New supercomputing record set by ANSYS, HLRS and Cray ​

ANSYS, the High Performance Computing Center (HLRS) of the University of Stuttgart and Cray Inc. have set a new supercomputing world record enabling organizations to create complete virtual prototypes of products faster than ever. ANSYS Fluent has been scaled to 172,032 computer cores on the HLRS supercomputer Hazel Hen, a Cray XC40 system, running at 82 percent efficiency. This is nearly a 5x increase over the record set two years ago when Fluent was scaled to 36,000 cores.

By leveraging high performance computing (HPC), companies can rapidly iterate their products. Even though most organizations do not have access to this extreme core count level yet, users across all computing platforms from HPC clusters over Cloud to engineering desktops can take advantage of the breakthroughs that speed up computing at all levels.

“Our high-performance computing technology partnership with HLRS is delivering cutting-edge simulation capabilities,” said Wim Slagter, director of HPC and cloud marketing at ANSYS. “With the state-of-the-art resources and support from Cray, as well as access to government, industry and academia, we can use HPC to solve even more complex and challenging problems across any industry.”

The ANSYS, HLRS and Cray partnership was announced in 2015. The three have worked since then on profiling and benchmarking ANSYS’ simulation software for extreme HPC scalability and capability. The partnership proves that when combining the right expertise the ISV simulation software can scale to extreme loads, and broaden the scope of simulations, allowing for applicability to a much broader set of real-world problems and products. Through EXCELLERAT we plan to initiate and support more partnerships like this one, in order to solve even more HPC challenges of engineering.

“We see the role of HLRS as vital for industrial innovation,” said Michael M. Resch, HLRS director. “We not only provide the HPC platforms for industrial companies and scientific organizations but also support them in developing solutions for their research and their business based on extreme HPC capabilities. This partnership is a prime example that supercomputing can be brought to bear on some of the most pressing technical challenges of the day.”

“The role of HLRS is vital for industrial innovation”

The new record is critical as the demand for HPC to solve large-scale simulation challenges is growing across industries, especially in the aerospace and automotive industries, where product simulation models are becoming larger and more complex. We can now tackle more complex and broader systems level simulation needed to develop the smarter and greener products of tomorrow.

“This record-setting scaling of ANSYS software on the Cray XC40 supercomputer at HLRS proves that close collaborations with customers and partners can produce exceptional results for running complex simulations,” said Fred Kohout, senior vice president and chief marketing officer at Cray. “The highly-integrated architecture of the Cray XC40 and its Aries interconnect are designed for applications at any scale, and allow scientists and engineers to push the boundaries of advanced simulations.”
