Divjak, who was attending a meeting of the Education, Youth, Culture and Sport Council, said that by joining the initiative, Croatia had the possibility to exchange experiences and cooperate in using the shared European infrastructure.
Vice-President Andrus Ansip, in charge of the single digital market, and Digital Economy and Society Commissioner Mariya Gabriel welcomed Croatia's signing the declaration, noting that supercomputers were increasingly used in dealing with complex social challenges requiring great computer power, such as DNA sequencing, early diagnosis and treatment, creating climate models and cryptography.
The European declaration on high performance computers was launched in March 2017 and has so far been signed by 13 countries.
Before the Council meeting, Minister Divjak met with her Romanian and Finnish counterparts.
These two countries, along with Croatia make up the so-called presidential troika - the three countries which will chair the EU one after another and which work together on the presidency programme. Romania and Finland will preside over the EU in 2019 and Croatia in the first half of 2020.
"We have begun with preparations early enough and we have discussed possible topics for our presidency. This is very important to us, not only because of alignment and operational matters but also so that we prepare on time not only for what interests the EC but what interests us too," Divjak said.
She added that a topic of interest for Croatia was the brain-drain and the way the EU was approaching it.
As for her meeting with Finnish Education Minister Sanni Grahn-Laasonen, Divjak said that she had thanked Finland for reviewing Croatian curricular reform documents.
