Assessing large magnitude (greater than 6 on the Richter scale) earthquake hazards on a regional (up to 100 kilometers) scale takes big machines. To resolve the frequencies important to engineering analysis of the built environment (up to 10 Hz or higher), numerical simulations of earthquake motions must be done on today's most powerful computers.

Normally, in a large-scale emergency, distributed energy resources (DERs) -- such as the energy produced by solar panels at customers' homes -- are shut off to protect the greater electrical grid. But a new project headed by Lawrence Livermore National Laboratory (LLNL) aims to utilize these resources for restoration and recovery operations, boosting the grid's ability to bounce back from a blackout or cascading outage, and potentially reducing customer reconnection time to a matter of hours.

To run efficiently on Sierra, applications must be modified to achieve a level of task division and coordination well beyond what previous systems demanded.

In January 2016, President Obama signed a Presidential Memorandum establishing a first-of-its-kind federal task force to end cancer as we know it. Led by Vice President Joe Biden, the Cancer Moonshot is a national effort to double the rate of progress—to make a decade's worth of advances in cancer prevention, diagnosis, treatment, and care in five years—and to ultimately end cancer. Lawrence Livermore National Laboratory's (LLNL) high-performance computing will play a major role in the initiative.

The Department of Energy (DOE) has launched three new pilot projects focused on bringing together nearly 100 cancer researchers, care providers, computer scientists and engineers to apply the nation's most advanced supercomputing capabilities to analyze data from preclinical models in cancer, molecular interaction data, and cancer surveillance data across four DOE national laboratories.

EVERYTHING changes. Nowhere is that maxim more apparent than in the world of computing. From smartphones and tablets to mainframes and supercomputers, the system architecture—how a machine’s nodes and network are designed—evolves rapidly as new versions replace old. As home computer users know, systems can change dramatically between generations, especially in a field where five years is a long time. Computational scientists at Lawrence Livermore and other Department of Energy (DOE) national laboratories must continually prepare for the next increase in computational power so that the transition to a new machine does not arrest efforts to meet important national missions.

That next jump in power will be a big one, as new machines begin to approach exascale computing. Exascale systems will process 10¹⁸ floating-point operations per second (flops), making them 1,000 times faster than the petascale systems that arrived in the late 2000s. Computational scientists will need to address a number of high-performance computing (HPC) challenges to ensure that these systems can meet the rising performance demands and operate within strict power constraints.

We report on the development of many-body density functional tight binding (DFTB) models for carbon, which include either explicit or implicit calculation of multi-center terms in the Hamiltonian. We show that all of our methods yield accurate eigenstates and eigenfunctions for both ambient diamond and transitions to molten, metallic states. We then determine a three-body repulsive energy to compute accurate equation of state and structural properties for carbon under these conditions. Our results indicate a straightforward approach by which many-body effects can be included in DFTB, thus extending the method to a wide variety of systems and thermodynamic conditions.
