The supercomputer El Dorado, developed by Sandia National Laboratories, has been ranked as the twentieth fastest in the world on the Top500 list published during the Supercomputing Conference 2024 in Atlanta. Although on a smaller scale, El Dorado shares the same architecture as El Capitan, the supercomputer at Lawrence Livermore National Laboratory, which leads the ranking as the fastest in the world.
A Key Advancement for Nuclear Security
El Dorado and El Capitan are part of the first class-leading exascale systems designed to support the mission of maintaining the nuclear arsenal of the National Nuclear Security Administration (NNSA) of the United States. According to Andrew Younge, supercomputing manager at Sandia, El Dorado is designed as an application readiness system, allowing for the development, testing, and validation of codes prior to their implementation on El Capitan.
“El Dorado acts as a massive access platform to prepare our engineering and science codes,” explained Younge. Additionally, it is anticipated that this system will also provide production cycles for Sandia laboratories and enable exploration of new workflows in experimental research and development in high-performance computing.
State-of-the-Art Technology
El Dorado utilizes cutting-edge technology, including the high-speed Slingshot network, developed by Cray, which facilitates data transfer at exceptional speeds. Kevin Stroup, another computing manager at Sandia, highlighted the direct liquid cooling system of the computing nodes, which efficiently dissipates heat generated through liquid-filled heat sinks. “Without this system, operating a machine of this caliber would be virtually impossible due to the heat produced,” he stated.
The supercomputer, designed and built by Hewlett Packard Enterprise, is an EX4000 model from the Cray line. It consists of three computing blade cabinets containing a total of 384 MI-300A nodes, an accelerated processing unit (APU) developed by AMD that combines CPU and GPU on a single chip.
A Tool for Advanced Simulation
El Dorado positions itself as a key tool for the NNSA’s Advanced Simulation and Computing program, which supports nuclear security through high-fidelity simulations. This system will enable Sandia to conduct more experimental research and enhance the accuracy of its models and simulations in critical areas such as nuclear deterrence and global security.
Sandia: Leadership in Technological Innovation
Sandia National Laboratories, with primary facilities in Albuquerque (New Mexico) and Livermore (California), are recognized for their contributions to the security and economic competitiveness of the United States. Operated by Honeywell International Inc. for the Department of Energy, these laboratories have responsibilities in energy technology, defense, and global security.
With the inclusion of El Dorado in the Top500, Sandia reaffirms its commitment to innovation in supercomputing, driving the development of technological solutions that strengthen national security and scientific advancement.
