The Taurus Environmental Information Management System, or TEIMS, system manages collaborative tasks, site characterization, modeling, risk assessment, decision support, operations tracking, compliance monitoring, and regulatory reporting for the Environmental Restoration Department. TEIMS also monitors LLNL’s performance in applying environmental technologies to the Department of Energy/National Nuclear Security Administration long-term stewardship program.
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.

LLNL’s Computing Directorate will descend upon the 2019 Supercomputing Conference. Find us at tutorials, workshops, panels, poster/paper sessions (with a Best Paper finalist), and the Job Fair.
This year’s event included quick presentations on a range of topics, deep dives, a keynote speaker, and a panel discussion dedicated to the onboarding process.
Lawrence Livermore heads to the ISC High Performance Conference (ISC19) in Frankfurt, Germany, on June 16–20. The event will draw more than 3,500 participants from the research and commercial communities, and 160 exhibitors will share the latest technology and products of interest to HPC developers and users.
