It imposes extremely severe constraints on the computer systems (CS) intended for the solution of this task. For processing and the analysis of data which are created in experiments the LHC, the branched out grid-infrastructure - "world LHC-grid" is created (WLCG) which element, CS NSC KIPT is. On the basis of which the computing system which in 2009 has been successfully certificated in CMS grid-infrastructure as the center of the 2nd circle of WLCG and shows a high level of quality and stability of work is created. By the time of start the LHC, within CMS experiment, it is created about 50 such centers in the different countries of the world. According to the kompjutingovyj CMS model, these centers bear all computing loading connected with modeling in experiment and as are responsible for placement of real data which turn out about the LHC. At this their computing resources are allocated for the analysis of these data, as external users of WLCG who participate in experiment, and local users of these CS. It demands providing an appropriate configuration of the elements WLCG on CS hubs and reliable work, both all grid-services, and the specialized software for reconstruction and the analysis of the events registered by the CMS detector. Using created CS and the WLCG resources in 2009 work on studying of analysis algorithms of data of CMS for the purpose of identification of a massive boson of Higgs, and as allocation of events with the birth of lonely Z0-bosons, in the conditions of rather small integrated luminosity the LHC has been continued. CS NSC KIPT participated in large-scale checks of grid-infrastructure of experiment of CMS which were led before start the LHC. To start CS NSC KIPT LHC remains operating element WLCG unique in Ukraine, namely, the unique T2-center of grid-infrastructure of experiments the LHC.
