HPC Ecosystem and Competences in Bulgaria

In short, the current status of the HPC ecosystem in Bulgaria includes diverse modern hardware (including two supercomputers from the TOP500 list – Discoverer and HEMUS, as well as multiple HPC clusters), and extensive expertise in HPC and the adjacent fields. The competencies and expertise were acquired during a multitude of successful EU projects, as well as leadership and participation in high-profile national programmes and projects with industry/SMEs. Experience in negotiating and managing contracts with different sources of funding and for the use of both equipment and expertise has been gathered. In this paper, we discuss the new developments in the HPC Ecosystem, supported by the acquisition of the HEMUS supercomputer in 2023, as well as our design choices and optimization approaches.
