We describe the performance of a 3D unstructured mesh compressible flow solver on graphics processing unit (GPU) hardware. Using a graph-theoretic optimization approach, we achieve speed-ups of 4 − 5 × on meshes up to 107 tetrahedra. Hybrid GPU-OpenMP calculations with adaptive mesh refinement are also demonstrated.
