The Deucalion supercomputer has officially been inaugurated in Portugal by the European High Performance Computing Joint Undertaking (EuroHPC JU).

Deucalion has a peak performance of more than 10 petaflops, and is based on Arm A64FX processors and Bull Sequana technology from Eviden (recently split from Atos).


The supercomputer was provided by Fujitsu Technology Solutions and is reportedly the first EuroHPC supercomputer to be based on Arm processors. Plans were first announced in February 2021.

The high performance computing (HPC) cluster will be used for research and development in meteorology and climate modeling, fluid dynamics and aerodynamics, and astrophysics and cosmology among other things.

Deucalion had a total budget of €20 million ($21.4m) provided by EuroHPC and the Portuguese Foundation for Science and Technology (FCT).

The HPC is housed at the University of Minho's Minho Advanced Computing Center in Guimaraes and was inaugurated by Portuguese Prime Minister Antonio Costa.

Madalena Alves, president of FCT, said: “The Deucalion supercomputer is capable of supporting over 200 projects annually and can multiply the national computing capacity by tenfold. High-performance computing generally comes with a high cost. By making this resource accessible to all researchers, institutions, and even companies, we aim to enhance the competitiveness of science and technology developed in Portugal."

Deucalion is the eighth supercomputer procured by the EuroHPC JU. Other supercomputers include LUMI in Finland, Leonardo in Italy, Vega in Slovenia, MeluXina in Luxembourg, Discoverer in Bulgaria, Karolina in Czechia, and MareNostrum5 in Spain. The JU is working on deploying two additional supercomputers: Jupiter, an exascale supercomputer in Germany, and Daedalus in Greece.
