S7672 - OpenACC Best Practices: Accelerating the C++ NUMECA FINE/Open CFD Solver

Session Speakers
Session Description

We'll demonstrate the maturity and capabilities of OpenACC and the PGI compiler suite in a professional C++ programming environment. We'll explore in detail the adaptation of the general purpose NUMECA FINE/Open CFD solver for heterogeneous CPU+GPU execution. We'll give extra attention to OpenACC tips and tricks used to efficiently port the existing C++ programming model with minimal code modifications. Sample code blocks will be used to clearly demonstrate the implementation principles in a clear and concise manner. Finally, we'll present simulations completed in partnership with Dresser-Rand on the OLCF Titan supercomputer, showcasing the scientific capabilities of FINE/Open and the improvements in simulation turnaround time made possible through the use of OpenACC.
