Supercomputer Frontier Models the Universe with Unprecedented Detail

/in /tarafından

A groundbreaking cosmic simulation has been achieved using the Frontier supercomputer, one of the most advanced computing systems in the world. This simulation offers an unprecedented level of detail in modeling the observable universe, incorporating not only gravitational forces but also complex interactions involving dark matter, gas, and plasma. The ability to simulate such intricate cosmic phenomena represents a major leap forward in our understanding of the universe’s large-scale structures and evolutionary processes.

The simulation was conducted as part of the U.S. Department of Energy’s Exascale Computing Project, which aims to push the boundaries of computational science. Using the Hardware/Hybrid Accelerated Cosmology Code (HACC), the research team at Oak Ridge National Laboratory (ORNL) leveraged Frontier’s immense processing power to run calculations at speeds nearly 300 times faster than previous cosmological models. This breakthrough showcases the potential of exascale computing in tackling some of the most complex problems in astrophysics.

A key component of this research was the application of hydrodynamic cosmology, which integrates dark matter and energy with traditional gravitational interactions. Previous simulations primarily focused on gravity’s role in shaping the cosmos, but the new model provides a more holistic view by incorporating additional physical factors. To achieve this, the researchers utilized 9,000 computing nodes, each equipped with AMD Instinct MI250X graphics processors, allowing for higher-resolution simulations than ever before.

The success of this simulation underscores the transformative impact of supercomputing on scientific discovery. By replicating the universe’s intricate processes with unparalleled accuracy, researchers can refine existing theories of cosmic evolution and gain deeper insights into fundamental astrophysical questions. As computational power continues to advance, future simulations may unlock even more mysteries about the formation and behavior of the universe on the grandest scales.

iGenius to Complete $1B Data Centre Project with Nvidia by Summer

/in /tarafından

Italian AI startup iGenius is on track to complete a $1 billion data centre project in southern Italy by the summer, utilizing Nvidia technology. The project, which will span five years, has prompted the company to extend its funding round from an initial target of 650 million euros. CEO Uljan Sharka shared that the new supercomputer built for the data centre will perform at an extraordinary rate, capable of executing 115 billion calculations per second. This marks a significant leap from Europe’s previous top supercomputers, which could handle only 0.5 billion calculations per second until last year.

The data centre will be powered by Nvidia’s advanced Blackwell chips, providing 35 times more computing power than their predecessors, while using 25 times less energy. The facility will house 80 of Nvidia’s most powerful servers, each containing 72 Blackwell chips. Southern Italy was chosen as the site for the project due to its surplus of renewable energy capacity, which will help meet the high power demands of the supercomputing operation.

iGenius, founded in 2016, is one of the few AI startups in Europe valued at over $1 billion, competing with other industry players such as France’s Mistral and Germany’s DeepL. The company recently launched Colosseum 355B, a large language model designed specifically for industries with stringent data protection needs, including finance, heavy industry, and government sectors. iGenius differentiates itself from competitors like OpenAI by providing open-source AI models for companies to run on their own infrastructure, allowing for greater control over sensitive data.
