Title: Argentina Boots Up Clementina XXI, One of the World’s Most Powerful Supercomputers


Argentina has made significant progress in the field of information technology with the introduction of Clementina XXI, a supercomputer that is among the most powerful in the world. The computing device, located at the computing center of Argentina’s National Meteorological Service (SMN), will not only enhance the country’s scientific and technological capabilities but also solidify its position in the global technology landscape.

Power and Capabilities:

Clementina XXI, valued at 1.74bn pesos (US$4.9mn), was purchased last year and offers a range of impressive features. With a capacity of 15.3 petaflops using GPU accelerators and 440 teraflops using CPU processors, the supercomputer ranks 82nd among the 500 most powerful computers in the world. It boasts 296 Intel Ponte Vecchio accelerators and 5,120 cores in the Intel Sapphire Rapids HBM processors. Additionally, Clementina XXI has a memory capacity of 1.66 petabytes and achieves a network speed of 400 Gbps for internal interconnection between its nodes.

Shared Usage and Potential:

The supercomputer will be utilized on a shared basis by members of Argentina’s national science and technology system. Among the various beneficiaries, the SMN will utilize 10% of Clementina XXI’s capacity for weather forecasting and analysis. This will significantly enhance the accuracy and timeliness of weather predictions, benefiting various sectors including agriculture, aviation, and disaster management.

Historical Significance:

Argentina has a long history in the field of information technology, dating back to the 1960s. However, despite having a consolidated scientific community, the country has never possessed a supercomputer that ranks among the world’s most powerful. Science and technology minister Daniel Filmus emphasizes the historical significance of Clementina XXI, stating that not only is it among the top 100 most powerful computers globally, but it also marks a new milestone for Argentina’s technological advancement.

Collaborative Efforts:

The acquisition of Clementina XXI was made possible through a joint plan involving the science and technology ministry, the defense ministry, the meteorological service, and research council Conicet. These collaborative efforts highlight the importance Argentina places on advancing its technological capabilities and ensuring its position as a global player in the field.


With the introduction of Clementina XXI, Argentina has taken a significant step forward in the development of its technological infrastructure. The supercomputer’s power and capabilities will undoubtedly benefit various sectors and improve the country’s scientific research and innovation. As Argentina continues to invest in its technological advancements, it is positioning itself as a leader in the global technology landscape and opening up new opportunities for growth and development.
