15th Call for Proposals for Production Projects

Deadline: 8 September 2023


State-of-the-art supercomputing capabilities to the Greek and international scientific and research communities.


The  system targets a broad range of applications and scientific domains such as: Computational Sciences, Earth Sciences etc.


The system comprises 426 nodes, equipped with latest HPC oriented x86_64 CPU technologies, providing power efficiency and low footprint.


The projected sustained performance of the system is  ~180 TFlop per second.

Center of Gravity

Will become an important center of gravity for technical computing in Greece and South East Europe.


The system will foster international collaboration and resource sharing in Europe and beyond

The National Infrastructures for Research and Technology S.A. (GRNET S.A.) pioneers in the field of supercomputing infrastructures, by operating Greece’s first national high-performance computing system (HPC) to support large-scale scientific applications. The supply and installation of the new system was carried by COSMOS Business Systems in collaboration with IBM, after an open international tender,  supervised by GRNET. The new infrastructure is expected to play an important role in the development and promotion of scientific research in the country and in South East Europe.

The system is based on IBM’s NeXtScale platform, incorporating the latest generation of, Intel ® Xeon ® E5 v2 processors, (Ivy Bridge) and it will provide computational power that reaches 180TFlops (trillion floating point operations per second). With a total of 426 compute nodes, it will offer more than 8500 processor cores (CPU cores) interconnected through FDR Infiniband network, a technology offering very low latency and high bandwidth. In addition, the system will offer about 1 Petabyte (quadrillion bytes) of storage, based on the IBM General Parallel File System (GPFS). The system software will allow developing and running scientific applications and will provide several pre-installed compilers, scientific libraries and popular scientific application suites.

The system will be integrated into the European supercomputing ecosystem, aspiring to be listed in the 500 most powerful super-computers in the world, enhancing Greece’s participation in the pan European infrastructure PRACE (Partnership for Advanced Computing in Europe).
The national HPC system is expected to empower the Greek Scientific Community by meeting the needs of Greek users in multiple scientific fields, strengthening their ability to access the PRACE infrastructure. Computational Chemistry, Physics, Biology, Biomedicine, Meteorology, Seismology, Computational Engineering, Materials Science and Earth Observation are among others, indicative scientific fields that heavily rely on the use of modern supercomputing infrastructures.

The national supercomputing infrastructure was developed in the context of the “PRACE-GR – Developing National Supercomputing Infrastructure and Related Services for the Greek Research and Academic Community” project, which is co-funded by the Operational Program “Attica” Priority Axis “03 – Improving Competitiveness, Innovation and Digital Convergence” and the European Regional Development Fund (ERDF).
