Exploit the exascale computing to make earthquake simulated codes more powerful

Dec 30, 2020 – In an introductory podcast and blog post, Scott Gibson, Communications Specialist at the Exascale Computing Project, discusses the limitations of traditional earthquake simulation methods, and how the Earthquake Sim, or EQSIM, project develops more effective prediction models to help inform Resilient infrastructure design. The blog post is included in a section below.

Historically, engineers and scientists have studied past earthquakes to try to predict future earthquakes. But in the past decade or so, the interest in using high-performance computing and physics-based models to simulate seismic processes on large computers has grown exponentially.

Scientists and engineers want to simulate what could be referred to as complete end-to-end earthquake processes. This means understanding what is happening from the time an earthquake ruptures through the damaging effects of seismic waves on bridges and buildings. Our guest in this episode is an expert in earthquake modeling and computer simulation.

David McLean is Professor and Director of the Earthquake Research Center in Civil Engineering in the Department of Civil and Environmental Engineering at the University of Nevada, Reno. He is a senior scientist at Lawrence Berkeley National Laboratory. For the US Department of Energy’s Exascale Computing Project, he’s leading a sub-project called Earthquake Sim, or EQSIM.

Man-made structures vibrate at a high frequency that is difficult to match in simulating ground motion. Mismatch was a hindrance to performing simulations of end-to-end earthquakes. However, with the help of upcoming Exclusive computing platforms, the EQSIM project aims to break through this barrier to help design bridges and buildings that will be more resilient when the next major earthquake strikes.

Our Topics: The limitations of the traditional approach to earthquake prediction, what is involved in simulating end-to-end earthquake processes, why simulations are important, how the EQSIM project is pioneering the most effective earthquake simulations, what the EQSIM accomplished and where it is headed.

What Are The Main Benefits Of Comparing Car Insurance Quotes Online

LOS ANGELES, CA / ACCESSWIRE / June 24, 2020, / Compare-autoinsurance.Org has launched a new blog post that presents the main benefits of comparing multiple car insurance quotes. For more info and free online quotes, please visit https://compare-autoinsurance.Org/the-advantages-of-comparing-prices-with-car-insurance-quotes-online/ The modern society has numerous technological advantages. One important advantage is the speed at which information is sent and received. With the help of the internet, the shopping habits of many persons have drastically changed. The car insurance industry hasn't remained untouched by these changes. On the internet, drivers can compare insurance prices and find out which sellers have the best offers. View photos The advantages of comparing online car insurance quotes are the following: Online quotes can be obtained from anywhere and at any time. Unlike physical insurance agencies, websites don't have a specific schedule and they are available at any time. Drivers that have busy working schedules, can compare quotes from anywhere and at any time, even at midnight. Multiple choices. Almost all insurance providers, no matter if they are well-known brands or just local insurers, have an online presence. Online quotes will allow policyholders the chance to discover multiple insurance companies and check their prices. Drivers are no longer required to get quotes from just a few known insurance companies. Also, local and regional insurers can provide lower insurance rates for the same services. Accurate insurance estimates. Online quotes can only be accurate if the customers provide accurate and real info about their car models and driving history. Lying about past driving incidents can make the price estimates to be lower, but when dealing with an insurance company lying to them is useless. Usually, insurance companies will do research about a potential customer before granting him coverage. Online quotes can be sorted easily. Although drivers are recommended to not choose a policy just based on its price, drivers can easily sort quotes by insurance price. Using brokerage websites will allow drivers to get quotes from multiple insurers, thus making the comparison faster and easier. For additional info, money-saving tips, and free car insurance quotes, visit https://compare-autoinsurance.Org/ Compare-autoinsurance.Org is an online provider of life, home, health, and auto insurance quotes.
