On the Multi-GPU Computing of a Reconstructed Discontinuous Galerkin Method for Compressible Flows on 3D Hybrid Grids
2014
7th AIAA Theoretical Fluid Mechanics Conference
unpublished
A multi-GPU accelerated, third-order, reconstructed discontinuous Galerkin method, namely RDG(P1P2), has been developed based on the OpenACC directives for compressible flows on 3D hybrid grids. The present scheme requires minimum intrusion and algorithm alteration to an existing CPU code, which renders an e cient design approach for upgrading a legacy CFD solver with the GPU-computing capability while maintaining its portability across multiple platforms. The grid partitioning is performed
