SGI Altix ICE 8400 demonstrated unmatched parallel scaling up to 3,072 cores with a rating of 1,333.3 standard benchmark jobs per day. It also proved the ability to run ANSYS FLUENT on all 4,092 cores. To date, no other cluster has reported ANSYS FLUENT benchmark results above 2,048 cores, which was also posted by SGI. The ANSYS FLUENT benchmark performance increase was achieved with the help of SGI MPI PerfBoost.
"This world record demonstrates the superior scalability and computing power of the SGI system with SGI MPI PerfBoost", stated Christian Tanasescu, vice president of software engineering at SGI. "Part of our recently announced ProPack 7 suite, SGI's MPI PerfBoost allows technical applications written for other MPI implementations to take advantage of the performance, robustness and scalability of SGI Message Passage Toolkit (MPI) at runtime without recompiling."
ANSYS FLUENT software is used for engineering simulations involving fluid flow problems and is based on a numerical technique called computational fluid dynamics (CFD). The ANSYS suite of integrated multiphysics helps organisations to virtually test their product designs against a variety of real-world operating conditions. As product designs become more complex, the ability to solve higher-fidelity models is critical to reduce the need for expensive physical testing, yielding results within days instead of weeks and enabling engineers to consider multiple design ideas.
"SGI has once again pushed the boundary to demonstrate ANSYS FLUENT scalability at this extreme level", stated Josh Fredberg, vice president of marketing at ANSYS. "We invest heavily in HPC performance tuning in order to deliver scalability that our customers need for their highest fidelity engineering simulations. Our technical collaboration with SGI is a key part of our success and helps us deliver HPC technology that is second to none."
