and computer modeling experiment CMS. 2013, the complex was transferred to ~ 33 terabytes of data CMS, and the intensity of its use of computing resources was ~ 20 thousand kHEPspec - hours, or more than 60% of the corresponding total contribution of Ukraine in the world-wide grid - data infrastructure for LHC (WLCG) . Level of readiness to participate in the center of the CMS data processing for the year was ~ 90%, which is high enough quality indicator of the center. At the same time, the hardware parameters VC KIPT significantly inferior "nominal" T2-center grid - infrastructure CMS. In 2013, with funding from the National Academy of Sciences of Ukraine in the framework of the State target scientific - technical program implementation and use of the Grid - Technology (DTSNTP) for 2009 - 2013 was supposed to modernize the complex with an increase in its total performance computing nodes to 7.1 kHEPspec06 and data storage capacity up to 500 TB, thereby bringing T2_UA_KIPT Center settings to "nominal." In 2013, it was also a large amount of work on the physical analysis of experimental data with the WAC. In particular, the experiment CMS, resulting in the session 2010 - 2012 years, have been analyzed to search for SUSY - particles, the study of inclusive production of mesons in proton - proton collisions, and Drell-Yan process near Z - pole with working algorithms deconvolution mass spectra muon pairs. For these studies were used ~ 5000 CPU-hours of computing resources WLCG.
