Description of the RI


Estonian Scientific  Computing Infrastructure (ETAIS) has been establised in 2011 to increase the competitiveness of the Estonian R&D in compute- and data-intensive fields through a modern computing infrastructure. The common infrastructure of compute clusters, storage and support allows researchers to collaborate in projects on local as well as on international level. ETAIS is the distributed infrastructure managed by the consortia of four national organisations: University of Tartu, Tallinn University of Technology, National Institute of Chemical Biology and Physics, Information Technology Foundation for Education (former Estonian Education and Research Network (EENet)).
