Information × Registration Number 0222U003156, 0121U110718 , R & D reports Title Processing of data from the Large Hadron Collider at the NSC KIPT T2-center of the grid infrastructure of the CMS experiment in 2021 popup.stage_title Head Levchuk Leonid Н., Registration Date 19-02-2022 Organization National Science Center "Kharkiv Institute of Physics and Technology" popup.description2 In 2021, reliable operation was supported for the T2_UA_KIPT facility, which is the only Ukrainian tier-2 (T2) center of the grid infrastructure of the CMS experiment at the Large Hadron Collider (LHC). In accordance with the CMS requirements, a lot of works on facility’s upgrades were carried out. For the T2_UA_KIPT, the operation quality, which is determined by the readiness to participate in data processing, for 11 months of the year was 99.1%, which is the best performance among the CMS T2 centers. The usage of facility’s computing resources for this period exceeded 46 thousand kHEPspec06-hours, which is 100% (or 99%) of the total usage of Ukrainian grid (NGI_UA) resources by all virtual organizations (VO) associated with LHC (or all VO in general). To perform computations on physics analysis of the CMS data, ~36 CPU days (or ~60 wall-clock days) of WLCG grid resources were used. Operation was provided for a cloud service based on the OpenStack platform, which is registered in the 'Federated Cloud' EGI-infrastructure and demonstrates a satisfactory level of stability.
