Summary

In this paper the scalability of standard PCG and PBiCG solvers implemented in OpenFOAM (Open Source Field Operation and Manipulation C++ libraries) on many-core architectures is presented. Scalability tests are performed using various hardware and different implementations of standard PCG and PBiCG Krylov iterative methods. Speed up of various implementations of solvers for linear equations using GPU and MIC accelerators is compared in this paper. Numerical experiments of two and three dimensonal lid-driven cavity flows for several cases with various numbers of cells are used.
