We constantly redefine technology's boundaries
Our hardware enables discovery-level science. The unique, world-class, balanced environment we’ve created at LLNL has helped usher in a new era of computing and will inspire the next level of technical innovation and scientific discovery.
Livermore Computing (LC) delivers multiple petaFLOP/s of compute power, massive shared parallel file systems, powerful data analysis platforms, and archival storage capable of storing hundreds of petabytes of data. We support a broad range of diverse and dynamic computing architectures—Blue Gene/Q; our Linux clusters, some of the largest on the planet (with Quartz being the biggest at 3251.4 teraFLOP/s); visualization, high-memory, and big data machines (such as Apache Hadoop servers); and homogeneous and heterogeneous core architectures. We continually explore new architectures and technologies.
Our advanced technology systems, such as Sierra, are used to run large-scale multiphysics codes in a production environment. Our advanced architecture systems explore technologies at scale with the intent that matured technology can be used as a basis to design future production resources.
We also specialize in deploying commodity technology systems. These systems leverage industry advances and open-source software standards to build, field, and integrate Linux clusters of various sizes.
LLNL has deployed dozens of very large Linux clusters since 2001. These clusters are modular in nature and provide a common programming model. Hardware components are carefully selected for performance, usability, manageability, and reliability, and are then integrated and supported using a strategy that evolved from practical experience.
We also deploy specialized visualization clusters and archival storage, as well as support and contribute to the development of the open-source Lustre parallel file systems. Lustre is mounted across multiple compute clusters and delivers high-performance, global access to data.
