In CMS experiment on the Large Hadron Collider (LHC) in CERN for 2012. Selection of data by volume ~ 25 fbn-1 for energiya of collision of protons of 8 TEV is received. Stable and reliable the robot of the Large Hadron Collider (LHC), the detector CMS and as computing grid-infrastructure of experiment, became a basis, for outstanding achievements – detection of a new boson (the candidate for a role of a boson of Higgs) and receiving new restrictions on existence of "new physics" outside the Standard Model (SM). On the other hand, the fast increase in luminosity the LHC increases requirements to grid-infrastructure of CMS created for distributed data processing of this experiment. The specialized computer system (CS) of NSC KIPT (T2_UA_KIPT T2 center) is an active element of this hierarchical infrastructure, working at its 2nd "circle". The complex accepts for processing data about the LHC, and its computing resources are used for the analysis of these data, and as for computer modeling of experiment of CMS. For 2012 to a complex it was transferred more than 70 Tbyte of data of CMS, and intensity of use of its computing resources exceeded 10 thousand kHEPspec/hour, making more than 80% from the general annual contribution of Ukraine in the world grid-infrastructure for data processing about the LHC (WLCG). Average annual level of readiness of the center to participation in data processing of CMS exceeds 90% that is quite high rate of quality of work of the center. Together with it, on the CS NSC KIPT hardware parameters significantly concedes to "nominal" T2 center of grid-infrastructure of CMS. In 2012. Is provided to carry out complex modernization with increase in total efficiency of its computing knots to 5.5 kHEPspec06 and the volume of storage of data to 330 Tbyte, Having approached thereby T2_UA_KIPT center parameters to "nominal". The engineering infrastructure was prepared, the system of local monitoring complex robots is improved. But in connection with late (begun only in December) transfer of means under the relevant contracts the State treasury, to execute the planned modernization of CS NSC KIPT in full, by the time of preparation of this report it wasn't possible. In 2012. Works on processing of experimental information about the LHC are continued. For the purpose of search of a boson of Higgs of Standard model.
