Sofia Hosts Eastern Europe’s Leading Supercomputer at Tech Park

In a significant boost to Bulgaria’s tech infrastructure, the country has officially received Eastern Europe’s most powerful supercomputer. Delivered and assembled at Sofia Tech Park, the machine is based on Atos’ BullSequana XH2000 architecture and is capable of performing over 6 petaFLOPS — or 6 quadrillion calculations per second.

The supercomputer is part of the EuroHPC Joint Undertaking (JU), a pan-European initiative to develop world-class high-performance computing capabilities across EU member states. Bulgaria’s entry into this elite infrastructure circle is co-funded by EuroHPC JU and the Republic of Bulgaria, with a joint investment of €11.5 million.

This system will support scientific, public, and industrial research in diverse fields, including biotech, quantum chemistry, personalized medicine, bioengineering, AI, meteorology, and climate science. Crucially, it also strengthens Europe’s preparedness in health-related challenges — with supercomputers having been pivotal in COVID-19 vaccine development.

Leadership voices from Atos, EuroHPC JU, and Sofia Tech Park emphasize that this deployment marks a leap forward in regional collaboration, data sovereignty, and skills development. Peter Statev, Chairman of the Supervisory Board at Sofia Tech Park, highlighted the project’s potential to foster deeper partnerships between academia, industry, and the state — as well as to train a new generation of HPC specialists.

The Bulgarian supercomputer will operate alongside systems in Luxembourg, Slovenia, the Czech Republic, and Portugal, forming a distributed European HPC network.

By hosting this infrastructure, Bulgaria signals not just technical readiness but also strategic ambition — placing itself at the forefront of data-driven innovation in Eastern Europe.
