Latin America Maintains Its Presence in the TOP500 Announced at ISC High Performance 2025
During the latest edition of the ISC High Performance conference (ISC 2025), held from June 10 to 13 at the Congress Center Hamburg, the highly anticipated update of the TOP500 was unveiled. This international ranking highlights the most powerful supercomputers in the world. Latin America reaffirmed its presence on the list through the contributions of Argentina and Brazil, which continue to establish themselves as regional leaders in high-performance computing (HPC) infrastructure.
Argentina Holds Strong with Clementina XXI
Argentina retained its position in the TOP500 with the Clementina XXI supercomputer, a Lenovo-developed machine ranked 232nd. This system is installed at the Servicio Meteorológico Nacional (SMN) and is part of a national initiative to strengthen capabilities in climate forecasting and environmental modeling.
This supercomputer serves as a critical asset for climate science in the region, enabling progress in complex simulations, high-resolution weather analysis, and mitigation strategies in the face of climate change.
Brazil Expands Its Regional Leadership
Brazil, for its part, continues to strengthen its regional leadership as the Latin American country with the highest number of entries in the TOP500. In the previous list, published in November 2024, Brazil increased its total to nine classified supercomputers, adding one more system compared to the earlier edition. This growth reflects the sustained investment by Petrobras, LNCC, and various academic and industrial laboratories.
Brazilian supercomputers range from GPU-accelerated DGX H100 clusters used for AI training to petascale x86 platforms. These developments illustrate the country’s sustained efforts to modernize its computing capabilities in areas such as health, genomics, energy, materials science, artificial intelligence, and data science.
Regional Momentum Toward Technological Sovereignty
The continued presence of Argentina and the growth of Brazil in the TOP500 not only demonstrate technical progress, but also reflect a shared strategic vision: building homegrown HPC capabilities as a key tool for sovereign development in science, innovation, and data-driven decision-making.
In the broader context of ISC 2025—where topics such as artificial intelligence, data center sustainability, and global cooperation were also addressed—Latin America presented itself as a region committed to strengthening its digital infrastructure and actively participating in the global conversation on the future of advanced computing.
