Recent Crash Test Results Highlight the Need for Enhanced Simulation

IIHS small crash

In July the Insurance Institute for Highway Safety (IIHS) published crash test results for the “small overlap front crash test,” in which only one of the 12 cars tested earned a “good” rating.  These results, combined with the results of earlier tests, led Consumer Reports to publish a headline reading, “Most Small Cars Bomb New Small-Overlap Crash Test.” At the same time, Nissan presented an excellent paper on the computer simulation challenges of the small overlap test. This is an example of the increasingly stringent requirements for automotive safety and why the use of high performance computing (HPC) for crash safety simulation is critical in the automotive design process. There are dozens of crash load cases evaluated in the … [Read more...]

Exascale Computing for Seismic Exploration

PGS01718_300_0

The exascale race — toward machines capable of executing 1 quintillion (1018) operations per second — is well under way. The U.S., Japan, China and Europe have all established programs to enable exascale capabilities by around 2020. In the U.S., leading the charge toward significant HPC milestones usually falls to the Department of Energy (DOE): Both its Office of Science and the National Nuclear Security Administration have significant interest in and benefit from ever-increasing levels of modeling, simulation and data-processing capabilities for a variety of applications. Both can leverage critical resources (facilities and people), institutional expertise and deep know-how, if not intellectual property, in this pursuit. Not all … [Read more...]

Unconventional ways Supercomputers are Used: Part 2

Coffee2_blogImage-

We talk a lot about how high performance computing systems are on the forefront of science, but it's also fun to take a step back and look at some of the more unusual ways that supercomputers are impacting our lives. In a previous post, I discussed how supercomputing systems are being used in everything from ice cream physics to baseball and dirty diapers. Now we're back with part two of our series on unconventional uses of supercomputers. The Lord of the Rings Considering this movie’s high-flying, detailed special effects, I'm not surprised the director, Peter Jackson, turned to supercomputing to help create these lifelike experiences. To make the weather, buildings and vegetation accurate enough to turn J.R.R. Tolkien's Middle Earth … [Read more...]

Supercomputers: The Solution to Physical Test Limitations in Automotive Manufacturing

During the past few decades the world of science has changed, moving from physical experimentation alone to an environment in which simulations are of primary importance. In the automotive industry, research and design is now so advanced that it’s following in the footsteps of science and moving away from physical testing. Supercomputing has allowed automobile manufacturers to transition to a simulation-driven world. The innovative use of new materials in vehicle design is becoming the norm for automotive manufacturers — honeycomb structures and increased aluminum use being an example. With more advanced design elements coming into play, numerous manufacturing challenges are emerging; including the need for a greater number of … [Read more...]

Using HPC Techniques to Accelerate NGS Workflows

Life Sciences_small

Next-generation sequencing (NGS) describes the modern nucleotide sequencing technologies that allow analysis of genetic material with unprecedented speed and efficiency. Its advent is shifting genome assembly from a problem of laboratory-based chemistry to one well suited to high performance computing (HPC). In simple terms, NGS involves breaking up long DNA or RNA molecules into millions of small, fragments (50 to 200 nucleotides), defined as a “reads” to be assembled into larger fragments called contigs. The process of taking genetic material, processing it on a sequencer, passing it to an HPC system for assembly, and outputting digital information in a form useful for research is contained in a “workflow,” the end-to-end flow of … [Read more...]
