New York and London. May 13, 2015

CD-adapco, the largest privately held CFD-focused provider of Computer Aided Engineering software, announced today a new standard in performance and scalability for industrial CFD software. Working in partnership with High Performance Computing Center Stuttgart (HLRS) and SICOS BW, STAR-CCM+® was run on the entirety of the 1.045 PetaFlop Hermit cluster, managing to maintain perfect scalability beyond 55,000 cores.

The work was completed as part of the ongoing multi-year project to benchmark, profile and ensure optimal STAR-CCM+ performance and scalability on petascale computing systems. A number of different benchmark cases were run, ranging in size from 500 million to 2 billion cells, all generated automatically using parallel meshing technology and without the need to split the geometry into multiple blocks.

“The ability to perform simulations with such massive core counts is a real breakthrough for the CAE industry, and a direct result of our close collaboration with HLRS,” said CD-adapco Senior VP of Product Management, Jean-Claude Ercolanelli. “In under a year, this project has allowed STAR-CCM+ to effectively run, and scale, on over 50,000 cores. That is very encouraging, and I am excited to see what other breakthroughs we can make. "The results allow STAR-CCM+ users to gain maximum utility from all of the computing resources that are available to them.”

“These results are a fitting send-off for Hermit which now goes into retirement,” added Dr. Uwe Küster, Head of Numerical Methods & Libraries of HLRS. “We have shown that the use of petascale machines for building and solving industrial CFD problems is a realistic proposition. I’m encouraged that through this ongoing collaborative project we will allow industry to push their simulation capabilities even further.”
