Teams at Saudi Aramco using the Shaheen II supercomputer at King Abdullah University of Science and Technology (KAUST) have managed to scale ANSYS Fluent across 200,000 cores, marking top-end scaling for the commercial engineering code.

The news last year of a code scalability effort that topped out at 36,000 cores on the Blue Waters machine at the National Center for Supercomputing Applications (NCSA) was impressive. That was big news for ANSYS and NCSA, but also a major milestone for Cray. Just as Blue Waters is a Cray system, albeit one at the outer reaches of its lifespan (it was installed …
