KM3NeT is a European research infrastructure project, which is currently under construction
at two locations in the Mediterranean Sea. The project aims to detect the neutrinos in the
energy range from a few GeV up to a few PeV with two detectors: ORCA (Oscillation Research
with Cosmics in the Abyss) for low energy (>GeV) and ARCA (Astroparticle Research with
Cosmics in the Abyss) for high energy (>TeV) neutrinos. A multi-level KM3NeT computing
model is necessary to acquire, process and analyse the large amount (up to 1Tb/s) of data from
the deep-sea detectors. The computing model is similar to the LHC computing model, with
three computing levels (Tiers). In this framework Tier-2 level computing refers to the analysis of
processed data and Monde Carlo events at the level of the research groups of the collaboration.
This contribution presents the KM3NeT project, its computing model and focuses on the Tier-2
computing infrastructure installed at the Tbilisi State University
