Research Note Abstract
We present a general algorithm for scheduling the application of cavity-based mesh modifications which enables parallel mesh adaptation on shared-memory parallel hardware including accelerators such as GPUs. We demonstrate this method on a mesh with objects moving in the fluid, and performance is studied on hardware including an Intel Knights Landing processor and an NVidia K80 GPU. Our code ports seamlessly between these architectures and has no architecture-specific algorithms.
