Code Optimization Yields Three-Fold Increase in Engine Simulation Speed
Researchers at Argonne National Laboratory are partnering with Convergent Science, Inc. (CSI) to speed up a key piece of modeling and simulation software to ensure computer cycles are used as effectively as possible, reducing product development time and resulting in better engines. The research is part of Argonne"s Virtual Engine Research Institute and Fuels Initiative (VERIFI), which is working with CSI to optimize the company"s CONVERGE code, a CFD software program widely used in industry to conduct modeling and simulation for engine design. When the project first started, simulations ran on systems with 50 cores. VERIFI scaled up those numbers to 1,000 cores, and recently conducted an engine simulation on 4,096 cores.

In this video, using high-performance computer-generated models, VERIFI researchers demonstrated that in gasoline compression ignition, varying the start of injection (SOI) timing produces significant differences in the reactivity of the the fuel mixture, delaying ignition.
