GRID (distributed computing) technology is the form of usage distributed computer resources when very large tasks are performed by using infrastructure of several countries. This technology is actively used in high energy physics, astrophysics, meteorology, climate change studies, biology, medicine and demand is increasing constantly.

In 2009 GRENA established the first GRID cluster in Georgia, which is incorporated in the European GRID Infrastructure (EGI).

In 2013 in cooperation of Tbilisi State University GRID Certification Authority (CA) was established which provides X.509 certificates for identification and insures secure environment for the computations. CA provides user, server and service certificates for researchers and systems involved in GRID activities.

GRENA enables researchers that have tasks (such as intensive scientific research calculations) requiring very large computational resources to use European GRID infrastructure.
