Information × Registration Number 0211U006567, 0110U003917 , R & D reports Title Support and development of the NSC KIPT Т2-center of the CMS Grid infrastructure within the Worldwide LHC Grid (WLCG) popup.stage_title Head Levchuk Leonid Guennadievich, Кандидат фізико-математичних наук Registration Date 29-04-2011 Organization National Science Center "Kharkiv Institute of Physics and Technology popup.description2 The computer complex (CC) status NSC KIPT as one of the most stable and reliable Т2-center grid-infrastructures of experiment CMS it is confirmed after start LHC. It is reached in the conditions of restricted computing and disk resources of a complex and not enough wide channel of its exterior communication. Result the decision of a manual of grid-infrastructure CMS Т2-center T2_UA_KIPT with one of research and development sub dividings of experiment (data analysis group "Electroweak") began to associate and to allocate on CC NSC KIPT a part of the data about the LHC for their further analysis participants of experiment CMS. It has been completely prepared basis for hardware upgrade of a complex with approach of its parameters for requirements of grid-infrastructure CMS. According to growing requirements CMS to quality of a data interchange operations on certification of communication paths of center T2_UA_KIPT with other centers of a grid-infrastructure of experiment have been continued. Rerouting of distant exterior communication of complex T2_UA_KIPT has allowed to complete successfully certification of all 8 channels of arrival of the information on CC NSC KIPT from Т1-centers CMS. Was as a row of transmission channels from T2_UA_KIPT in others Т2-centers CMS is certificated. Certification 3 new (in addition to two which already have been certificated earlier) "reverse" transmission channels from T2_UA_KIPT on Т1-sites experiment is Besides successfully fulfilled. It is received experience of handling of the experimental information about the LHC which collects in experiment CMS and it is divided on its grid-infrastructure. For the first data samplings received at December, 2009 at energy of proton concussions 900 GeV, it is selected events with creation K0S-mezonov. It is fulfilled as the data analysis, received in the session of measurements begun in 2010 at energy of proton concussions 7 TeV. In appropriate data samplings it is selected and analyzed events with a birth single Z0-bozonov and their decays on muon pairs. For the analysis of the real data and as for computer simulation program complex CMSSW which provides, on the one hand, reconstruction of events is used, and from another - effective information access methods about regenerated objects (electrons, muons, adron streams, etc.). Calculations were fulfilled far off, in structures the LHC-GRID (WLCG), using packet CRAB developed in experiment CMS for a universalization of procedure reversal to the data and simplification of access to computing resources WLCG.
