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...]

Extreme Scaling in CAE Applications

manufacturing-mechanical-vert (1)

With all the change that has happened around the high performance computing (HPC) environments used in manufacturing over the past 20 years, two constants have remained: 1) the computer-aided engineering (CAE) workload – and hence the demand for compute power – have nearly doubled every year; and 2) the names of the ISV applications used today for CAE simulations are pretty much the same as 20 years ago (e.g. NASTRAN, Abaqus, Fluent, LS-DYNA). The first constant is a direct result of CAE becoming a core element in the product design process. The second is a result of the constant enhancements in both features and performance made by the ISVs. The Move to Extreme Scalability It is the HPC performance, and specifically the parallel … [Read more...]

Supercomputing Creates Innovation Under the Hood

HLRS

German love for the engineering industries is renowned, so it isn't surprising that one of the biggest HPC systems in Europe is used to make innovations through technology a reality. The automotive sector, like many other research-centric industries, faces major challenges when it comes to taking new ideas and having them impact real-world products. The process of experimentation and trial needed to make new ideas a reality is long and expensive, both issues that supercomputing solutions are helping to address. For a clear example of this trend, look no further than the High Performance Computing Center Stuttgart (HLRS) of the University of Stuttgart. HLRS is among the leading supercomputing centers in Europe and has strong links to the … [Read more...]
