Query: GPU Acceleration of Hermite Methods for the Simulation of Wave
  Propagation   The Hermite methods of Goodrich, Hagstrom, and Lorenz (2006) use Hermite
interpolation to construct high order numerical methods for hyperbolic initial
value problems. The structure of the method has several favorable features for
parallel computing. In this work, we propose algorithms that take advantage of
the many-core architecture of Graphics Processing Units. The algorithm exploits
the compact stencil of Hermite methods and uses data structures that allow for
efficient data load and stores. Additionally the highly localized evolution
operator of Hermite methods allows us to combine multi-stage time-stepping
methods within the new algorithms incurring minimal accesses of global memory.
Using a scalar linear wave equation, we study the algorithm by considering
Hermite interpolation and evolution as individual kernels and alternatively
combined them into a monolithic kernel. For both approaches we demonstrate
strategies to increase performance. Our numerical experiments show that
although a two kernel approach allows for better performance on the hardware, a
monolithic kernel can offer a comparable time to solution with less global
memory usage.
