The High Performance Computing Center (HLRS) Stuttgart, ANSYS, and Cray Inc. have set a new supercomputing world record by scaling ANSYS Fluent to more than 170,000 computer cores on the GCS high performance computing (HPC) system Hazel Hen hosted at HLRS.
ANSYS Fluent, a powerful computational fluid dynamics (CFD) software tool, empowers organizations to create innovative, complete virtual prototypes of their products faster and more efficiently than ever as they optimize their product's performance. Scaling this software to 172,032 cores on the HLRS supercomputer, a CRAY XC40-system, running at 82 percent efficiency, is nearly a 5-fold increase over the record set on the HLRS CRAY supercomputing platform two years ago when Fluent was scaled to 36,000 cores.
HLRS, CRAY, and ANSYS teamed up in 2015 not only to ensure that ANSYS’ simulation software scales to extreme loads, but also to broaden the scope of simulations, allowing for applicability to a much broader set of real-world problems and products. Users across all computing platforms from HPC clusters over Cloud to engineering desktops can take advantage of the now achieved breakthroughs which speed up computing at all levels.
“We consider the role of HLRS vital for industrial innovation,” said Prof. Dr.-Ing. Michael M. Resch, Director of the HLRS. “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.”
