In the first of three news features, LLNL-developed Flux software will contribute to the efficiency and effectiveness of the HPC leadership-class systems of tomorrow.
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. Be sure to follow LLNL Computing on Twitter with the #ISC19 hashtag.
When it comes to IT needs, a 6,500-employee national laboratory is effectively a small city. Computation’s enterprise computing–focused divisions provide technical support and customer service for LLNL’s vast inventory of desktop computing hardware/software, servers, mobile devices, as well as other IT services fulfilling Livermore’s requirements in communication, collaboration, and cyber security.
Bolstered by ergonomic stretching and exercise breaks, Computation’s 20th hackathon saw high turnout collaboration, experimentation, and fun.
