Modularised HLS(Vivado C/C++) based implementation of contrasting stencil applications targetting Xilinx FPGAs. Implementation currently includes following applications.

• poisson (5-point 2D stencil)
• jac2D9pt (9-point 2D stencil)
• jac3D7pt (7-point 3D stencil)
• RTM (multiple stencil loops with 25 point 3D stencils)
• blacksholes (3-point 1D stencil. Xilinx batch only)

Batched version targets small and medium sized meshes while Spatially blocked/Tiled version targets larger meshes which fits into 4GB buffer limit.

All the above applications are implmented using OPS framework as well to support traditional architectures. This can be used to generate optimised target code for Muticore CPUs and GPUs.

We would like to thank Jacques Du Toit and Tim Schmielau at NAG UK Ltd., for providing us the RTM application and for their valuable advice.
