Scaling Commercial CFD Code at 3 Supercomputing Centers


Nov 14, 2017

The year isn’t over yet and already we've seen new records posted for proprietary physics-based simulations on two Cray machines – at the National Center for Supercomputing Applications (NCSA) and at King Abdullah University of Science and Technology (KAUST) - successfully pushing the limits of all the available nodes in those large machines.

NCSA scales CD-adapco’s STAR-CCM+ to new world record of 102,000 cores on Blue Waters


Jun 3, 2015

The National Center for Supercomputing Applications (NCSA) recently set a new world record by scaling CD-adapco's flagship simulation tool STAR-CCM+® to 102,000 cores on the Blue Waters supercomputer. STAR-CCM+ is a comprehensive multidisciplinary engineering simulation tool used across many industries to stimulate innovation and lower product development costs. CD-adapco joined with NCSA's Private Sector Program and Blue Waters manufacturer Cray to push the code to new heights and address the ever-increasing demands of fast turnaround time.

Pushing limits


May 28, 2015

NCSA's Private Sector Program (PSP) has a unique opportunity to work with non-academic codes, impact economic development, and make more complex simulations happen for industry partners, says Merle Giles, PSP director. High-performance computing (HPC) has become a core strategic technology enabling enhanced insight into product performance and improving the productivity by considering more design variants.But as companies increasingly seek to minimize time, quality, and cost pressures by using engineering simulation, they have been constrained by compute power. Both software developers and end-users face constraints when it comes to testing the limits of codes. They often don't have access to truly massive supercomputers and are focused on daily business needs, so they can't spare the time and manpower to attempt extreme scaling studies. PSP bridges the gap between partnering companies and computing resources and expertise.

NCSA Private Sector Program scales Fluent to 36,000 cores on Blue Waters


Nov 17, 2014

ANSYS and the National Center for Supercomputing Applications (NCSA) announced today that they have scaled ANSYS® Fluent® to 36,000 compute cores – an industry first that could lead to greater efficiencies and increased innovation throughout manufacturers’ product development processes. ... “We’re connecting all the dots,” said Ahmed Taha, the NCSA senior computational resource coordinator who led this extreme benchmarking project. “NCSA is unique in connecting the industrial users, the hardware and software vendors, and the domain expertise of our staff. In addition, this level of scalability for a commercial fluid dynamics solver is unprecedented on our system, especially considering the complexity of the model physics with transient, turbulent flow, chemical species transport and multiple non-reacting flows.”
