Driving Higher Performance for Advanced Structural Analysis

Altair RADIOSS* and Intel® Xeon® Scalable processors combine to provide an advanced solution stack for improved crashworthiness, safety, and manufacturability of automotive structural designs.

RADIOSS is a leading structural analysis solver for highly non-linear problems under dynamic loadings. It is used across all industries worldwide to improve the crashworthiness, safety, and manufacturability of structural designs.

Enormous advances in auto safety over the past several decades are due in no small part to the ongoing efforts by car manufacturers to make structural improvements during the design process. While the most dramatic testing may involve crash-test dummies piloting actual cars to destruction, the bulk of structural analysis happens in computer simulations. A structural analysis solver depended on by automotive, aerospace, electronics, and defense companies for more than 30 years, RADIOSS, and its companion tools are the basis for sophisticated understanding and prediction of structural design behaviors under extreme conditions.

At the same time customers continue to build more complex and sophisticated simulation models, they also strive to tighten development windows, to speed time to market with ever-improving designs. RADIOSS draws on synergies with Intel® architecture to drive the performance that enables both those goals. Co-engineering by Altair and Intel for RADIOSS on the new Intel® Xeon® Scalable processors builds significantly on previous results.

Faster Completion of a Crash Simulation
Performance engineers at Altair found that a crash simulation ran with up to 2.1X greater performance on the Intel® Xeon® Gold 6148 processor, compared with a processor two generations old.1 That baseline processor was introduced in 2014, just three years earlier, making it a viable comparison to servers that may be in wide use by customers. Even compared to more recent hardware—the Intel® Xeon® processor E5-2699 v4, introduced in 2016—the new processor showed up to a 1.64X performance increase.

“The Intel® Xeon® Scalable processor platform offers great computing power to run Altair HyperWorks* solvers and especially RADIOSS*. We are very pleased it is now available to our customers.”

Potential customer benefits from this improved performance are significant. Auto manufacturers can run more simulations based on more complex data sets and configurations, in less time. As a result, they can meet the ongoing challenge to increase driver and passenger safety while compressing design windows. Better safety ratings can help make those car makers more competitive, while perhaps also achieving the best result of all—saving lives.

Server Platform Benefits from Intel® Xeon® Scalable Processors
A range of hardware features built into the Intel® Xeon® Gold 6148 processor directly contribute to the acceleration of RADIOSS workloads. Built using a new microarchitecture based on 14-nanometer process technology, the processor features a redesigned memory subsystem with six channels. This advance works in conjunction with the new Intel® Ultra Path Interconnect (Intel® UPI), which provides a new, higher-bandwidth data path between processors, to offer improved system-level data handling, a critical contributor to performance on data-intensive RADIOSS workloads.

RADIOSS is also enabled to take advantage of Intel® Advanced Vector Extensions 512 (Intel® AVX-512) support in the Intel® Xeon® Scalable processors, including the Intel® Xeon® Gold 6148 processor. Improved vectorization based on Intel® AVX-512 instructions allows each processor register to hold twice as much data as predecessor technologies, getting more advantage out of available hardware resources. For example, a single register under Intel® AVX-512 can hold up to eight double-precision or 16 single-precision floating-point numbers, helping accelerate the floating-point calculations that are prevalent in RADIOSS simulations.

As a result of these hardware advances, RADIOSS customers can run more complex simulations in the same amount of time, run their existing simulations faster, and reduce design time, for potential cost savings and faster time to market.
