Lawrence Livermore’s 2016 spring hackathon saw an all-time high of 68 people participate and matched last year’s spring high of 39 different projects.
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.
For experiments performed at the National Ignition Facility (NIF), the goal is not just to measure the interaction between the target and the laser beams. Researchers also need to understand, on a fundamental level, what is happening to the material in the target and how it’s changing over time. This capability to see inside the target as it interacts with the laser beams is especially useful in high-energy-density experiments and those exploring material strength.
Livermore researchers have developed a toolset for solving data center bottlenecks.
On November 12 and 13, staff members from nearly every division of the Computation Directorate turned out for the fall hackathon, held at the High Performance Computing Innovation Center on the Livermore Valley Open Campus.
Julia Ramirez helps automate and streamline LLNL processes for preparing reports and responding to audits.
Eight project teams with Computation employees were recognized for their institutional impact, demonstrated cost savings, and improvement of Laboratory programs and operations.
Livermore Computing’s latest hackathon, held on July 23 and 24, attracted 79 “hackers,” the event’s largest participant pool to date.
A growing number of companies that offer products for cloud computing and large-scale data storage are using Livermore’s ZFS on Linux in their products.
Sequoia is one of the most efficient systems in the world for processing extremely vast (petabyte and exabyte-size) data sets.
LLNL’s Sequoia is ranked among the world’s most powerful supercomputers.
