On October 26, 2018, the DOE’s National Nuclear Security Administration, LLNL, and industry partners officially unveiled Sierra, one of the world’s fastest supercomputers, at a dedication ceremony to celebrate the system’s completion.
We’re creating an LLNL commodity cluster system software environment based on Linux/Open-Source. We use the Red Hat Enterprise Linux distribution, stripping out the modules we don’t need and adding and modifying components as required. Working in open source allows for important HPC customizations and builds in-house expertise. Having in-house software developers is necessary to quickly resolve problems (especially at scale) on our cutting-edge hardware without having to wait for the vendors. The environment includes Linux kernel modifications, cluster management tools, monitoring and failure detection, resource management, authentication and access control, and parallel file system software (detailed elsewhere). These clusters provide users with a production solution capable of running MPI jobs at scale. View content related to System Software.

Dozens of members of LLNL’s Computation Directorate will attend the 2018 Supercomputing Conference. The Laboratory’s presence includes tutorials, poster and paper sessions, and the Job Fair.
The all-day event featured discussion panels, lightning talks, and deep dives intended to bring the LLNL developer community together.
The second of three annual hackathons, the 2018 summer event showed that all ideas are welcome.
