The National Nuclear Security Administration (NNSA) and Cray have entered into a contract agreement for a next-generation supercomputer, called Trinity, to advance the mission for the Stockpile Stewardship Program. Managed by NNSA, Trinity is a joint effort of the New Mexico Alliance for Computing at Extreme Scale between Los Alamos and Sandia national laboratories as part of the NNSA Advanced Simulation and Computing Program.
A relic from long before the age of supercomputers, the 169-year-old math strategy called the Jacobi iterative method is widely dismissed today as too slow to be useful. But thanks to a curious, numbers-savvy engineering student and his professor, it may soon get a new lease on life.
"Big data" is playing an increasingly big role in the renewable energy industry and the transformation of the nation's electrical grid, and no single entity provides a better tool for such data than the Energy Department's Energy Systems Integration Facility (ESIF) located on the campus of the National Renewable Energy Laboratory (NREL).
Supercomputer simulations have shown that clusters of a protein linked to cancer warp cell membranes. This research on these protein clusters, or aggregates as scientists call them, could help guide design of new anticancer drugs.
Researchers from Westinghouse Electric Company and the Consortium for Advanced Simulation of LWRs (CASL), a U.S. Department of Energy (DOE) Innovation Hub, performed core physics simulations of the AP1000® PWR startup core using CASL’s Virtual Environment for Reactor Application (VERA).
Engineers from THESAN srl, an Italian SME active in the renewable energy sector, teamed up with the Italian supercomputing center CINECA to develop simulation driven engineering of hydroelectric turbines. The engineers and researchers built an HPC based workflow to optimize the design of a new class of hydroelectric turbines.
Researchers from Argonne National Laboratory conducted one of the largest internal combustion engine simulations. Predictive internal combustion engine simulations necessitate very fine spatial and temporal resolutions, high-fidelity and robust two-phase flow, spray, turbulence, combustion, and emission models.
University of Wisconsin Researchers utilized HPC resources in combination with multiple advanced forms of protein structure prediction algorithms and deep sequence data mining to construct a highly plausible capsid model for Rhinovirus-C (~600,000 atoms). The simulation model helps researchers in explaining why the existing pharmaceuticals don’t work on this virus.
Inspired by anomalies that arise in certain mathematical equations, researchers have demonstrated a laser system that paradoxically turns off when more power is added rather than becoming continuously brighter. The finding could lead to new ways to manipulate the interaction of electronics and light, an important tool in modern communications networks and high-speed information processing.
IDC has announced the availability of the first in-depth forecasts for high performance data analysis (HPDA), the fast-growing worldwide market for big data workloads that use high performance computing resources. IDC forecasts that the server market for HPDA will grow rapidly at 23.5 percent compound annual growth rate (CAGR) to reach $2.7 billion in 2018 and the related storage market will expand to about $1.6 billion in the same year
Researchers at The University of Tennessee are a step closer to creating a prophylactic drug that would neutralize the deadly effects of the chemical weapons used in Syria and elsewhere. Jeremy Smith, UT-ORNL Governor’s Chair and an expert in computational biology, is part of the team that is trying to engineer enzymes — called bioscavengers — so they work more efficiently against chemical weapons.
Engineering turbomachines that routinely punch past the sound barrier will require more brain than brawn. In fact, it will take more than a thousand-trillion calculations per second on the nation’s most powerful supercomputer to simulate the precise design spaces and complex fluid dynamics that affect machine performance.
While hybrids and electrics may grab the headlines, the real frontier in fuel economy is the switch to lighter materials. Automakers have been experimenting for decades with lightweighting, as the practice is known, but the effort is gaining urgency with the adoption of tougher fuel efficiency standards. To meet the U.S. government's goal of nearly doubling average fuel economy to 45 mpg by 2025, cars need to lose some serious pounds.
Like a Formula One race car stuck in a traffic jam, HPC hardware performance is frequently hampered by HPC software. This is because some of the most widely used application codes have not been updated for years, if ever, leaving them unable to leverage advances in parallel systems. As hardware power moves toward exascale, the imbalance between hardware and software will only get worse. The problem of updating essential scientific ...

Scientists may be years away from successfully emulating a human or animal brain for research purposes, but the significant — and perhaps unexpected — ethical challenges such work presents have been outlined in a thought-provoking article in the Journal of Experimental & Theoretical Artificial Intelligence.
Scientists have developed a sophisticated computer modelling simulation to explore how cells of the fruit fly react to changes in the environment. The research is part of an on-going study that is investigating how external environmental factors impact on health and disease. The model shows how cells of the fruit fly communicate with each other during its development.
A recent study into the biomechanics of ants — a common insect that can amazingly lift objects many times heavier than its own body — might unlock one of nature’s little mysteries and, quite possibly, open the door to advancements in robotic engineering. Engineers combined laboratory testing and computational modeling conducted to determine the relationship between mechanical function, structural design and material properties ...
Paradigm 14 is designed to enable effective seismic data processing and imaging, velocity modeling and seismic interpretation. It includes features that cover the entire upstream workflow — from processing and imaging to interpretation and modeling, reservoir characterization, reservoir engineering and drilling, and data management.
A rapidly melting section of the West Antarctic Ice Sheet appears to be in irreversible decline, with nothing to stop the entire glacial basin from disappearing into the sea, according to researchers at UC Irvine and NASA. The new study presents multiple lines of evidence — incorporating 40 years of observations — that six massive glaciers in the Amundsen Sea sector “have passed the point of no return,”
Move over, Matrix — astronomers have done you one better. They have created the first realistic virtual universe using a computer simulation called "Illustris." Illustris can recreate 13 billion years of cosmic evolution in a cube 350 million light-years on a side with unprecedented resolution.
The melting of a rather small ice volume on East Antarctica's shore could trigger a persistent ice discharge into the ocean, resulting in unstoppable sea-level rise for thousands of years to come. This is shown in a study published in Nature Climate Change. The findings are based on computer simulations of the Antarctic ice flow using improved data of the ground profile underneath the ice sheet.
Twenty years ago, Philip Platzman and Allen Mills, Jr. at Bell Laboratories proposed that a gamma-ray laser could be made from a Bose-Einstein condensate (BEC) of positronium, the simplest atom made of both matter and antimatter. That was a year before a BEC of any kind of atom was available in any laboratory. Today, BECs have been made of 13 different elements.
It is well established that modern humans originated in Africa, before moving out to inhabit rest of the planet. They first spread into Asia and Europe via the Arabian Peninsula, and those in the Far East eventually reached America and the Pacific islands. However, this simple picture does not explain several groups found across Asia and Oceania. Now, by looking at genetic and archaeological data, researchers might have found the answer
Mudslides. Landslides. Volcanic debris flows. Avalanches. Falling rocks... They can come along so suddenly that people, homes, roads and even towns are buried or destroyed without much warning. Recently, we've had dramatic reminders of this, such as the mudslide in Oso, WA, where 41 people died; an avalanche on Mt. Everest that killed 13 experienced Sherpas and another landslide event in Jackson, WY.
