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 … [Read more...]

HPC Centers Role in Driving CAE Simulation

blue-waters-case-front-3d

My recent blog posts have focused on performance enhancements to CAE applications and especially the scalability of ISV applications. A key point of this discussion is that it takes team effort to achieve these results. You need production models from the user community, the cooperation of application developers and computational scientists, access to large compute resources, and HPC system expertise. In this blog, I want to highlight the critical role HPC centers play in providing resources and expertise to improve the performance and effectiveness of CAE simulation for manufacturing companies. Leading HPC Centers Several of the largest HPC systems in the world are located at national HPC research centers. These centers are often … [Read more...]

Scaling Performance of Explicit Structural Applications

manufacturing-mechanical-vert (1)

A few months back I wrote a blog on “Extreme Scaling in CAE Applications” which showed results for CFD applications scaling to over 10,000 cores. This blog will focus on the scaling performance of explicit structural analysis applications (often referred to as “crash simulation” applications). There has been increased emphasis and significant improvements in the scaling of the explicit structural codes. Because these codes are important across several industries, this work merits a separate post. Background The most popular explicit structural analysis codes are Abaqus/Explicit, LS-DYNA®, PAM-CRASH®, and RADIOSS®. These applications are heavily used in the automotive industry for crash and safety analysis. They are also … [Read more...]

Another Exciting Year

Pete's Blog_holiday 2013

As we near the end of 2013, Cray is closing out one of the most transformative years in our long and proud history. In just this year alone, we successfully integrated two strategic acquisitions, won a number of large supercomputing contracts at customer sites around the world, significantly expanded our business and portfolio of solutions, continued to build the financial strength of the company, and added a host of highly-talented individuals to our team. It’s been quite a year! Since the early days of our company, starting with our iconic founder Seymour Cray, we have been a trusted partner to customers around the world with a commitment to do two things really well:  be focused on their success and help them to see around the next … [Read more...]
