- Abstract
In this paper, we investigate the scalability of OpenFOAM for the viscoelastic solver which is implemented in our previous study on HPC platforms. Results show that the solver scales reasonably well up to 256 cores. Further profiling shows that the scalability is greatly restricted by global reduction, which is introduced by numerous scalar product operations of parallel PCG algorithm in OpenFOAM.
