Petascale Supercomputer Bulgaria

Initiative overview

The procurement includes the acquisition, delivery, installation and maintenance of a new petascale supercomputer co-owned by the EuroHPC JU and located in Sofia Tech Park, in Bulgaria.

Objectives:

To foster better science and enhance innovation in Europe by providing access to leading edge HPC infrastructures and services to a wide range of users from the research and scientific community as well as the industry and the public sector.

To develop top-of-the-range exascale supercomputers for processing big data, based on European technology.

Bulgaria currently has three HPC Supercomputer initiatives:

1) HEMUS Supercomputer 2023: An advanced computing facility integrated within Institute of Information and Communication Technologies’s infrastructure complex that delivers over 3 petaFLOPS of computing performance and provides 6.72 petabytes of data storage capacity. HEMUS is notable for its implementation of standardised data management practices that ensure research data is findable, accessible, interoperable, and reusable. The system was developed with support from the "Science and Education for Smart Growth" Operational programme.

2) Avitohol Supercomputer (in development): a specialised supercomputer operated by the National Center for High Performance and Distributed Calculations. The system's architecture is optimised for HPC applications. With 96 terabytes of storage capacity, Avitohol is expected to enhance Bulgaria's computational research infrastructure by providing essential resources for data-intensive scientific applications (National Centre for High Performance and Distributed Computing, n.d.[7]).

3) Discoverer Supercomputer (2021): a petascale supercomputer located in Sofia Tech Park that represents Bulgaria's first major investment in high-performance computing infrastructure. With performance exceeding 4.5 petaFLOPS, the system is specifically designed to support big data processing and AI applications (Discoverer) . Funding shared between EuroHPC (35%) and the Bulgarian government (65%)
