Cielo: NNSA Capability Supercomputer
The National Nuclear Security Administration (NNSA) Advanced Simulation and Computing (ASC) Program Cielo computing system is the next-generation tri-Lab capability platform beyond the Purple system, which was retired in 2010. Cielo represents a 6x to 10x increase in the classified compute capability for NNSA over its predecessor. Cielo will be used by scientists at three national laboratories: Los Alamos (LANL), Sandia (SNL), and Lawrence Livermore (LLNL), to solve our nation's most demanding stockpile stewardship problems; that is, the large-scale application problems at the edge of our understanding of weapon physics. This fully functional, petascale system serves a diverse scientific and engineering workload. Cielo provides a robust code development and production environment scaled to meet or exceed the workload requirements.
Cielo’s capabilities were designed and developed jointly by LANL and SNL under the Advanced Computing at Extreme Scale (ACES) partnership. The system is physically located at LANL in the Nicholas Metropolis Center for Modeling and Simulation. The facility is designed to scale with the increasingly powerful compute resources to deliver the required end-to-end services for users. Within the center are networking, archival storage, visualization servers, global file systems, and system software, all enhanced to support Cielo’s size and architecture. The ACES partnership is responsible for the support of Cielo, including interactions with the vendor.
