Crash/safety simulation is one of the most widely adopted HPC applications in the automotive industry and a core technology in the vehicle development process. As the volume and complexity of these simulations increases, the compute requirements are growing exponentially. Advancing the parallel performance and efficiency of explicit structural simulations is critical, and companies that integrate their HPC hardware and software strategies for simulation-driven design are more successful in developing better vehicles faster.

In this live webinar, Altair and Cray experts will discuss results of a crash simulation study using RADIOSS running on a Cray® XC40™ system with 16,000+ cores (as discussed in a recent benchmark paper) – and will present two new examples to illustrate RADIOSS performance for very large models: A b-pillar model with a very fine mesh of 10 million solid elements (built for a PRACE project with PSA and Ecole Polytechique to asses crash failure prediction), and a new demo model of 25 million elements.

Greg has worked in the high performance computing (HPC) field for over 25 years, most recently with Cray Inc. as the manufacturing segment manager. Greg’s primary focus has been on application performance on HPC architectures. This has involved close cooperation with application developers and users to improve real performance in production environments. Prior to Cray, Greg worked at IBM for 10 years on the HPC team and 16 years at Cray Research in the application department.
Pierre Carrier has a B.Sc. and M.Sc. in applied mathematics from the University of Montreal and Polytechnique in Montreal; a D.E.A. (equivalent to master's thesis) from the Ecole des Mines de Paris (CEMEF in Sophia-Antipolis); and a Ph.D. in materials science from the University of Montreal. Pierre joined Cray Inc. in October 2012 and has since been working on benchmarking multiple applications, such as RADIOSS.
An expert in software optimization and parallelization on clusters, multicore architectures, accelerators and coprocessors, Eric developed the hybrid MPP parallel version of RADIOSS finite element software. After receiving an MSc degree in computer science, Eric started his career in 1994 at CNRS, Laboratoire Informatique du Parallélisme. He joined Mecalog in 1994 and worked there until its acquisition by Altair in 2006. Eric holds an executive MBA from HEC, a French business school.
