Oktoberfest: Prost! to Beer and Big Data

Octoberfest_Blog

Bavarian culture has spread its wings and has influenced the world with its beer-drinking tradition. Oktoberfest, a more than 200-year-old celebration that began in Munich, Germany, is still well under way. These days, Oktoberfest is celebrated not only in Bavaria, but also around the globe in places such as London and Dublin and many cities in the United States. As an enthusiast of both beer and data, I find myself thinking about how even beer production and marketing relate to big data. Even in the world of Oktoberfest, there is a massive amount of information to be mined, analyzed and put to use. Questions such as “What types beer are sold the most?” and “Depending on the time, day, place and weather, which areas host the heaviest … [Read more...]

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...]

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...]

Record LS-DYNA “car2car” Performance Paves the Way for Future Crash/Safety Simulation

Altair Webcast

A Cray supercomputer has set a speed record in a crash/safety simulation used by the automotive and aerospace industries. Leveraging the scalability of the Aries interconnect in the Cray® XC30™ supercomputer, engineers ran the “car2car” model, a 2.4-million element crash/safety simulation, in under 1,000 seconds. The LS-DYNA results are posted on topcrunch.org, the site that was created to track the performance of HPC systems on actual engineering applications codes. In addition to the job turnaround record (931 seconds), the result set a record for the level of parallelism (3,000 cores). As the automotive and aerospace industries continue to run larger and more complex simulations, the performance and scalability of the applications … [Read more...]
