Webinar: POP Case Study: 3x Speed Improvement for Zenotech’s zCFD Solver

12. March 2019 @ 14:00 - 15:00

zCFD by Zenotech is a density based finite volume and Discontinuous Galerkin (DG) computational fluid dynamics (CFD) solver for steady-state or time-dependent flow simulation. It decomposes domains using unstructured meshes. It is written in Python and C++ and parallelised with OpenMP and MPI.

This webinar will describe the work that POP and Zenotech undertook to investigate the performance of zCFD. An initial Performance Audit using Intel’s VTune Amplifier performance profiler identified several areas of potential improvement, which Zenotech went on to address in a POP Proof-of-Concept (PoC) study. As a result of the PoC, zCFD ran 3x faster on a representative input case.

In this 30-minute live webinar, we will describe:

  • An introduction to POP’s performance analysis methodology;
  • How Intel VTune was used to gain performance insights;
  • The modifications made to zCFD as a result.
