Czech national e-infrastructure services for HEP

Abstract

Czech e-infrastructure project e-INFRA CZ is the only project for ICT services defined on the Road Map of the Czech Republic for Large Infrastructures for Research, Experimental Development and Innovations. It was created by 3 national e-infrastructures: CESNET, CERIT-SC and IT4Innovations. The project provides ICT services mostly for Czech universities and research institutions. High energy physics projects belong to the most demanding users in terms of network, computing and storage capacities. We will describe usage of these three main categories for several HEP and astroparticle physics projects in which Czech institutions are involved. But not only these most visible services are provided. Other services like security CSIRT team, backup solutions, virtualization platform, identity management, Jupyter notebooks, electronic logbook and user support system are extensively used. Many concrete examples will be given on e-INFRA services usage by the Czech WLCG Tier-2 center. We will also present the important role of the e-INFRA project as a national coordinator of international activities in the grid computing (EGI), open science solutions (EOSC) or high-performance computing (EuroHPC).
